solved: HIDKeys + ATMEGA16

Post by TheDude » Wed Nov 16, 2011 10:25 pm

Hi folks,

I'm in desperate need for some assistance as I spent hours trying to get the HIDKeys to work on some MJoy16 hardware I had lying around. This is a firmware only joystick device, which is closed source and built according to this schematic: http://www.joysticks.ru/download/files/MJoy16_v1.pdf. The hardware works, when flashed with the closed source firmware I have a working joystick device.

Now for the changes I made to the HIDKeys example:

usbconfig.h:
no changes

main.c:

Code: Select all

static void hardwareInit(void)
{
uchar   i, j;

    PORTB = 0xff;   /* activate all pull-ups */
    DDRB = 0;       /* all pins input */
    PORTC = 0xff;   /* activate all pull-ups */
    DDRC = 0;       /* all pins input */
    PORTD = 0xfa;   /* 1111 1010 bin: activate pull-ups except on USB lines */
    DDRD = 0x07;    /* 0000 0111 bin: all pins input except USB (-> USB reset) */
   j = 0;
   while(--j){     /* USB Reset by device only required on Watchdog Reset */
      i = 0;
      while(--i); /* delay >10ms for USB reset */
   }
    DDRD = 0;    /* 0000 0000 bin: remove USB reset condition */
    /* configure timer 0 for a rate of 12M/(1024 * 256) = 45.78 Hz (~22ms) */
    TCCR0 = 5;      /* timer 0 prescaler: 1024 */
}

changed the second DDRD call from 0x02 to 0, because the D+ line is also connected to PD1 in my hardware. I don't want that pin to drive that line, so I set it to input (0).

Code: Select all

int   main(void){

uchar   key, lastKey = 0, keyDidChange = 0;
uchar   idleCounter = 0;

   //wdt_enable(WDTO_2S);
   wdt_disable();
       hardwareInit();
   //odDebugInit();
   usbInit();
   sei();
       //DBG1(0x00, 0, 0);
   for(;;){   /* main event loop */
      //wdt_reset();
      usbPoll();
      
         [...]


disabled all the watchdog timer calls, as I'm not a friend of watchdogs during development, even included a wdt_disable()-call. Also disabled the debugs.

Makefile:

Code: Select all

COMPILE = avr-gcc -Wall -Iusbdrv -I. -mmcu=atmega16 #-DDEBUG_LEVEL=1

set AVR type to ATMEGA16 and disabled size optimisation, thought this might help. But same result with optimisation.

Other than that everything is "as shipped"

my fusebits are:
high: 0b10001001
low: 0b10011111

and my problem: well, "unable to enumerate USB device at port 1"
I'm new to USB so the usbmon logs don't really tell me anything, maybe they are of help to you:

( a bit lengthy)
I also used wireshark, hoping that it might be a bit clearer to me what is (not) happening. Ah, well, it says "malformed packet" in the GET_DESCRIPTOR response. Now what?

So, could anyone pleeeeaaase help me? What am I doing wrong? I spent days fiddling around with this, thinking "it can't be that hard", well, mistaken.
I hope you have all the info you need.
THX folks


edit: SOLVED
problem was the pin setup. As PD1 is also connected to PD2 I had to set PD1 to input and disable the pull-up as it is done with the USB line. This war PD1 does not accidentally drive a USB line.

Make sure you have F_CPU defined as 12000000 because of your 12Mhz crystal.
In the main loop, only call usbPoll(); for now, until it works.
Use a known working descriptor. I always use the hid-mouse example to test new v-usb hardware.
Make sure your pin configuration matches (usbconfig.h), because the hardware you linked doesn't match the reference design of using PD2 and PD3.

FYI: Your computer will try to enumerate the device even without any firmware in the controller. This is due to the pullup on D-
