I'm modifying code for a Atmega AVR to a STM32L03 and encounter ISR(USART1_START_vect). It is a function that is called when the UART receives a start frame. I'm a newbie to this STM32-processor but I have googled and checked in inc-files but I can...
Hello,I'm using a NUCLEO-G431KB to create the PWM signals.I need to have 3 PWM signals plus their complementary outputs with same pulsewidth and a phaseshift of 120° between them, see picture below.In the video Hands-On with STM32 Timers: Internal Tr...
hi, im working on ADC, but ADC is not working, it is getting into infinite loop in this stage while ((hadc->Instance->ISR & tmp_flag_end) == 0UL)and my code follows like this HAL_GPIO_WritePin(GPIOH, GPIO_PIN_7, GPIO_PIN_SET); // get ADC value ...
Hello friends!I have been messing around with the onboard opamp and here is the problem. When I configure it as the follower, things are okay, but as soon as I configure it as an AMP with PGA on and set any gain, I see quite dramatic DC shift on the ...
htim3.Init.Prescaler = 20 - 1; htim3.Init.CounterMode = TIM_COUNTERMODE_UP; htim3.Init.Period = 200 - 1; sConfigOC.OCMode = TIM_OCMODE_TOGGLE; sConfigOC.Pulse = 0;I am using a NUCLEO-L476 and have a 20MHz clock source. I am using no interrupt...
Chipmodel : STM32L431RBTxI use M24C04-WDW6TP EEPROM on I2C line and read it using HAL_I2C_Mem_Read() function.In normal condition, HAL_I2C_Mem_Read() works well. But After download binary to MCU using ST-Link, 1 case in 1000 times try, HAL_I2C_Mem_R...
Hello guys,This is a silly question, but still cannot get it right.I want to read different values coming from sensors connected to different ports.I know using 16 available channels for external input is very intuitive when all the inputs come from ...
What is the best way to create 480 1us pulses (to clock an A/D) every x seconds?Can this be done with one timer?
I'm working with the STM32h747-DISCO with Keil Development tools and an ST-LINK debugger, and I'm trying to use the Debug (printf) Viewer. I can get it to work properly on the M7 core, but am getting "No Synchronization" when I try to use the M4 co...
Hello all...I have 6 channels of A/D that I want to sample continuously for 480 samples total. I want these samples to be triggered on the rising edge of event out of Timer3 every 5 seconds...I have tested Timer3 using toggle and GPIO and it looks a...
