Other Parts Discussed in Thread: C2000WARE
Using C2000Ware example codes, we implemented some full duplex RS422 and RS232 protocols that employs Interrupt and FIFO to minimize microcontroller load and improve response time.
For RS485 case I can not figure out how to efficiently handle the port direction pin that is connected to a GPIO with minimum microcontroller load when interrupt and FIFO are enabled for SCI interface.
- Is there any feature in SCI interface to automatically handle RS485 direction?
- Is there any software trick or technic to do that while FIFO and interrupt are enabled without polling TXEMPTY flag?
With regards,
