Hi,I'd like to use USART for multiprocessor communication. For this I have to configure the TX pin to an open drain mode. But this option is not available: MCU: STM32F446ZEH6STM32CubeMX: 5.1.0Best regards,Eugene
i have light detection sensor circuit , it will give 1v output and 10 microsecond time period signal.this sensor gives voltage and time period varying depends on light intensity.i wan to measure the amplitude and time period of the output signal usi...
Hello,There seems to be some limitation about PSRAM controller and MDMA:Although that are several channels that can be used with MDMA, there is only a single interrupt for MDMA.If I understand correctly, it means that mdma can't be used with several ...
Posted on September 25, 2017 at 15:23Hey guys,for speed optimization I want to use ethernet interrupt when a new packet recieves. For this, first I changed heth.Init.RxMode to ETH_RXINTERRUPT_MODE and after that I added the interrupt handler with:vo...
STM32F302RBT...I want to use OpAmp1 in PGA Connected mode feeding ADC1 IN3. According to CubeMX the OpAmp pins VINP, OPAMP_VOUT and VINM are all 'Used' even though VOUT is internally connected to the ADC and VINM is not being used.If in the cube I ch...
Dear All,I have some problem with the STOP mode 2, doesn't work! In my program I use the following periphals:I2CSAILPUARTUART2My microcalculator is the STM32L4R5ZIT, and I use the nucleo EVAL board.To go in the STOP mode 2 I use the following command...
Hello,I see that MDMA is limited to 128 bytes (BufferTransferLength).Yet, when using DMA (with HAL_SRAM_Read_DMA for example) we can use larger size (up to 65536).Yet, I don't see in code that DMA is triggered more than once.Is it that these multiple...
Hello, i am very new to microchip stuff. I want to connect 13 laser sensors to STM32, any advice on how should i do it? I've been reading and asking around, and i read about expansion boards and serial expansion boards. Can anyone give me an advice a...
Is the calculation procedure in AN2867 "Oscillator design guide for STM8AF/AL/S and STM32 microcontrollers" correct? On page 12, Cl is given byCL = (CL1 x CL2)/(CL1 + CL2) + Cowhere CL1 and CL2 are loading capacitors and Co is the crystal shunt c...
hii have a problem when i generate a code by cubemx v5 ,i have a problem for my stm32h7 board.mcu wait at this line and can't init voltage regulator well, and wait on this infinity loop./** * @brief System Clock Configuration * @retval None */ ...
