Part Number: TMS320F28335
Other Parts Discussed in Thread: ISO3082
Hello
I got a question in related to serial port application.
I am using SCIRXDC (pin 113) and SCITXDC (pin 114) to establish a RS485 serial communication.
On the hardware side, I have TI ISO3082 half-duplex RS485 transceiver. Hardware has been verified.
I set up a “data buffer” in the code to store the message. The master of RS485 is my PC software. The slaver is the control board.
The problem I have is kinds of odd.
When I reset the DSP CPU through CCS v5.5 debug, sometimes the buffer can be filled up with data.
Sometimes, it cannot.
In a word, the 485 communication is “intermittently” working when I reset the DSP CPU.
Wonder some “registers” associated with SCI C channel may cause this issue... This part of code may be missing.
Any thought is greatly appreciated!
