MCP3201 Module

This module contains the driver for Microchip MCP3201 analog to digital converter with SPI serial interface (datasheet).

Example:

from microchip.mcp3201 import mcp3201

...

mcp = mcp3201.MCP3201(SPI0, D17)
value = mcp.get_raw_data()

MCP3201 class

class MCP3201(spidrv, cs, clk = 400000)

Creates an instance of the MCP3201 class.

Parameters:

• spidrv – SPI Bus used ‘(SPI0, ...)’
• cs – Chip select pin
• clk – Clock speed, default 400 kHz

get_raw_data()

Return the conversion result as an integer between 0 and 4095 (12 bit). The digital output code is determined by the reference voltage Vref and the analog input voltage Vin:

Digital output code = 4096 * Vin / Vref
