Hi,I use a timer channel and a DMA stream to generate a PWM signal.At Transfer Complete interruption, I swap the channel to input capture mode to get an answer from external device, using the same DMA.At transfer (reception) complete, I swap again to...
Details: In the reference manual for stm32f303vet (rev 8) Figure 14, the PLL source is HSE by default if HSE is selected as source. In Page 140 bit Bits16:15, it says the default is HSE/2 and so on.This point is important since different stm32f303 va...

Hello, I ported wokring code from STM32F4 to STM32H7 (STM32H7A3NI). So far most is working as expected, however on SPI2 used as I2S the circular RX DMA1 Stream3 does not start. NTD remains on its initial value 0x800. The SPI2 has RXP and OVR set. The...
Hi there,I use backup SRAM and RTC in STM32F407. I have a diode between VDD and VBAT and 2.2u capacitors connected to VCAP_1 and VCAP_2. 3v CR1220 battery is connected to VBAT. Now the issue is that SRAM data are wiped when VDD power is off and batte...
We are migrating from STM32F103 to STM32L4. The code architecture is the same, as the product basically is the same. We just upgrade the micro. We have an SPI that is configured in slave mode, and a device that supplies clock to the SPI. DMA is u...
NUCLEO-F446RE board has 2 MCU. One is on the upper side(STM32F103CBT6) and the other one is on the downside (STM32F446RET6U). When we burn the firmware code, the code comes from DP/DM and goes to the upper one(STM32F103CBT6). Afterward, the upper one...
I am using STM32F411VE for testing I2C driver, in which i have defined 9 test cases using HAL_Mem_read, HAL_Mem_write, HAL_Master_transmit and HAL_Master_Receive(inblocking and non blcking mode(IT, DMA)). I have defined each test cases as a function...
