Can anyone tell me why setting USB_CFG_HAVE_INTRIN_ENDPOINT3 to 0 gives the below warnings? I'm also told the compile failed but I have no errors? I do not use a 3rd but it had to be set to 1 to ovoid this crazy what not. is it needed because I use an out pipe? note: some warnings do not apply. Warn...

ok well this is how I would do it but yes you would loose 8 ms here. EDIT : ( ok I see you are doing this here gamepad_report_1.report_id=1; ) then see comment below. usbSendHidReport((void *)&gamepad_report_1, sizeof(gamepad_report_1), 1); usbSendHidReport((void *)&gamepad_report_1, sizeof(...

Ok well I downloaded you files and you didnt have the set to 1? Update your zip file so we can help you better. btw: you dont see to use ENDPOINT3 to do this? All you need to do is change the report id in your out going packets. Is there a reason you are trying to do this on its own pipe? Speed mayb...

You didnt set the 3rd enpoint in config? #define USB_CFG_HAVE_INTRIN_ENDPOINT3 0 /* Define this to 1 if you want to compile a version with three endpoints: The * default control endpoint 0, an interrupt-in endpoint 3 (or the number * configured below) and a catch-all default interrupt-in endpoint as...

I'm confused by "Code is compiling without errors." do you mean the suggestion fixed the issue, or just that it compiles and you still have the endless loop?

If you have one endpoint and the default use usbSetInterrupt()
If you have two endpoint and the default use usbSetInterrupt3()

sorry I dont recall what usbFunctionInterrupt was for i'll report back if I recall.

your not polling? while (!usbInterruptIsReady()) usbPoll(); usbSendHidReport((void *)&gamepad_report_1, sizeof(gamepad_report_1)); while (!usbInterrup3tIsReady()) usbPoll(); //just a guess on the name here usbInterrup3tIsReady may not be the right name. usbSendHidReport3((void *)&gamepad_rep...

I think d+ needs to go to an int pin. Other then that they should work on any pin. see in code Please note that D+ must also be connected * to interrupt pin INT0! # define USB_CFG_IOPORTNAME D /* This is the port where the USB bus is connected. When you configure it to * "B", the registers...

I'm after the same thing http://forums.obdev.at/viewtopic.php?f=8&t=8493 From the SO page I think he is claiming that he stole more bandwidth from one of the pipes. I will look in to that but I dont think its possible with v-usb. I think his reference to set_report is just setting the report typ...

I think v-usb just uses the interrupts for timing and the poll depends strictly on the function usbInterruptIsReady.

1) guessing the buttons and Encoder are input you want to send to the host and you need the host to turn on your device leds? Normally to commune from host to device you need to use the vender specific feature. I never used that before but it requires a driver. For the descriptor I'd use the HID gam...

Ok just saw something in my code I didnt see the first go. I'm set to 10 in config but I my descriptor I have this USBDESCR_ENDPOINT, /* descriptor type = endpoint */ //0x81, /* IN endpoint number 1 */ 0x81, // bulk IN endpoint number 1 0x03, /* attrib: Interrupt endpoint */ 8, 0, /* maximum packet ...

Trying to tweak poll timing a bit here. I'm set to 10ms in config So I normally do this while (!usbInterruptIsReady()){usbPoll(); } usbSetInterrupt((void *)&reportBuffer + 0, ; while (!usbInterruptIsReady()){usbPoll(); } usbSetInterrupt((void *)&reportBuffer + 8, 5); If I do it one like whil...

I was looking for a software solution using a watchdog or something.

yeah that is because your data reader needs calibrating.

example

reportBuffer[1]= (read_adc(0)/3 + 200);//pc0 : this is some extreme math

You have to now do your own math. Maybe just - 50 from the result ( only a guess ) you'll get it.
