Hi everyone,I workin on a project that use STM32F746BG microcontrollers. I completed design and mass production process for PCB's. Now I working on software that use TouchGFX, LWIP, 7 inch Display and many other component for project. But I fulled 32...
HI all,I am developing a CAN FD application using STM32H750-DK. Packet reception to FIFO is working in External Loopback mode and packet transmission works as well. But once I change the mode to Normal, packet reception (FIFO interrupt) dosent fire I...
Hi everyone. I am using a stm32f429i-disc1 board to read data from the dht11 sensor, but it cannot read the humidity and temperature. I attach the code that I am using.The screen displays "Hello world!", "Humidity: 0.0" and "Temp: 0.0", and when I u...
Hi,on a STM32L451CE I try to make use of TIM2 timer. I want to start this timer on an external trigger event. From the device datasheet I know that the pin PA0 can be used with AF14 as a TIM2_ETR. However when I setup the timer it doesnt start counti...
I am doing i2c reads in my while(1) loop. I do have an external interrupt source. I wonder, if the external interrupt arrives while data is being sent on i2c bus, what will happen? The mcu will enter to interrupt service routine clearly, will i2c per...
I have chosen the STM32L07 as it has a LPUART that, from my reading, is ideal for my project where I have to communicate with an SDI12 sensor running 1200-baud 7-bits even parity. When I try and change the 209700bits/s default in the STMCubeMX to 120...
I'm using the template code for the STM32F7508-DISCO from the STM32CubeF7 repository with the only change being that I add a LED toggle and a busyloop to an infinite loop in `main`. The startup code and everything else is per the template.If I flash ...
HiAs the title mentioned, I can't find relevant information in the datasheet.I get some problem when using UART. I have two chips, the master chip transmits packages to RS485 Bus line, and the slave chip receives it then transmits the respond(UART1),...
Here is the RTC initialization code:static void MX_RTC_Init(void){ /* USER CODE BEGIN RTC_Init 0 */ /* USER CODE END RTC_Init 0 */ RTC_TimeTypeDef sTime = {0}; RTC_DateTypeDef sDate = {0}; /* USER CODE BEGIN RTC_Init 1 */ /* USER CODE END RTC_Init 1 ...
