I need to measure the On and Off times of a possibly asymmetric signal. Measuring frequency is a classic TIM Input Capture function, and in this case one is tempted to set the capture for both edges. Within the ISR, however, is there a HAL approved...
Build ErrorError[Li006]: duplicate definitions for "HAL_SPI_TxCpltCallback";void HAL_SPI_TxCpltCallback(SPI_HandleTypeDef *hspi) { HAL_GPIO_WritePin(SPIx_NSS_Port, SPIx_NSS_Pin, GPIO_PIN_SET); }I use the same in both files ?any way ? please help
we started evaluating the controller architecture with respect to our application requirement. We are referring application note AN5557, Reference manual for the suggested MCU.While referring the documents, we understand that there are 3 Domain in th...
I want to test TS with one normal touchkey. I use the STM32L152RETx on the Nucleo-L152RE.I want to use hardware acquisition mode to keep the CPU in sleep mode until a touch is registered. As I understand the UM1913 the L1 series is using TIM9 and TIM...
Hi, Team,It can running the polling mode function HAL_SD_ReadBlocks successfully in my hardware/software platform. When switching to IDMA mode with HAL_SD_WriteBlocks_DMA, the 1st block data could being read out correctly but without the SDMMC1_IRQ...
I am simulating stm32f103c6 in proteus,I want to do timer2 interrupt ,I set pre = 7200-1,psc = 10000-1,so 1s to timer2 update interrupt.But time is not correct,it does not work.I look up information,it is said I need to change stm32 clk to 8MHz,not...
I am trying to use dma with timer 2 in order to change the dutty cycle of a pwm output in each cycle. However, I get a dma transfer error.
Hello, I need to find a free CANopen stack. I have found CAN festival, but I can not figure out how to configure it for STM32. I would appreciate any help. Also, please advise on any other free CANopen stack for STM32.Thank you and best regards,Vouri...
