I2C_transfer call in Swi context

Mikhail Dokorin

I need to write I2C DAC value periodically. I use clock SWI to do it and it is blocked in I2C_transfer call (callback mode). Is callback mode supported in the execution context of Swis and Hwis ?

Hi Mikhail,

I2C_transfer should only be called from Task context. It uses a semaphore as a lock internally and therefore has potential to block.

Best,
Ashish
