This is my test program：uint8_t dev_test=0x00;while(1){HAL_GPIO_WritePin(DW_NSS_GPIO_Port, DW_NSS_Pin, GPIO_PIN_RESET);HAL_SPI_Transmit(&hspi1,&dev_test,1,10);HAL_SPI_Receive(&hspi1,test_R,4,10);HAL_GPIO_WritePin(DW_NSS_GPIO_Port, DW_NSS_Pin, GPIO_PI...
Hello Experts I am beginner in STM32 , I have a old Discovery STM32 board , I want do some project, Now I require some already availabe libraires ,I dont know where can i get it ?Help me to findout ?
The STM32F070RBT has Hardware Flow Control for RS485, with DEAT, DEDT and DEM bits in USART_CR1 and USART_CR3 registers.How do we identify which series of ICs have these features easily? Is it a particular series or type? The STM32F4 IC we are curren...
That's how it looks: Started the TIM4 interrupt mode:/* USER CODE BEGIN 2 */ HAL_TIM_Base_Start_IT(&htim4); /* USER CODE END 2 */The counter values should be incremented in the middle and in the end of the period, however it doesn't happen. There...
Hi,I am using the NUCLEO-32 STM32L011 kit and I want to put the MCU in stop mode to measure Idd. Everything seems to be going well but when I measure the current, this is 2.5µA versus 0.5µA announced in the datasheet when the stop mode is activated w...
Hi all i am working in interrupt driven uart uart2 which is connected to the usb port in nucleo -g431rb The interrupt handler is not been called I have shared my code any thoughts kindly share.void USART2_IRQHandler(void) { /* USER CODE BEGIN USAR...
Hello.I am using a supercap as rtc backup battery on my STM32G4 processor. There is a bit of high consumption as I drive the RTC crystal high. But the highest consumed current is 0.8uA.The product I chose is SCMS22D255PRBB0. However, it discharges qu...
Can I get a demonstration or application note or some how LED blinking program (I had build an Hex already for STM34F030R8T6 LQFP), Any link or thought process will be a great help for me to move away from this ? Thanking you in advance!My Simulation...
Hello folks,I can't figure out the meaning of table 48 p.64 of STM32G070CB datasheet (see attached picture). In particular the FT_c pins. Page 63 it is written that all I/O can source up to +-6mA and +-15mA with relaxed VOL and VOH.Back to table 48, ...
