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...
Posted on April 24, 2013 at 15:59 Hi, all. I working at ADC sampler implementation. ADCsamplerhas a next flow: Timer 1 generate sample rate at 200kHz.At every Timer 1 CC2 interrupt ADC1,ADC2,ADC3 take a sample.DMA is used to transfer s...
Posted on April 24, 2013 at 23:09Hi,i'm studying about GPIOs on STM32F4 Discovery but in the User Manual i don't understand very well how GPIOs work.Can someone helps me to understand how it works?GPIOs should be 9 ports of 16 bits that SoC uses to ...

Posted on April 24, 2013 at 11:05Hi all,plz i need to generate a signal like this one to control a stepper motor: if you have an idea don't hesitate plz. I found an example named ''6 steps'' which contains a signal like this one but it doesn't work
Posted on February 13, 2012 at 20:16Hello,I have a little problem with Rx on stm32f417.I designed my own board, byt i am putting this here, becouse i cannot find another approperiate forum.I tried to set up UART2, but i cannot make reciving working....
Posted on April 18, 2013 at 12:20Hello!Can i mesure period of High Speed External (HSE) oscillator period with help of DWT?I initialized DWT and can mesure number of cycles of operations.I use stm32f207 microcontroller.Thanks in advice.p.s. Or mayb...
Posted on April 24, 2013 at 13:33Hello everybody, I ever look on webside if previous post treat my problem, but they not resolve my pb. The problem is, I try to pramreter the TIM1 PWM output on STM32, but it do not work. The TIM1 counter register CN...
Posted on April 19, 2013 at 16:09Hi,I need to replace a 5V-uC by a 3.3V type and maybe it will be a STM32F0xxx. Now there is one question concerning 5V tolerance: If the 3.3V-uC drives an output that has a pullup resistor to 5V, is that any problem ...
Posted on April 19, 2013 at 05:54I'm working on a project use a F4 MCU. Its clock speed is 168MHZ. The resolution of my LCD is 320 * 480. After some testing, I got some figures. Rendering a full screen by direct accessing LCD controller by MCU can r...
Posted on April 23, 2013 at 16:37Hello, I'm using STM32F207 on a Olimex board. I wired a Microchip EEPROM (24LC512) to PF0 and PF1 to use with I2C2. The problem I have is that in sEE_WritePage() I cannot get pass the I2C_Send7bitAddress(sEE_I2C, sEE...
