Until you find that out, you will have great trouble driving it. The MCP23017 is an I2C enabled 16 I/O port chip. The MCP446X family is available with end-to-end resistor values of 5 KΩ, 10. Small Slider Image - I2C RTCC, SRAM, TSSOP-8 MICROCHIP MCP7940M-I. The MCP23016 can be controlled by a 2 wire I2C connection from requestFrom(B00100000, 1); //ask only 1 byte from the MCP with id 0x20. MCP23017(i2c, 0x20) # list interface . I/O expanders provide a simple solution when additional I/Os are needed for ACPI, power switches, sensors, push buttons, LEDs and so on. Use readGPIO (1); to read port B. Microchip Technology MCP47CMB02-E/MG. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard). You should see the the values for hot junction, cold junction and ADC. Arduino Library for MCP23XXX I2C and SPI GPIO port expanders. from machine import Pin, I2C import mcp23017 i2c = I2C(scl=Pin(22), sda=Pin(21)) mcp = mcp23017. The MCP9600 is a fully integrated thermocouple Electromotive Force (EMF) to degree Celsius converter with integrated Cold-Junction compensation.
