Hi Martin
You did not use the SPI Master component.
Is the next step?
MCP320x 16-bit to Nano

Re: MCP320x 16-bit to Nano
Just tested the above bit-bang code with an Arduino (Uno) - and seems to work okay.
With a VRef (and VDD) set at 5V and IN+ and IN- connected to a PSU (I also tried connecting IN- to GND) - I got reasonable results. For example - with the PSU set to 3V - 2.987V was output to UART.
I connected the pins to the logic analyser - and again the output seems reasonable.
0 - is CLK, 1 is Data and 2 is CS. The MCP3201 seems to take a moment to shutdown after CS returns high...
