Hi,
i am using the spi1 overlay like this.
My spi bus where it is connected is 1 and the CS 0. The INTA is connected to GPIO16.When i check now my pins with pinctrl it says that the Clockselect are output pins instead of the CE0.
What can i do that they are marked as ALT4
My GPIO Expander MCP23S18 is working with the inputs and the Interrupt pin GPIO16, but i didn't manage yet to write to the outputs and i think it has something to do with this.
I am using the the API diozero for controlling the spi bus and the inputs and outputs.
Furthermore my ADS1118 is also not working on CS1. Here i am using pi4j2 library for connecting via SPI, but it has the same result.
Thanks for your help.
