USB / Re: K64F usb host won't build
« on: January 23, 2018, 07:03:29 PM »
Hello Mark,
Thank you for the quick reply.
I have been working on this for a while. I am trying to communicate with a USB CDC device. The device in question is based on an ATMEGA32U4 chip and works correctly using a PC.
In the past, I managed to get it to work using a teensy 3.6 board.
I wanted to add network communication to my project, so I bought a FRDM-K66F board because it basically has the same chip on (only flash size is different I think) and has a Ethernet socket an phy on board. The only difference that i did not notice was that the USB was routed to the HSUSB instead of the FS one, so i could not use the same librarie and i would have to rely on the NXP USB libraries. But all NXP USB libraries I have used so far have not been able to talk to my USB device. The device enumerates correctly, but stops responding after the first caracter is sent to it.
After seeing you video on youtube i was hopefull i could replicate it with the K66F board and switch my project to a uTasker project.
Perhaps i could source a K64F board to test with utasker, would i be able to configer utasker as a USB CDC host in FS mode to see if i can manage to talk to my device?
