AWR2243: Monitor the Chirp start signal through GPIO

Wang Qiyu
Intellectual 260 points
Part Number: AWR2243

I plan to monitor the Chirp start signal at the beginning of every chirp, 

is it possible that AWR2243 generate  this Chirp interrupt output through GPIO?

    Hi,

    The AWR2243 will behave like a black box to user. You can only communicate to it via SPI communication and use the mmWave link APIs to communicate with it. There is no direct way of generating a chirp interrupt O/P through GPIO. 

    The 2243 provides the ADC data packets (over CSI2) which will have similar timings like Chirp start and chirp end. So you can use that in your application. 

    Also can you let us know the use case for this so that we can check this internally with the team to provide you with more feasible solutions or alternatives.

    Thanks,

    Pradipta.
