how does HAL_ADC_Start_DMA() behave if the DMA is set to half_word

2024-04-07
HAL_ADC_Start_DMA() takes a pointer to a uint32_t buffer, but the cubeMX can configure the DMA for word, half_word or byte.So therefore you can only configure the DMA for word transfers?I was setting the cubeMX to half_word or uint16_t and using 12bi...

STM32CubeMX sets Timer 2 CC1E bit in the CCER register even when I select "Channel 1 Output Compare No Output"For Output Compare No Output Channel 1 I select "Frozen (Used for timing base)".I discovered this when trying to use the TIM2_ETR pin as a s...

FMC behaviour if read before a previous write cycle has completed

2023-05-02
I connecting an FPGA slave to an STM32F7 FMC 'sram' bus. For this particular project, I need to access the bus both inside and outside of an interrupt. Because there is a write FIFO, can I assume that writes are atomic and don't require mutual exclus...
