Hi i am receive data using UART 4 and transfer same data back like loopback but data is mismatch. same process in stm32f207 is working, #include "main.h" UART_HandleTypeDef huart4; void SystemClock_Config(void); static void MX_GPIO_Init(vo...
Dear community, on the ADC3 IN18 (internal temperature), I have an unconsistancy between the output of the ADC (reflecting the value of the temperature and the reference value TS_CAL1 and TS_CAL2 (0x3114 and 0x40C0).the ADC is in 16 bits and I got a ...
We are planning to make a board using a STM32 MCU in a Modbus application. What we need is a Modbus-RTU. We found that STM32F030 can satisfy our needs and cheap enough but it does not support Modbus. Could we use STM32F030 in this case by special sof...
When I configure ADC1 to read voltage input from PA0 and PA1 using DMA, then the behavior is as below in each condition1) PA0 = 0 (GND) ; PA1 = variable pot (0-5V)then PA1 provides values as per input from pot but max value displayed in 3022 instead ...
Hello,I would like to use an ADC using DMA in 12-bit mode. Unfortuntaly, the adc value is only 8-bit which doesn't match with my configuration. I've already tried to solve the problem by trying the solution proposed here: https://community.st.com/t5/...
Hello,I have a STM32H7A3 dev board (NUCLEO-H7A3ZI-Q) and have connected it to a OV7670 camera using DCMI interface. I used an example from Cube library (for DCMI) that grabs single image from camera and stores it in the internal RAM of a microcontrol...
Controller: STM32L011G4ULibraries: CMSISCompiler: arm-none-eabi-gcc version 13.2.1In order to change Capture Compare Register of TIM2 automatically every time when TIM2 updates, I want to use DMA to get the current CCR values from a const array. cons...
Hi CommunityI am using this STM32H747 and cannot find the project in the "en.stm32cubeh7-v1-11-2". Similar to the use of STM32H743 , I can find the corresponding project in the "en.stm32cubeh7-v1-11-2" . Can you provide the projectscorresponding t...
I tried enabling Continuous Conversion Mode and only keeping the first HAL_ADC_Start(), but I no longer receive ADC data afterward. Is this normal, or did I miss something?
I am trying to interface CAN communication in loopback mode in STM32F469I DISCO but it is not working.
