Communication: The 8 Servo Controller Board can communicate with any host that has a serial port interface. The format is 9600 baud, no parity, 8 data bits, 1 stop bit (9600,n,8,1)
The board does not have an RS232 to TTL converter, however that is good because you can communicate with other systems by simple inverted TTL logic. The PIC processor can handle standard RS232 levels directly with only the use of 22K current limiter on the Rx pin.
You must send the chip 3 data bytes: sync byte, motor/servo number, and motor position Sync Byte: always 255 Motor/Servo Number: 0 through 7 Motor Position: 1 through 254
You can use C / C++ of whatever you want to write the host program on a PC as long as your application uses the communication settings and protocol described above. For example, in Visual Basic, just use the MSComm object, open the serial port with the above settings and send the 3 byte command sequence - simple as that.
