fast serialUSB read function readBlock
Moved from https://github.com/arduino/Arduino/pull/4871
sined23 commented on 15 Apr 2016 The main idea is that bytes are written and read into/from CDC buffer not one by one but block of bytes.
Serial_::accept write into CDC buffer as maximum as possible (only to not overflow the buffer) Serial_::readb (you can change just read, not use readb) get from CDC buffer as maximum as possible or nessasary length
and one more important thing: in USBD_Recv "while (n--) *dst++ = UDD_Recv8(ep & 0xF);" should be replaced into UDD_Recv(ep & 0xF, dst, len);
Hi, I have merged this code into my own code from Arduino IDE 1.8.9 and I can confirm the code merges properly. I am testing this code using and Arduino DUE and I can confirm that it works correctly. Is it possible to merge this tot he latest base?
