I have a small board that has 2 devices attached to the same SPI bus
* AD9833 DDS that uses SPI MODE 2
* MCP41010 Digital Potentiometer that can use SPI MODE 0 or MODE 3
Each device has its own C…

### The problem
While trying to configure a SPI bus on an ESP32S2 using the Arduino framework the build fails due to VSPI not being defined for this platform. For ESP32S2 and ESP32S3 FSPI needs to be…

Are there any plans to add SPI support for communicating with your short-range devices (e.g. NINA-W156)? Maybe there is another library that uBlox has to already support this?
Thanks :)

Is there a canonical way to share SPI devices that are on the same bus using `embedded-hal-bus`?
All variants of shared SPI devices seem to follow a pattern like this:
- create a SPI bus
- wrap…

As long as I'm only accessing ONE SPI device everything is fine, but when accessing TWO (in my case: MFRC522.py for two RFID-Readers) only one of them works. Looking at your code I think the problem i…

Hi @ebezine ,
I'm experiencing conflicts using two spi devices (share violation on gpio...).
The first one is an MCP3008, while the second one is a Nokia3310 lcd display.
I managed to run both with …

Is there any way to use this to drive multiple displays?
In theory you could drive 4 displays with an ESP32 directly (2x i2c, 2x addresses).
Thanks for your help :)

This is a followup on #8642
If a method was provided to detect if the bus was already initialized a decision could be made on calling `spi_bus_free` before reinitializing. In my situation I have a d…
