I need a circuit which contains a microcontroller and which has ten optocoupled inputs and a precision of 1ppm
-Microchip or Atmel controller
-10 optocoupled inputs for normal switches
-Input voltage: 12 Volt
-1ppm precision with TCXO or something like this.
-2,54mm header for the connections (10 inputs, Power supply, RS232 signal)
-Header for flashing the microcontroller
-An precise interrupt should be generated when one input is switched
-Timestamp is generated and the following message is send through RS232: Number of input (1...9) / Timestamp
-The last input should be used to reset the timestamp to zero
-Timestamp is in milliseconds
Design should be made with Eagle or Kicad and the software code should be provided as well from you.
