Resolved! In Clock Source BYPASS mode, can we use the OSC_OUT as GPIO?
Hello Community,We are using MEMS OScillator for the clock source for STM32G474 MCU. And are unsure if we can use the OSC_OUT pin as a GPIO pin when using the MCU in Clock Source BYPASS mode.The datasheet mentions we can, I, however, would like to co...
How to configure AHB and APB for STOP Mode on STM32L4?
Hi,I was following @Laurids_PETERSEN post on his low power ThreadX example (Part 2 ThreadX Low power Project ). I noticed his sample code, Snippet 11 on Enter Low Power mode configured the APB ENR, AHB ENR in RUN mode and then disabled all the periph...
Multi ADC READ
I am trying to read Analog voltage from two different channel one is mains supply and another is battery voltage.But I am getting both values same in live expression window.Does my config wong.Pls helpvoid ADC_Mains(void) { ADC_ChannelConfTypeDef s...
stm32 pwm intrupt / hal handler
hello i m using tim1 to generate pwm and using center alligned mode 1 , timer go to 0 to 1800 then 1800 to zero for one pwm cycle and generate 2 intrrupts HAL_TIM_Base_Start_IT(&htim1); //intrrupt i am using//handler is void HAL_TIM_PeriodElapsedCall...
Resolved! GPIO, ADC and DAC not simultaneous
I am using stm32 g071 and what I have done in the code is to toggle pin and send the value through adc and finally output through dac. Theoretically, the GPIO output and DAC output should be simultaneous but due to processing time and all, there will...
Resolved! FDCAN problems on STM32G4
I am developing a new project for the STM32G474 processor using the STM32G474E-EVAL1 board but am having a problem with FDCAN. I have two issues:1. I configure FDCAN and use the function HAL_FDCAN_AddMessageToTxFifoQ but the queue quickly fills up a...
Disturbance in MIPI DSI Output Image
Hi EveryOneBy Using DSI in Video Mode, It makes this disturbance in out image, What's the Main Source of this Problem:1. PCB Design (It's Two Layer Board, I tried My best to route it as short as possible)2. Noise in Ext RAM Data (Using EXT RAM as Fra...
Resolved! Timer triggered DMA to GPIO for soft PWM
I'm trying to to generate a PWM signal on a GPIO without PWM capability on a STM32F47. To achieve this, I want to have a timer triggered DMA transfer to the GPIO BSRR register.Looking at the bus matrix, it seems that I need to use the DMA2 controller...
Resolved! RTC subseconds count down
I am using the RTC of the STM32L4 Discovery board and have noticed that the sub-seconds are counting down. Is there anyone with an idea on how to resolve this issue?
