Resolved! calculating temperature for STM32L451 - tried both methods, but don't get correct readings
According to the data sheet, the calibrated values for specific chip (at 30°C and 130°C) are at the following addresses:#define TEMP30_CAL_ADDR (*((uint16_t*)0x1FFF75A8)) #define TEMP130_CAL_ADDR (*((uint16_t*)0x1FFF75CA))Therefore the calculation s...
Resolved! Volatile qualifier does not matter in my interrupt routine
I am new to embedded C, and I recently watched some videos about volatile qualifier. They all mention about the same things. The scenarios for the use of a volatile qualifier :1. when reading or writing a variable in ISR (interrupt service routine)2....
STM32F429 Flash write/read
I'm trying to write and read some data into flash. But not work. Anybody help me?I'm using Cubeide and STM32F429 board.char test_data[]="TEST";char test_data2[5];uint32_t PAGEError = 0; FLASH_EraseInitTypeDef EraseInitStruct; EraseInitStruct.TypeEras...
FDCAN - multiple frames sent from single send request
Hello,I'm beginning to bring up a PCB which is based on the STM32G484QET. Initially, I'm getting the FDCAN set up (although I'll be using it as a CAN 2.0 node). I am using FDCAN1.I'm at the stage that I can transmit CAN messages which are picked up c...
Counting up from GPIO READ
Hi,all:I wrote a code for counting up when GPIO ReadPin change high level to low, here is the code:while(1){ HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1, GPIO_PIN_SET); if(HAL_GPIO_ReadPin(GPIOE,GPIO_PIN_10)==1) { HAL_Delay(1); if(HAL_GPIO_ReadPin(GPIOE,GP...
UG96 cellular module interfacing with STM32H743ZI
Any one have an any idea Of firmware development of UG96 GPRS module with STM32H743ZI controller
Using ADC1 for very fast readings of IN1 and readings of other channels every 100ms
Hello,I have 7 ADC1 channels that must be read every 100ms. I can't use polling because there are many other tasks being done in the foreground. I can either set up in the interrupt a type of chain in which each time one value is read the next one wi...
ST, please improve learning materials.
Hello,I’d like to offer ST some advice in there educational materials. I’d be willing to work with ST to improve such things if asked.If I’m not mistaken, I think this video is out of date: https://www.youtube.com/watch?v=6RqUkFIeN6wI find it confusi...
