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...
I am using STM32F429 nucleo 144 board for security application. I Need to read a unique ID while doing this process i am getting ST-link SN number of the device. So is SN of the microcontoller is a unique number ? or is it common number for all STM d...
您好： 我使用STM32F303RBT6的ADC2_IN3时，�?�现�?��?将PC4脚输出高电平时，ADC2_IN3采样的数�?�就会有异常。 譬如ADC2_IN3脚接GND，PC4输出高电平，ADC采样�?�回的值为0x70;而将PC4输出低电平�?�，ADC采样就正常为0了。 请问这是什么问题？谢谢�?
Hi everybody,I'm complete noob and may be a silly question. But is it possible to connect WS2812b to a blue pill? As far as I know WS2812b hav 5V management logic and STM32 here gives 3.3VWhat do you think? I've see someone did it, but no schemas or ...
I am programming Blue Pill stm32f103c8t6 mcu, and I am having troubles implementing I2C driver for it. I have tried one I2C example from one site, then tried to implement it on my own by datasheet, yet it does not work - it does not generate START.I ...
Hello,I have 2 piece stm32f407 board. i try to communicate them with I2C. One of them is master, other one slave. i tied 4.7k pull up resistors.when i feed slave board with usb cablo (debug cablo),master generates "start" condition and slave answers....
How to use the timer to keep our LED on 80% to 10% (linear down) of the time by setting a period of 500X, turning it on when the counter is 0 to 400X (0-15 minutes) and turning it off when it is 400X to 500X(5 minutes)?The time and period is a draft ...
My question here is this: Can the STM32G4x1 line access external flash memory (e.g., via QuadSPI)?My confusion is as follows: the following page:https://www.st.com/en/microcontrollers-microprocessors/stm32g4-series.htmlintroduces the STM32G4x1, G4x...
I've used stm32F103VC before, so this time I changed my MCU to stm32F103RC. I saw in the datasheet that the specifications of the two chips are almost equal.However, I cannot properly set the timer in stm32F103RC.Here's how I tested it:I make a clock...
I've picked up two discovery f3 board and configured to toggle a pin(in irq timer handler) everytime ARR=17999 on TIM2 with a clock of 36Mhz, derived from HSE crystal on board. If i connect the two pin to an oscilloscope i notice a drift between the ...
Hi all,I have developed a program with NUCLEO-H743ZI (Version 1).And there is no problem for debugging. Recently, I bought NUCLEO-H743ZI2 (Version 2). I found it cannot enter main function in the first beginning. I try to uncheck 'run to main' item ...
