I am trying to use the STM32L452RE Nucleo to research an interface to an eMMC device. I have generated a project for this using STM32CubeMX. The eMMC device I am using has its interface voltage connected to 3V3, however, when I look at the CLK output...
Hi,I am working with STM32H743ZII was configuring GPIO output pins and I have to define "speed" which I assume is related to opamp slew rate. But I have a problem with the units, I can choose between "Very high", "High", "Medium", "Low". After readin...
Is it possible to use half-duplex mode and synchronous mode in the USART at the same time?I am trying to use USART with half-duplex mode and synchronous mode.When I refer to RM, it says "the synchronous mode is selected by writing the CLKEN bit in th...
Hello everyone, i have a custom made board using a STM32L476RCT6, i am able to normally upload the bin files with the programmer etc, it's working properly, except for one thing, i can't use the HAL_drivers as the same way i use them with the Nucleo....
I have diferent STM32F103-NUCLEOs conected via buscan, all powered by external suply 12V (VIN pin). When I supply 12V, all NUCLEOs start working but are not able to communicate via buscan. Then I pulse black button (reset button) of NUCLEOs and it wo...
When debugging, I saved the data in flash memory successfully and at soon the HardFault_Handler happened ,way? I used the same function in examples and the same Flash memory address. https://github.com/STMicroelectronics/STM32CubeL5/tree/a7a8ea66c42c...
Timer configurations are as follows: // Control registers(input PWM on channel 1 and 2[pin 12 & 13]) TIM4->CCMR1 |= TIM_CCMR1_CC1S_0 ; // Active input for tim_ccr1 TIM4->CCMR1 |= TIM_CCMR1_CC2S_1; // Active input for tim_ccr2 TIM4->CCER |= TIM...
Hi, I was following the STM32H7B3I-DK user manual and stumbled across this...Thanks,Heather
Error in STM32G4xx Reference Manual, RM0440 Rev 5, Page 702:"Bits 31:30 SMPPLUS" - This is only one bit, Bit 31.
I used SPI_DMA to transfer data by function HAL_SPI_TransmitReceive_DMA()。It is OK。I find it used interrupt. and it can be not changed to uninterrupted mode.Now I hope not use interrupt, how do I?
