Hello,I am using STM32H743 in master mode with I2C_4 in DMA Mode (configured using CubeMX, see attached capture).After sending command:HAL_I2C_Master_Transmit_DMA(&hi2c4, (uint16_t) ADT7411_ADDRESS, TxBuff, 2);I get an ACK from the slave but SCL line...
From what I understand, the UART gets a char/byte one by one. I am trying to test this by adding '-' between each character of the string I send to the UART. However, the outputted values are very inconsistent when more than 1 character is sent to th...
void RCC_Configuration(void){ RCC_DeInit(); //RCC_AdjustHSICalibrationValue(0x00); RCC_HSICmd(ENABLE); while(RCC_GetFlagStatus(RCC_FLAG_HSIRDY) == RESET) {;} //PLL out = (8M/2)*12 = 48 MHz RCC_PLLConfig(RCC_PLLSource_HSI_Div2,RCC_PLLMul_12)...
edit: the problem was due to a CAN-master switching baudrates on the fly.the wrong (slower) timing was detected by the CAN controller causing the interruption of the ongoing transmission.Hello Community !I am implementing CAN communication with an in...
I am using STM32L496 with ADC1/ADC2 in dual regular simultaneous mode with DMA and seeking to have ADC3 independent sinple single conversion. Code works either with ADC1/ADC2 or ADC3 but not with both. Can ADC3 run independent if ADC1/ADC2 are dual?
Hi,I´m reading the doc of my kits, stm32f767zi and stm32f429zi, but if anyone could help I´ll appreciate. I need start and stop a timer named htim3, as follow:if (HAL_OK!=HAL_TIM_Base_Start_IT(&htim3)) Error_Handler();But, if I execute the code twice...
Hello what does this function do?( LL_ADC_SetChannelPreSelection(ADCx, Channel);),I couldn't find a detailed explanation.
Hey,can someone help me to find the correct stm32_WPAN configurations to make an custom template witch can use the BlueST features an the ST BLE Sensor?BestEddy
I put my L4R5ZI chip into Stop2 mode but it doesn't seem to want to wake up from the user button, unfortunately. According to the datasheet, the wakeup sources include:Reset pin, all I/OsBOR, PVD, PVMRTC, IWDGCOMPx (x=1..2)I2C3(7)LPUART1(6)LPTIM1I h...
