STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
Hello everyone,could someone please help with the following, I am trying to use ADC with interrupts. Doing the same thing with STM32F103C8T6 it works without issues, but using nucleo board it doesn't.Could someone please have a glance on the code ? (...
Hello, we're using the microcontroller STM32F302C8 and we have a problem with the PLL.The problem is when we enables the PLL the microcontroller is reset. We have made several tests using HSI and HSE, but always the same result, a reset after to enab...
