How Can I measure the input frequency by Timer Input Capture?

2022-02-22
Hi I measure the frequency from sensor using the Timer Input Capture mode. I set the timer can read minimum 1Hz.72M / 7200/65535 = 0.15HzThis is my code. void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) { HAL_GPIO_WritePin(LED_PORT, IN_LED_...

I can't find the PULL UP menu in STM32CubeMx. (to use i2c1)

Hi AllI have simple question about STM32CubMX.I use the STM32F103RBT and test the i2c with eeprom.When I set the pin for i2c, I should change the GPIO Pull-up/Pull-down in STM32FCubMx.But This menu is not in STM32FCubMX.I don't connect external pull ...

Hi all,I test the timer input capture mode. The input range is 1Hz ~ 100Hz.I set the parameter as below. (Using CUBEMX)Timer Clock : 60MhzPSC : 6000ARR: 10000void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) { HAL_GPIO_WritePin(LED_PORT, IN_...

stm3240g-eval eeprom(M24C64) issue.

2020-09-07
HelloI test external eeprom (M24C64) on the STM3240G-EVAL. But it doesn't work well. HAL_I2C_Mem_WriteBytes() and HAL_I2C_Mem_ReadBytes() return the HAL_OK.But when I check the data[] buffer, the value is all "255".This mean that memory is empty? The...

I have a problem which make a lwip project with Cubmx. (It doesn't work Ping )

2020-09-01
Hi allI use the STM3240G-EVAL. CubeMx version is 6.0.1 and using TureStudio for ST32.I try to test the lwip for a few days. But it was not working.I referenced the "Lwip_Echo_Server example" project which before is the HAL library.It works well.(ping...
