Regarding the C2000 blockset, how would I have one SPI block transmit right after another SPI block?

Hello all,

I need to send 32 bits of data to an external DAC via a microcontroller. The SPI blocks given in the C2000 blockset can only send a maximum of 16 bits. How would I go about sending 16 bits of data right after another 16 bits of data without the CS going high in between.

Thank you in advance.

You could try setting CS to low and high respectively, before and after [16,16] bit SPI transmission using GPIO.

Hello Andrew,

It seems like you want to send multiple SPI blocks over the same module.

Here is the link to the similar MATLAB Answer which I believe would help you to guide through the required steps:

I hope this helps!
