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...
We have a project which reads CAN data on both FDCAN ports. Bitrate 500 kBit is working perfectly, but with 1 MBit no data can be read. PIN-Speed = HIGH (also tried MEDIUM and VERY_HIGH, but no change)CAN-Clock = 80 MHzWe already tried CAN Bittiming ...
I am trying to trigger every millisecond, or 1000 microseconds, but my counters in the interrupt are seeing 167 interrupts per second as opposed to the expected 1000 interrupts per second.I am reading 6 channels with a sample rate of 92.5 clocks per ...
