Endpoint bulk in jb 16.

fredycolombia — Mon, 11 Feb 2008 11:25:31 GMT

Hi,

I have used testhid in jb16 to sending any data through usb interface.
I only put dato=PTA, and then I put it on KbBuffer[0]=dato. The problem is that the data mean rate is to slow (2Kbytes/s) and I need to increment data rate.

Now I burn TBDML_JB16 and windows recognize like "USB DEVICE" , I have used usbio driver and this identify endpoint like bulk. I want to send it data through usb without use bdm in this firmware, but I don't know where I can put "dato" or how to do the same as in testhid to send any data through usb.

I attach firmwares and images about my problem. I appreciate your help.

regards
Fredy.

You need to change bInterval in the endpoint descriptor.
- descriptor's bInterval value indicates the requested maximum number of milliseconds between transactions.

I highly recommend you get a JM60 Demo board and go with that. The generic hid demo pumps data quite well and the CDC demo work at 115K baud.

Hi jim,

Thanks for answer, I have already JM60, and I agree with your suggestion, I think is a good mcu to use usb.

regards,
fredy
