CC2652R: Add communication between CC2652R and C2000

Part Number: CC2652R
Other Parts Discussed in Thread: LAUNCHXL-CC26X2R1

I want to realize a bidirectional communication channel between 2 MCUs (using exactly LAUNCHXL-CC26x2R1 and LaunchPad F28379D)

What is the recommended protocol to be used for that ? (I see the PMBus SW library available on C2000 for example); is it a good choice ? is this library available for the CC26x2R1 ?
My channel will be used to send to F28397D signals that will be next sent(/received) by CAN communication (every 100ms, a 500kBauds CAN not charged by more than 30% of load).

Hi,
I don't think we have a PMBus lib for CC26xx products. A suitable approach would be to write a communication protocol using I2C.

Hi,

And why do you advice to use I2C communication ? why do you advice I2C and not SPI or UART communication ?

Hi,
I suggested I2C because I believe PMBus uses I2C at the physical layer level(correct me if i am wrong) and you might be able to leverage code from PMBus library to implement it. You can very well use SPI or UART as well.
