Hi,
my new application will be:
- 1 master (AM335x Starter Kit (Linux OS))
- up to 16 slave processors (AVR 8-bit microcontrollers) on separate PCBs
- UART based communication, full-duplex RS485 (C application, serial driver, from user space in Linux)
Master will poll slave processors for fresh data. Baudrate will be about 1 Mbps, each slave must be polled every 55 ms. Length of data packets will be 10 - 30 bytes.
I would like to know:
- what is the maximum possible baudrate
- what is a typical/maximum latency (TX->RX loopback connection)
Any other suggestion, how to comunicate with 16 slaves from embedded Linux?
Thanks,
Edo
