Waking from Standby with any GPIO with STM32L4?
I thought of using an STM32 to build a device which responds to infrequent pushbutton presses, but should also conserve battery. My initial instinct was to use an STM32L4 in Standby or Shutdown mode, setting the GPIO as external interrupts which woul...
How to interfacing RFID with UART communication in stm32f429iit6
Hello, I am using STM32F429IIT6 board . My board is customized and i have Only 6 pins that are PI1(GPIO_input), PH13(GPIO_Output),PA9(UART_Tx),PA10(UART_Rx),VCC,GND. I want to check data through putty. But i am not able to understand how can i make ...
STM32L162 LQFP64 device marking
Hi! We have received STM32L162 MCU in LQFP64 package with device marking that doesn't follow the datasheet. In the datasheet for this part product identification lines should be likeSTM32L162RDT6but on the part we had received it isSTM32L162RDT6So th...
Resolved! I want to sample one (of six) ADC channel for 2 ms in blocking mode. How hard can it be?
I using STM32CubeIDE and STM32L03.I don't understand how to make a simple sample of a ADC channel (in blocking mode). I had config the Cube to generate a ADC_Init() that contains my 6 Analog In channels. I want to have a function that goes like this...
Resolved! when exactly void HAL_I2C_ErrorCallback(I2C_HandleTypeDef *hi2c) will be triggered and i have enabled the error interrupt in IOC setting but i could not understand occasion of this happening .
HAL_I2C_IsDeviceReady is good option to check sensor presence but while i2c sensor working incase of error occurrence will error interrupt will be triggered ?
Is anyone using Rust here , any toughts?
Does it deliver what it promises? (you could helloworld a web page and a microcontroller with no big code difference)Is it worth the hussle of learning it?Is there any real example of a situation where Rust saved the day?
I have UART1 and UART2 configured. I am looking to bridge the two together. UART2 (115200) & UART1 (9600). UART2 (PC VIA USB) and UART1 [DMA, Circular (word)] (Connected to external device UART interface).
Code snippet```while (1) { HAL_UART_Receive_DMA (&huart1, UART1_rxBuffer, 100); HAL_UART_Transmit (&huart2,UART1_rxBuffer,sizeof(UART1_rxBuffer),100)}void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart){ uint8_t UART1_rxBuffer[100]...
Resolved! Software migration from STM32F207IGH (Cortex-M3) to STM32F427IIH6 (Cortex-M4)
STM32F207IGH used in the existing product. We see that we need more Flash & SRAM to include more software features. STM32F427II is having double the size of both Flash & SRAM. What is the process to migrate software to STM32F427II? Micrium RTOS used ...
