Program - RS485 communication between Raspberry Pi4 and devices based on PIC micro
Budget: $30 – $250 USD
RS485 communication between Raspberry Pi4 and devices based on PIC micro
Write a program/script to communicate from a Raspberry Pi4 to devices connected on the RS485 bus (USB with converter).
The devices are set to measure voltage from 1 to 60 volts dc
Each device measures 4 different voltages with a common GND
Several devices (up to 32) are all connected to an RS485 bus
A Raspberry Pi4 will run the program to:
• Assign the address to the device (on demand push button on the device)
• Get and output the measures from each device
• The program will be executed from an exec node in nodered and the output returned to the same.
Available documentation:
RS485 protocols and functions
Functioning program written in C which has been used for testing the system using another Pic micro.
Testing
A Teamviewer connection will be set to allow the coder to test his program.
