In my application i desire to use the STOP2 Mode in a certain condition to save power. Currently i want to implement a wakeup through a "HIGH" on Wakeup Pin 2 of the MCU. Later i want to implement also a periodic wakeup per RTC. But for now, i want o...
Dear Sir,I used the STM32L052R8 CPU with 32MHz to try to generate a "1KHz sawtooth waveform with amplitude changeable from 1.5V to 3.0V" with 『HAL_DACEx_TriangleWaveGenerate(&hdac, DAC_CHANNEL_1, DAC_TRIANGLEAMPLITUDE_4095);�? function. But it fail. ...
Hello,I've configured the stm32h743 to write on a paticular adress without incrementing it and was also successful in it.The problem is no matter how many times i call HAL_SRAM_Read_DMA(...) it will not start a new transfer. In the trainings Manual t...
Hello guys,I've been trying to enter the Standby Mode using the Exemples from st and i got it work. But in Standby i'm still around 6mA. This is much more than the expected 5 µA! Maybe someone knows what may cause this Behaviour?thank you for your he...
My timer config: RCC_APB1ENR = RCC_APB1ENR_TIM3EN; TIM3_CR1 = (uint32_t)(TIM_CR1_CKD_CK_INT | TIM_CR1_CMS_CENTER_3); TIM3_CR1 &= ~TIM_CR1_UDIS; TIM3_CR2 &= ~TIM_CR2_CCDS; TIM3_ARR = (uint32_t)10000; TIM3_DIER = (uint32_t)(TIM_DIER_CC1DE | TIM_D...
Hello, all!I'm using STM32F100RBT.I have the following code:printf("hello\n"); while(1) { HAL_PWR_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_STOPENTRY_WFI); HAL_Delay(100); printf("***\n"); HAL_Delay(100); }The first print before the loop is...
We have an application already running properly on STM32F411 which runs at 100mhz.When running it on STM32F405 which runs at 168mhz, there are issues e.g., COM port connection to PC etc.Seems this is the difference between 100mhz and 168mhz. See http...
Hi everyone. As the title suggests this might come across as an odd request. Basically I have been given a fully completed board with the microcontroller already placed on it. I was asked to use it to generate PWM's from it and control a full bridge ...
Hey guys/gals, I have a UART TX and DMA issue, I can't call HAL_UART_Transmit_DMA sequentially in the same functions, the first call is successful but the UART gstate gets stuck in the TX_BUSY state so a second call fails to execute. Heres some detai...
Hi Team,I'm using NUCLEO -STM32H753 Evaluation kit. Instead of the ADC channels he provided, I'm going to take the 50KHz input from demodulator where as inputs are I and Q to Connect to the internal ADC of this STM32H753ZI MCU. For this configuration...
