Is ADC1&2 in Multimode with Timer Trigger and ADC3 standalone Software-Triggered possible?

Hi,I'm using STM32F767 and it's ADC. This STM has 3 ADC.I configured the ADC1 & ADC2 in multimode which is triggered by a timer. I also use DMA for data transfer. ADC1 and ADC2 both convert 2 channels (I measure voltage and current of two channels si...

Reading a speed sensor on L432KC Nucleo

I'm using a reed switch (a pulse per revolution) to measure the speed of a wheel. The sensor output is connected to PA12 which is TIM1_ETR pin. I connected it there by mistake in my final PCB. I would have to tweak the PCB if I want to change tim...

CubeMX 4.26 - new problems with STM32L4 USB device

Posted on June 11, 2018 at 16:58I tried to re-create my 4 well-tested USB device demos with 4.26. While HID mouse and MSC work flawlessly, two others do not work:CDC - COM port shows in device manager but cannot be opened in terminal; same basic cod...

USART1 behaved abnormal

hello allI established a virtual com port using a 4G modem, connected it with my F413ZH USART1.I used a DMA channel for RX. set HAL_UART_Receive_DMA(&huart1, (uint8_t *)&RxS0, 1);I could get datas from it at first. DMA2_Stream0_IRQHandler() will be c...

STM32F7 ADC Sampling Calculation

Hello, I'm using ADC with DMA of STM32F7 MCU. I want to calculate the ADC Sampling Rate. Is there a formula that I can use ? With 12Bit resolution, Is it possible to reach 2.4MSPS ? I'm using CubeMX for code generation.

STM32H753 208 pins, can read from SRAM but can not write to SRAM. The SRAM is Panasonic IC

 aTxBuffer[0]=0x11; HAL_SRAM_Write_32b(&hsram1, (uint32_t *)ADDR_MNM1221+0x0, (uint32_t *)aTxBuffer,1); It is a write code to SRAM but fail. The Panasonic IC MNM1221. The attachment is the datasheet.This reading code is successful. HAL_SRAM_Read_32b...
