No SPI
New version of USB Host library has been uploaded to gitHub. I managed to find a couple of bugs and solve some compatibility issues. The biggest change, however, has been made on the very lowest level of the library – SPI transfers between Arduino and MAX3421E registers.
From the beginning, USB Host firmware relied on Arduino Playground SPI library. Starting from version 0018 of Arduino IDE, this library became part of the distro. Two versions after that, Arduino team decided to re-write SPI library, among other things changing function names. As a result, USB Host code became incompatible with “stock” SPI library. To remedy the situation, I incorporated SPI routines directly into MAX3421E support code. The new code is independent of Arduino SPI library and builds correctly on “old” (i.e. 0017) and “new” (0021) versions of Arduino IDE. In addition to that, new code accounts for SPI pinout difference between Arduino variants and works on both Atmega 328 and Atmega 1280/2560 based boards. ( Note: the current rev1.x USB Host Shield still needs to be modified to work with Megas )
The new library can be downloaded from USB Host Shield gitHub repository. If you are upgrading existing installation of the library, please make a backup copy before downoading! I checked it against all code examples and USB devices in my possession and everything works without a hitch. However, code written with tight timing may stop working because of speed difference since new SPI routines are slightly faster.
As you can see in the title picture ( click on it to enlarge ), the line #include "Spi.h" is no longer needed. In next several days I’m going to update all USB examples on this site to match the new code. If you have any any problems with the library, please let me know!
Oleg.
I get “Error: OSCOKIRQ failed to assert” when I plug in my Logitech LX710 combo with the new library :S
Which shield variant are you using?
This one ->
hold on, link didn’t work… this one -> http://www.sparkfun.com/products/9947
I haven’t checked the code against Sparkfun shield, it can be incompatible. Try this: in Max3421e_h comment out line 41, which reads ‘SPSR = 0x01;’, then recompile and see if an error persists.
yep, still error.
I can’t replicate the error on my shields, could be specific to SF variant. Try to run board test from the examples and see where it breaks – you should be able to continue past OSCOKIRQ error.
turns out the 5v regulator blew, found out because my computer shut down when I connected the usb cable when Vin was connected to 8v. I’m pretty sure that’s the culprit 😛
In which way the hostshield must be modified to work with Arduino Mega (Atmeaga 2560)? I read the hardware-troubleshootig and searched for it, but couldnt find anything.
Look at the schematic of say Duemilanove and Mega. The SPI pins – SCK, MISO, MOSI are on pins outside the shield when you connect it to Mega. You need to solder wires to SPI pins on the shield and connect them to SPI pins on Mega.
I want to to connect a WiiMote-Controller with the Arduino. I allready have the rev1.21 USB Host shield and a Arduino Mega (Atmega2560). I tried to Upload the wiiblue.pde with the updated header-files, but i have erros while compiling.(I deleted the line including SPI.h; in arduino0020)
The error while compiling is:
arduino-0020\libraries\Wiiblue/ch9.h:102: error: ‘byte’ does not name a type
and many of the same but in different lines.
tryed to fix the error with
typedef unsigned char byte;
ind the ch9.h
Uploading file to Arduino worked.
now i am getting the “OSCOKIRQ failed to assert” error.
Hello Oleg,
in your examples you often use “qep_port.h”. Which library must I include to get the required files?
Thank you
Martin
It’s explained here -> http://www.circuitsathome.com/mcu/arduino-based-controller-for-canon-eos-cameras
btw for those of you who have sparkfun board will need to edit the max3421e_constsnts.h file to have.
#define MAX_GPX 7
#define MAX_RESET 8
The fix to the Max3421e_constants.h file worked for me. I was previously getting the ‘OSCOKIRQ failed to assert’ error message.
Thanks
Hy,
I connected the Arduino mega now with the USB_Host shield.
But I am getting the “OSCOKIRQ failed to assert” error.
I mesured the crystal and the signal was ok. (sinewave with 4V peak to peak).
I do not undaerstand what the errornotice means.
Any ideas?
I managed to get a Arduino328.
I had to change the includes to run the USB_Desc sketch.
Now i have the descriptors.
Is it right, that i have to change something in the Wiiblue.pde
after /* CSR Bluetooth data taken from descriptors */ ?
The only difference to your example is the
VendorID
ProductID
RevisionID
What are they called in the Wiiblue sketch?
I guess VID is VendorID but what is CSR_VID_HI and _LO ?
You’re right.
Vendor ID –> CSR_VID_LO, CSR_VID_HI
Product ID –> CSR_PID_LO, CSR_PID_HI
Where the IDs are 2Bytes long, so high byte need to be set to _HI and low byte will be set to _LO.
Eg. when you got “Vendor ID: 0A12”, you set CSR_VID_LO=0x12 and CSR_VID_HI=0x0a.
thank you!!,
the programm “blueutils” worked now, and i was abel to connect my wiimote as hci device.
I tested the programm “wiiblue” to get sensor information from the wiimote.
But my programm makes no progress after “CSR Initialised”.
I actuelle wasnt able to get the same CSR BT-Stick as described on the website. So i bought any cheap dongl which has Rfcomm protocol aviable too.
Is that a problem in any way?, because in that programm only L2CAP layer is used.
Any idea why I can get the descriptors for any high speed device I plug in ( flash drives, etc), but nothing for any lower speed devices like a mouse?
I’m using the descriptor parser example and all I get is ‘Start’ when I plug in my mouse.
Thanks!
I double-checked descriptor parser with my usual set of devices, low and full-speed (one of them being USB 1.0) – everything seems to work fine. Which shield/Arduino variants are you using?
I’m using a sparkfun shield (the updated version) with a UNO. Any suggestion of what I should be looking for?
I verified the the power supplied by the shield to the USB devices and I noticed that it was only 3.3V… Connecting a 9V power supply to the Arduino (as opposed to powering the Arduino from USB) took care of this issue. I can now get the descriptor for my mouse!
Thanks for all the work on the design and libraries!
Regards!
Thank you for sharing your finding!
I have an arduino nano v3, and the mini usb host board from circuits@home. I am using 3.3v-5v logic converters. It is wired exactly how the coding in max3421e_constrants.h calls for. powered via regulated 3.3v.
running board_test results in “Error: OSCOKIRQ failed to assert”
all wires checked – new code downloaded – no spi library, as instructed. compiles with out errors. error persists.
Ideas? Thanks in advance!

Does SPI test in board_test run without errors? You can skip GPIO test by pressing any key.
I was testing in arduino IDE – and commented out some of the tests to isolate the SPI long test.
still fails
Hi, I have a SparkFun USB shield with arduino duemilanove, I get the error: <> , I tried to change #define MAX_GPX 7
#define MAX_RESET 8, and nothing happens. The arduino is external powered, If I try to make many resets, sometimes it works without error, and I was able to see that touching pins near gnd,5V,3.3v if I push in that zone with a finger, it works and start without errors (quite weird, no?). At this point I thing it might be something related the power I egt into? I run the arduino with external 12V power… am I doing it wrong?
I menat I get the Error: OSCOKIRQ failed to assert
I meant I get the Error: OSCOKIRQ failed to assert
Hi, I have the latest Circuits@Home host shield and I am running the board_test program on a Duemilanove (328p). I have a 9v supply from an AC adaptor and I am able to check that the 5v and 3.3v are present on the headers with the USB jack not plugged in (so it is clearly getting the power from the adaptor).
I can’t get past the OSCOKIRQ assert error when the line Max.powerOn() is executed. After that the board hangs. I am running with the stock settings and I downloaded the library recently (file dates show Feb 24).
Any help greatly appreciated!
Do you have all included headers soldered in place? Also check that they mate with Duemilanove connectors properly.
I’ve soldered all the headers. Eyeballing it and feeling the headers, it seems the connections are good. I tested for continuity for the ICSP pins and digital pins 9 and 10 with the Arduino solder joints. What else should I test for? I am running on Arduino 22 IDE on a Max OS X. The shield version is dated Dec 2010. Thanks for your help.
What kind of testing equipment do you have access to? Also, how far does the board_test go – can you see anything past “OSCOKIRQ failed to assert” message?
I could borrow a friend’s scope. The board_test doesn’t go further than the assert message. I could add prints to see where it stops within the powerOn method if that will help. When I commented the powerOn call, it failed with a “Reading REVISION register…Die revision invalid. Value returned: 00”.
if you comment out powerOn(), you’ll break MAX3421E initialization – by default, it operates in half-duplex SPI and SPI routines in the code are written fro full-duplex SPI. There is only one place in powerON() which may loop forever – it is line 215,
while(!(regRd( rHCTL ) & bmSAMPLEBUS ));. Comment out this line and see what happens.Most likely, SPI is not working correctly. If you can get a scope, take a look at this article -> http://www.circuitsathome.com/mcu/arduino/usb-shield/troubleshooting-arduino-usb-host-shield to see how proper SPI signals should look like. Also, if you can, check the shield with another Arduino board.
I am going to check the soldering again. I suspect there is a bad connection. It can’t read anything, basically regRd() is reading 0 when I try printing the output of regRd(rPINCTL). I’ll let you know. Thanks again.
That was it!! A bad connection (actually my miserable soldering skills). The board test passed. Thanks for the help, Oleg! On to making the Duemilanove talk to a Nook using ADB.
Hi,
I just bought the SF USB Host Shield (http://www.sparkfun.com/products/9947)
When I tried to execute the board test sample I got the following error :
Error: OSCOKIRQ failed to assert
Circuits At Home 2010

Press any key to continue…
Reading REVISION register…Die revision invalid. Value returned: 00
Test FAILED*!*

I’am using USB Host library downloaded with the name felis-USBHostShield-a59ba5b.zip.
I tried to change MAX_GPX and MAX_RESET to #define MAX_GPX 7 #define MAX_RESET 8 but problem still persists.
I use an ATMEGA 2560 + USB and an external +9V power supply.
(SPI pins are correctly connected according to atmega2560 specification)
Thanks for your help !
I get this error:

I am using the Circuits@Home USB Host Shield Rev. 2 date 07 Dec 2010 with an Uno
Any Thoughts on what it maybe?
Do you have all headers soldered on, including 2×3 ICSP header?
I’m getting this same error on my Arduino Ethernet R3. I also have a Arduino Uno R3. The Uno is working fine, but I’m getting the error with the Ethernet. I have soldered the SS connector over to pin 8 and cut the connection on port 10. I also updated the software to us pin 8. That seems to be working on the Uno. Any help would be great, working on a project that needs ethernet.
Take a look at this, could be helpful -> http://www.circuitsathome.com/mcu/running-multiple-slave-devices-on-arduino-spi-bus
No I have just the “Shield” headers attached… the my brain just went….. Ahhhhhhhh…
Thanks!
it is up thanks!
Whenever I try to upload the PS3BT sketch to my Mega2560, I get an error that says “‘USB’ does not name a type”. What’s happening here?
You have properly not included the library properly. Please read: https://github.com/felis/USB_Host_Shield_2.0#how-to-include-the-library.
I am getting an error on running board_qc. Using Sparkfun latest USB HOST Shield and Code from USB_Host_Shield_2.0 by felis.

Please use the official shield in order to support the actual developers of the shield and library!
i’m using example from USB host library and get this error
