Raspberry controller with dual analog outputs, single analog input and digital I/O. Ver 1.0

We are looking for controller software for a Raspberry based multiple controller system.

Controller environment consists of:

1. Raspberry Pi 4B 4Gb controller with touch screen LCD, keyboard, mouse (and wifi).

2. High Precision AD/DA expansion board and Relay Expansion boards (2).

Functional Specifications. Detailed flow chart to be provided to selected Ffeelancer:

3. LCD to display 16 different parameters, with titles for each parameter.

4. Ten of the parameters are set up by the user via the LCD.

5. The program can dynamically change any of the values displayed

6. There are 2 analog outputs which are set by the user via the LCD

7. There is an analog input which controls the 2 analog output voltages, but the ratio of the 2 analog outputs in maintained, even as the values of the outputs change up or down to follow the analog input.

8. Digital counter input (low frequency pulse input with max of 3 pulses per sec.)

9. Multiple of these controllers, with all connected to the network by WiFi or Ethernet cable.

10. Every controller can be monitored or set up from a master Raspberry 4B controller.
