Hi
I have been looking and looking but cant really find in any good info on exactly how to do this. Basically I have a serial servo setup the only accepts baud 4800 8bit byte strings. Essentially there are multiple servos daisy chained along one serial line that sends the string down the line and each servo positions itself based off of the specific byte that is was preprogrammed to read from. Now what I am trying to do is instruct my arduino to output a test string down the serial line to set the servo positions. I figure I would need to use a analog pin for this but I havent been able to find a library or example on how to do this. I am just wanting to send a string to set a position then a string a few seconds later to return the servos to their start position so I can test the servo positions. I know I have the thing wired correctly I just need I bit of help getting the thing to output. The pinout this thing uses is umm interesting
3.3vs servo
3.3v power for servo logic
tx serial line to send byte string
ground for both logic and servo power. I have the tx hooked up to digital pin 4 right now and I know it is all hooked up correctly as these servos are designed to stick to a zero position when not reading any input. The byte strings look like this 0x05 0x00 0x00 0x00 0x45 0x80 0x85 0xFF any help in pointing me in the right directions would be greatly appreciated.
Thanks Again.
