Hello, I'm using the STM32746G Discovery Board to familiarize myself with the ST environment. Now I simply wanted to store a 32Bit value in the RAM, and had several problems with the Cube BSP drivers. I tested the functions with the following code: #...
Dear all,I have a board with only the STM32F765VIT6 and I program through the stlink with a power supply of 3.3V (.At start of program i tried HAL_PWR_EnterSTANDBYMode() to get 3.5uA with success if before i disable overdrive with HAL_PWREx_DisableOv...
Hello,I wonder if I use the internal pullup resistor on an STM32F4 on an open-drain output, if the MCU is reset with the line NVIC_SystemReset(), does the internal pullup resistor with open drain output will still be seen by another IC connected to t...
Sometimes I'm getting a I2C_EV interrupt called and none of the possible flags which can cause an interrupt are set. Only flags that are set are BUSY and TXE (ISR is 0x00008001), both of which shouldn't cause an interrupt.void I2C1_EV_IRQHandler(void...
I am going to convert my project from stm32F417IGT to stm32F769IGT. Is it ok if i just replace them ? Because i noted they have same footprint and pin configuration -
I am trying to store configuration data in flash on the STM32L151CB-A using the HAL libraries. I reserved the last page in flash for this. However, I see that already at the beginning of main the OPTVERR bit is set. (FLASH->SR: 0x80C) I never program...
hello everyone,i'm using a STM32F301 MCU on a newly custom designed PCB. i'm using a NUCLEO board to flash the MCU thanks to SWD connector (CN2 jumper off).The SWD pins are SWDIO, SWCLK, GND and VCC. The first flashing succeded and the programm in wh...
Posted on September 24, 2014 at 13:18Hi,I have a STMCube generated project wirh I2C memory 24LC512 with following problem. The line:Status = HAL_I2C_Mem_Read(&hi2c1, IIC_ADDRESS+1, 0, I2C_MEMADD_SIZE_8BIT, pNVRawData, NVRawDataLen, 1000);is correct ...
I see a lot tft on ebay and aliexpess which come with libraries and support for arduino and raspberry.I do not see anything for STM32. I am trying to get working 320 x 480. On arduino I had it working the next day, tons of sample programs and librar...
I am trying to initialize my external SRAM before the main loop runs. Using the STCubeMX it generated the code for me to have me FMC controller initialized after Hal_init() and Hal_GPIO_Init() in Main.c. However, I need the SRAM to be initialized bef...
