Design a microcontroller circuit which will communicate with another system via rs232 communications with adjustable communications speeds. 32kb is the target communication speed. The circuit will read and debounce 64 5volt inputs and transmit the data out via serial port. The circuit will then receive data from the serial port and latch it to led driver outputs (32). The system will also read 4 analog inputs, and write 4 analog outputs. (0 to 5v) Processor is up to you, pending our approval. A working pcb would be ideal. SMT is not required. PCB Headers can be specified later. The system will function to read and display operator switch selections on a CNC machine interface. Discrete inputs and outputs are required, not a matrix.

I have expertise in serial communication using the RS232. Based on your requirements for so many non-multiplexed discrete input switched and output leds, an ideal processor would be a CPLD. I have enough expertise in working with input/output using GPIO based on bit-banging

Hi, I have already developed similar kind of data acquisition system to monitor railway signaling. This can be easily design using PIC controller in a cost effective manner. I would like to discuss with you in details. Please inform me if you are interested.
