Labview Arduino SPI and MCP2210 evaluation board

[JP67]

Hello, I'm trying to communicate in SPI with Arduino via Labview. I have loaded LIFA and the latest LINX toolbox in LabVIEW 2013.

I am exercizing myself with the MCP2210 evaluation board with 2 components : Temperature measurment with TC77 and driving leds with MCP23S08 I/O expander.

I succeed to read the TC77 (with some errors), but I can't write correctly the 8 leds which can be driven by the MCP23S08.

I have the good signals on the oscilloscope (GP4 which I use for CS, MOSI and SCK.

The leds bright (or not) with a quite puzzling manner.

I have some question in understanding the differences between SPI Channel(0) and CS Channel.

Could you help me ?

The image you posted does not use LIFA.  It uses LINX.  For LINX support, you should post on the LINX forums.

I use LINX because I don't succed to do the same function with LIFA.

Thanks.
