Because I used to play with the Ink Screen Weather Station, I had a large number of disassembled MSP430G2553 left over, so I made this voltage and ammeter.
Software development environment IARfor430-7.11 version
The program source code is placed in the attachment. Currently, it only has basic functions of reading and displaying, with reserved wake-up buttons and setting plus and minus buttons.
The cost of this voltage and ammeter is extremely low, only the price of an OLED screen and ina226.
The recommended board thickness is 1.0 to 1.2, and the top one can protect the screen.
