CSNS setting and Control of HSD pinouts with SPI

peaces — Wed, 02 Jun 2021 14:57:28 GMT

Hello everyone,

I am trying to make SPI adjustments according to the datasheet of the IC we used (MC15XS3400), but I cannot control the outputs and I cannot see any data flow when I trigger the HSD_IN0 pin from outside.

Hello @peaces ,

Unfortunately, I don't have access to the board so I cannot test the code attached.

I would try to control the HSD via the SPI protocol first. For that, I've tried the following model to control the outputs.

at first, it will control the Reset Pin, will send the PWM control command, and after that will toggle the OUT0

This is how the set HIGH command looks like:

Please give this model a try, but be aware that it sets the output fully open and at every second fully closed.

Hope this helps,

Marius
