i have 2 simple question:
how can acces endpoint buffer for read and write and send manualy ?(for exmple I wanna set a buffer to tranmit to host)
in FX3 and in bulk I can not find any pointer etc. to a buffer !
For sending your own buffer order or bytes you need to use Manual DMA configuration instead of AUTO DMA configuration. This Manual DMA has a Callback function through which you can send buffers to host pc or receive data from host PC. For further doubts see AN65974 Slave FIFO Document's Manual DMA Configuration Section.
