Motor controller that communicates via Modbus over RS232. We want to make a simple battery meter by getting the values of state of charge on the motor controller. This is to be graphically represented as a battery meter energy on the OLED display. You will need to use MODBUS related libraries for Arduino and the Adafruit OLED display driver / libary for the OLED display. We are using the WEMOS with OLED display.

Hi, I have lots of experience with embedded software development and can help you with this project. Please send more information on the project specification. Do I understand correctly that you have a motor controller and you'd like to develop a device which presents battery charge information on the OLED display? Does the motor controller has a battery measurement circuit and this information is available via Modbus commands? Please send specification for these commands. What do you expect from graphical battery meter representation? Are numeric value and a bar graph sufficient? Once I have these details I'll update my proposal. Kind regards, Krzysztof

Hello As I understand battery status should be displayed as timechart of battery level. I already worked with Adafruit OLED and WeMos and have this so I can show working PoC. Have never worked with ModBus over RS232, but it should not be a problem because I have experience with other data interface but wireless - NRF24L01. I can start work with your project from evening of Thursday and can finish it in 4 days maximum. Best regards
