Low-cost multi-channel digital multimeter using PSoC 4/5.
This project is intended to constantly monitor/ plot one or more voltage, capcacitance , resistance, current.
Currently only supports DC voltage upto 5V and Capacitance in pF.
- Windows XP/7/10 and everything in between
- PSoC Programmer http://www.cypress.com/file/410636/download
- Python 2.7
- PSoC creator(if you want to edit the source, which is recomended)
CY8CKIT-043 is used here as it cheap and readily available, but it can be modified for any Cypress Kit.
PSoC programmer provides COM that can be used with win32com API in python. This also gives python the ability to directly talk to the MCU over I2C/SPI/UART.
