Hi,I am using STM32G4 in my project. I need delays in my project multiple places. I am using hardware timer interrupt for delay. I am using TIM1 configured with 50 usec delay. HAL_TIM_Base_Start_IT(&htim1); HAL_TIM_PWM_Start_IT(&htim2, TIM_CHANNEL_2)...

Hi,I need microsec/millisec delay in my project but I don't want to effect the process flow.I am using STM32G4.I am using timer for microseconds delay below is the function.void delay_us (uint16_t us){__HAL_TIM_SET_COUNTER(&htim1,0); // set the cou...

Hi,In my project I need to bring up stm32g4 IC in custom board. Can anyone tell me the process to do that.1. Bootlooader flashing: Do we need to flash the bootloade in to IC?if Yes,Where can I get the bootloader for STM32G4 IC.What is the process to ...

Hi,I am sending/receiving data using UART between STM32G4 board and other board. While I am sending the data I am adding the CRC and transmitting it through UART to other board. While receiving how do I check the CRC correct or not.For Eg: From other...

Hi,I am working with STM32G491RE.I am giving pulse to GPIO pin from function generator. That pulse will be 2 msec on time and 8msec off time.I need to make flag high if the signal from function generator lost.Can anyone suggest me how to do this?void...

Hi @Gwenole BROCHARD ,Can I use one timer for different delay's. In my project I need many number of delays like 50usec,750 usec,3 sec,2sec,6sec and 100usec etc in different places. I want to use single hardware timer with interrupt for these delays....

Hi @STOne-32 ,>>>Do you have already your board ready ? And all hardware is well tested I received a custom board PCB from hardware team. It has STM32G491RET6 IC is assembled on it along with required hardware. For this basic example check is enough...

Hi @Tesla DeLorean,1.So it's using the default 32-bit polynomial?-------I think so, not sure.I am using STM32G4 series .As per CRC application note below tables says polynomial coefficient is programmable. Based on what basis do I need to select poly...

Hi @Tesla DeLorean, @TDK hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_ENABLE;Is above statement don't make polynomial enable? Do I need to give value separately?is below code correct way to do?CRC_HandleTypeDef hcrc;MX_CRC_Init();static void M...

Hi @TDK,is it correct?volatile uint32_t last_input_change=0;const uint32_t pulse_timeout = 10;void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){if(GPIO_Pin==Zerocross_detect_Pin){last_input_change =HAL_GetTick();}}void fault(){uint32_t last_input_change...
