Hello all,

I am trying to implement a kind of RS232 filter using an SX28.

The SX28 should listen on RA0, accept a 38 byte array (shown below), then output only bytes 14 - 21 on RA1

RA0 receives the byte array every 1 second, at 57600 baud (TTL non-inverted). Output on RA1 should be the same.

1. I have the 4mhz and 50mhz external osc's, Which should I use?
2. Does any example code exist for serin / serout at 57600?
 
I am happy to experiment! But I could really appreciate some pointers. I have read lots on this forum, but there are samples for 9600 baud etc.. and talk of problems with byte arrays larger than 16, so before I flounder in at 57600, I would like to see if any samples or advices at this baud rate exist!

The sample byte array:
58 32 58 01 02 20 49 02 01 93 28 42 43 1f 04 9d 25 95 00 00 81 00 00 00 1b 33 50 a3 0d 20 50 50 00 00 28 0a 0d b7

First 3 bytes are fixed header
Last 3 bytes are always 0a, 0d then a checksum.


Best regards, Max.
