Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
hi I have an encoder that has channel A channel B 5 volt output only and I wonder if it is possible to read gpio interrupt with a cortex m4 since it works at 3.3 volts? Do you need a logic level converter, some resistor or read it anyway?
I have a STM32F303 acting as a serial port to an industrial control system, but I need a reliable way to set a byte for out-of-band data (I need to set "termination resistor On/Off, Drive Strength, etc -- I'm using the "comm port" for the serial data...
The SPI Bootloader function of the STM32F730R8T6 is being developed, using the pin of SPI1, but there is no normal response, and the response is 0xff or it takes a long time to return to 0x79.
I'm having problems getting an ADC value from the STM32F777IIK chip we have embedded in one of our boards.I have used a digital GPIO application and have confirmed that the ADC pin (PC0) is connected from the chip to the headers that is good.I have u...
I'm new to STM32 processors. I'm learning on a Nucleo F103rb board. I was able to receive a single character through UART in polling mode, but unfortunately I have difficulties in receiving more than 1 character. It would be used for the device to wa...
Howdy,As the title suggests, I seem to be having some issues with FreeRTOS if I try to use a timer as the timebase source. The processor that I am using is STM32F745VET, but the MWE that I will try to describe should work on any system.The SMT32CubeM...
Hi, according to the Reference Manual and the Datasheet of the STM32L152 the I2C cores are supposed to support SMBus. However, there are no HAL drivers for SMBus for this MCU. If I configure the I2C cores as SMBus in CubeMX, CubeMX will generate Init...
I have the following couple of questionsQUESTION :1) what is the difference between USB drivers in the cubemx standard hal library middleware and CMSIS USB Middleware based on the following 2 cases?CASE:1) In STM32CUBEMX, When I use STM32 standard H...
I am using HAL_I2C_Master_Transmit and HAL_I2C_Master_Receive commands to read device ID of various sensors. I wrote a simple code to do that. It works for some sensors (e.g. MCP9800, HDC1080). But it doesn't work for some other sensors (e.g MLX9016...
hi I am handling two different interrupts:- tim3 interrupt- gpio external interruptnow I want gpio external interrupt to have a higher priority than tim3 and that can also interrupt tim3 ....How can set i? HAL_NVIC_SetPriority (EXTI15_10_IRQn, 0, 0);...
