Hello Everyone,I am using the stm32h7 to sample 4 channels from adc1 using the DMA.I am using circular mode with half word size. I start the dma and let it fill up a memory buffer:volatile uint16_t adcInsDMA[4*ADCBLOCKSIZE] = {0}; HAL_StatusTypeDe...
Hi all,Just started with bare metal programming of stm32f411re.Uploaded the following code to blink the onboard led of the nucleo board.Code:#include "stm32f4xx.h" // Device headervoid delayMs(int delay);int main (void){RCC->AHB1ENR |= 1;GPIO...
When using a 16 bit data bus, the STM32CubeMX generates outputs for FMC_NBL1 and FMC_NBL0 that connect to the SDRAM DQMH and DQML pins. If the STM32CubeMX is configured for an 8 bit data bus, there is no DQM pin generated, although the 8 bit SDRAM h...
Hello,I want to ask if it is possible to drive TFT with FMC (Flexible Memory Controller), our TFT has only MCU interfaceI think EMwin has no option for MCU interface at STemWin_CM7_wc16 library.We used same TFT with STM32F207 by using FSMC .If its n...
Which Xferoption should be selected and should we use both functions ieHAL_StatusTypeDef HAL_SMBUS_Master_Transmit_IT(SMBUS_HandleTypeDef *hsmbus, uint16_t DevAddress, uint8_t *pData, uint16_t Size, uint32_t XferOptions)andHAL_StatusTypeDef HAL_SMBUS...
i replaced board mcu from stm32f103c8t6 to stm32l412cbt6.now i cant connect board with swd port.is stm32l412 not support swd port by default?or do i need to change some schemetic for stm32l412?
Hi All,I am trying to generate required no of pulses using PWM. This is to implement to control stepper motor with position control. I use HAL_TIM_PWM_Start_IT to start pulsing and count the no of pulses in HAL_TIM_PWM_PulseFinishedCallback. I notice...
Hey folks!Got some questions around synced timers on STM32F401, where the aim is to have two timers start together, where one timer has a period an integer multiple of the other. I've got what I need working but how it works, doesn't add up.Here's th...
Hello everyone,I'm just starting to learn assembly for the ARM architecture. I'm also in general a beginner with the assembly language I have just some minor experience with the x86 assembly but that's about it.I'm following a course on Udemy and I h...
Hi,I have a custom board with an STM32G474RE. I use 3 CANs with 3 independent CAN tranciever on the board. I tried sendind CAN message from CAN1 to CAN3 but the message is not received. At least the callback funnction is not called. I used an oscillo...
