I have a Teensy 3.1 project using two UARTs. One is 3.3 V TTL to a 3rd party product and the other is RS485 (with transceiver) to a windows pc with a USB/RS4855 convertor.
I've seen it work almost flawlessly, but not quite perfectly, and now it's not working so well. It could be a mix of software and hardware problems.
There is a large amount of data coming from the TTL UART and I'm not sure the RTS is working correctly. I have modified the core file "serial1.c" to use a larger buffer
#define RX_BUFFER_SIZE 4352 // was 64
I'm in southwest Austin, TX (Oak Hill actually) and am looking for someone who could look at the hardware, or at least do some remote access.
If anyone is interested, please let me know at jschindler at austinai dot com
Thanks,
John
