SPI Core

I am using the SPI core in 7.2sp2 - I have a device (ADC128S102) which reads back data in the same 16 bit transmission as the command is sent. The chip is working fine - I can select the ADC channel ...

Thank you!

I figured that was pretty much what I needed to do. I started out using the Altera HAL drivers, but very quickly found a couple of issues:

1.. The HAL driver only supports 8 bit transfers as supplied - although adapting it for the 16 bit transfers I need was not difficult.

2.. It is not designed for simultaneous transfers - which is a very common requirement on SPI interfaces. Once I took the time to understand how the driver was working the solution was rather obvious!

Again, thank you.
