Hello,My timer PWM channel is connected directly to a mosfet driver. By using TIM_Cmd(TIM2, DISABLE);it puts the output at high level. I tried to use TIM_DeInit(TIM2); but it generates an additional pulse in the output ( I count the each PWM pulse in...
Hello,I use stm32f765BITx processor and SDMMC (SD 4 bits Wide bus ), sometimes code is stopping at SD_FindSCR function in stm32f7xx_hal_sd.c library. This event is happening random.Exactly, the place where code stopped at SD_FindSCR function,while(!_...
According to AN5354:Page 13 / Table 12: Number of ADC = 2, resolution = 12, LQFP100, maximum ADC frequency is 35MHz (providing 70MHz from PLL2P before /2 divider)Page 15 / Table 16: Direct 4.38 MSPS Fast 3.83 MSPSAnd according to formula from RM: Tco...
STM32L1xx HAL Driver version number V1.4.3Why does FLASH_WaitForLastOperation() not check the SIZERR flag? is this a bug? And the FLASH_SetErrorCode() does not clear the SIZERR . Is this a bug?
Hi,I am trying to setup the TIM1 of the STM32F410CBT microcontroller so that TIM1->CNT can measure Channel A and Channel B of a Quadrature Encoder Interface of a motor (the Encoder's datasheet is here, and it came attached with this motor here). I ha...
HiI am using CubeMX to setup a project to measure pulses using Timer 3 Input capture. However I am not hitting the Timer 3 interrupt.I have on my main code:int main(void) { uint8_t test; /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MC...
According to the data sheet, sec 3.13.3 says the VBAT voltage is measure by the ADC as VBAT/3, or one third Vbat.using : uint64_t volt = (uint64_t)(((uint64_t)3300U*adc_result)/(uint64_t)4095U);I get 2/3 VbatChanging to uint64_t volt = (uint64_t)(((...
I wrote a simple LED blink program using STM32F767zi board. It works properly when I use STLink debugger. but the problem is when I remove the STLink and connect the board directly to an external power source, the code does not execute until I manua...
Hello,I have an interrupt driven I2C which is working fine. I know that this is not very clean design but I need to execute few I2C transactions from a button interrupt handler (EXTI9_5_IRQn). I have set the priority of the EXTI9_5_IRQn 1 and the pri...
