Hi guys I have sorted out the communication between a PC _ USB TTL and raspberry pi onboard TTL serial port, I'm able to send and receive data ( hex or ASCII).
The Receiving side on the raspberry is tricky, I dont get all the data bytes in one PLC cycle all the time . Using CAA Serial Library , if I use some example projects from pixend or others using the receiving bytes converted to ASCII, basically I receive 2 or 3 strings instead of one .
Is there a solution for this ?
Any ideas or projects to share will be more then welcome guys.
