SPI clock polarity initalization in STM32 Cube L0

Posted on June 18, 2014 at 10:07I have a project based on the example found in STM32Cube_FW_L0_V1.0.0\Projects\STM32L053R8-Nucleo\Examples\SPI\SPI_FullDuplex_ComIT I have changed the initialization of   SpiHandle.Init.CLKPolarity  to SPI_POLARITY_LO...

what is the reason I2C peripheral does not work in master transmit mode in this program ?

i did not use standard peripheral library or cubemx to write this program . and i did it programming registers.as you know when data in TXDR register is sent the TXE flag in ISR register become one . i have checked ISR while no data is writen in TXDR...

STM32F7 Discovery - Audio input and output configuration

Hello, I am trying to receive input from audio in line and transmit the same signal through audio output on STM32F7 Discovery board. I am generating initialization code using CubeMx, but I need help on which parameters I have to set. I have checked t...
