i downloaded an older firmware to my Omega...0.3.2 b230 and this was resolved. The build number of the kernel in this firmware matches what was available

Ok since my device was available in the /dev/ folder as spidev1.0...given I assigned bus0 and deviceid 1 when I ran insmod...I was able to use the standard spidev library in Python to access this newly created spi device. The CS now goes low when I run my python script but I don't see any data or clock signals...I'll check for a conflict with the pins that I assigned to MISO, MOSI and SCK. Will report back soon, if this works...then it's actually easy to implement software SPI.

Hi,everyone. I'm working on a project where I need to connect a chip that works over SPI .I used raspberry pi 4 and Ic ad5422 in my project. now I want to send data throw spidev and xfer that my data is 24 bits. The input shift register is 24 bits wide. Data is loaded into the device MSB first as a 24-bit word under the control of a serial clock input, SCLK. Data is clocked in on the rising edge of SCLK. The input register consists of eight address bits and 16 data bits. The 24-bit word is unconditionally latched on the rising edge of the LATCH pin. Am I using spi.xfer3([0xab, 0xcd,0xef], 3) in my code? Does anyone know what am I doing?

thanks for pointing out, i just ordered the expansion dock...I was using the power dock. I'll report back if this fixes it...hopefully my troubles can at least benefit someone else

maybe pip3?
