I am not too familiar with embedded systems and just started learning about them. I have some parameters that lives in their own flash sector (16KB). They are stored as one long string ("PARAM1=X\r\nPARAM2=Y\r\n...." and so on). One of the parameters...
Hi everyone, I'm trying to use Input Capture with 1 Timer by using both edges option as external. I'm new at this microcontroller and I could not understand how to make it correctly with HAL library. Can anyone help me how to do?
Hi,I am using STM32H7's Timer 2 peripheral to generate a clock frequency ranging from 10Hz to 1MHz. To reconfigure the PWM to attain certain frequency, the PSC, ARR and CCR1 registers are modified.The sequence for modification is as follows: PWM_Star...
I'm having trouble understanding how the transfer complete interrupt is working.I have setup SPI using DMA to speed up data transfer to an LCD-display.The SPI clock is 18MHz, the System clock is 72MHz.From the book Mastering STM32 my understanding is...
My code works fine when STM32F303 ADC run at 8 bit, 3.6 MSPSWhen I trying to run ADC at maximum speed - 8bit 7.2 MSPS, DMA fails to get data. The bit OVR in ADC1_ISR is set and conversation stopped.If I read the ADC1_2_CDR register through the debugg...
I have configured PA2 as USART1 TX in STM32CubeMX, the code it generates looks correct:void MX_USART1_UART_Init(void) { /* USER CODE BEGIN USART1_Init 0 */ /* USER CODE END USART1_Init 0 */ LL_USART_InitTypeDef USART_InitStruct = {0}; ...
Hello all,I'm trying to communicate with SRAM device on my board.I'm using STM32H747XIH6 MCU.I tried to capture the Write enable, chip select and output enable pins on the board but I saw an unusual response of the output enable.My configuration for ...
I want to use the STM32F769I-EVAL Board to monitor a CAN netork. I configured the CAN module as it has been shown in the CAN_Loopback and in the CAN_Networking example.The Loopback Example does run on my eval-board. I take that as confirmation, that ...
Hey there,I am trying to replace an STM32F767 with an H723ZGT Nucleo Board. The projects uses a lot of heap - in the predefined memory configuration there is not enough place in the RAM_D1 sector. What do I need to do for changing the available RAM s...
I have not been able to get CAN2_RX0_IRQ or CAN3_RX0_IRQ to fire. CAN1_RX0_IRQ works as expected. It appears that rather than the CAN IRQs firing, the WWDG interrupt is going off for CAN2_RX0 and the DMA1_Stream0 is going off for CAN3_RX0. Neither th...
