Posted on February 04, 2014 at 16:14I am attempting to get the CPAL I2C library to work with an STM32F407. In the DMA TC ISR handler, the code checks for the BTF flag to be set before sending the stop condition. The problem is that the BTF flag never gets set. I looked and there is no acknowledge failure.
Any ideas as to why this is?
