Hi,
I'm currently using the BBB to control a rover robot for a project at my
university. I'm currently having an issue using the UART file /dev/ttyOx to
write an array of characters to a smart servo using c/c++.
More specifically, I've opened the file using
fopen("/dev/ttyO2", "wb")
which should open it in binary mode. I've also tried the c++ equivalent
with
ofstream file("/dev/ttyO2", ios::out|ios::binary)
For the most part these have worked fine. I have been using the UART tool
for the PicKit 2 to verify what I've been receiving. But, despite having
opened the file in binary mode, if I try to write 0x0A it will still append
0x0D to form CRLF, or newline.
For example, if I create a character array:
char c[] = {0xFF,0xFF,0x0A,0x01,..}
This is seen on the UART tool:
FF FF 0D 0A 01 ...
If anyone knows a fix, or can offer any insight (should I be approaching it
incorrectly), I would greatly appreciate it.
