Sharing a SpiDriver between multiple Devices with different configs

[agmes4]

Im currently trying to get multiple SpiDeviceDrivers out of SpiDriver cause the devices have different configs. Borrowing worked for compiling but all the time I try to create the second DeviceDriver the esp get stuck in execution.

Is there first an easy way to share to share a SpiBus here with out these issues and is there additional documentation for such cases?
I tryed

let mut spi_device_driver =
        SpiBusDriver::new(&mut spi, &config).expect("Failed to init spi flash!");
spi_device_driver.write(b"as");
spi_device_driver.write(b"as");
spi_device_driver.write(b"as");
spi_device_driver.write(b"as");
spi_device_driver.write(b"as");
info!("have send");
let config = config::Config::new()
        .baudrate(4000000.into())
        .bit_order(config::BitOrder::MsbFirst)
        .write_only(true)
        .input_delay_ns(0)
        .data_mode(MODE_0);
    
let mut spi_device_driver2 =
        SpiBusDriver::new(&mut spi, &config).expect("Failed to init spi flash!");
spi_device_driver2.write(b"as");

not using a SpiBusDriver but directly creating multiple SpiDevice instance's with different configs for each? You can have a look at the loopback example where we create two SpiDeviceDrivers with two different clock speeds.

the Problem here is that my display needs to have a minor delay between 2 bytes what I do in the device via manually pulling the CS to high and the later again to low. I think I found a way by passing Option::::None as cs it is possible to create without setting a pin thanks.

is this thread safe this way and can use this in different task each for a spi device?

[Vollbrecht]

you can have SpiDeviceDriver A in thread A and SpiDeviceDriver B in thread B yes. Though if you want to share SpiDeviceDriver A in thread A and B you have to lock that yourself.
