18f4550 clock settings to get usb running?
Posted: Thu May 21, 2015 3:31 pm
When i try to develop anything on the 18f4550 it seems that almost all times my computer feels that the "usb device connected did not report correct header"...
Im using the 19.999MHZ clock, tried 4MHZ and 8MHz, 12Mhz and 16Mhz... No luck here.
When im looking at the clock settings of datasheet and then the flowcode, i feel like im kid in candyshop, i cannot decide settings that SHOULD work. And when im done, the "send config now" button is gray all times not depending on the "download config on program load" thing..
Could anyone explain those settings or even make some kind FC6 wiki article on it? Simple explained flowcode files are too welcome!
The USB macro wiki is almost all times depending on ECIO or something other "ready to run" , not real MCU:s have been used to explain anything.
Been trying to play with CAN bus and USB together, but seems like this is never gonna work at the moment.
