Hi,in ds for STM32H747xI/G , DS12930 Rev 2 , for Temp.sensor CAL2 : 130° (Parameter) is written here: BUT max. temp for chip is 125° :So i assume, this is misspelled , because in all other : (H743, H750, H7A3 ..) 110° + 30° are given.NOT 130° .
I am new to STM32, I am using Nucleo STM32F446RE board and programming in C in the program Keil, and I am facing an issue that I can't resolve, trying to download my program, whenever I tryy to download it it says " no target connected" then another...
Hi, i am using STM32H753z i try to switching FDCAN GPIO is PD0, PD1 to UART tx and rx (same pins)now i changed FDCAN to UART tx side is fine but in Rx side i face issue ( no data is receiving to receive buffer). #define CAN_AFR 0x99 #define ...
Hello, We are using STM32L412RBT6 MCU for our inverter and battery charger application. We are facing as issue like ADC stops reading and all the ADC results are giving same and random results. We are reading the result through DMA. We couldn't find ...
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...
