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 June 24, 2016 at 13:35 Hi everyone! I have a problem getting the RTC of a STM32L151C8 device to work properly. I am using a custom board with an 8MHz external oscillator and the SPL which works fine so far. I used the i...

Posted on June 24, 2016 at 05:03I am working on a personal project and keep running into a problem. The I am trying to use the DMA in an STM32F4 to control a strip of LEDs that rely on the duty cycle of an output signal.I want to update the duty cyc...
Posted on July 26, 2013 at 05:16I have a motor with a quadrature encoder and I want to get the relative (absolute after counting from home position) position. I tried getting the encoder count using an interrupt from one channel of the encoder and c...
Posted on June 04, 2016 at 05:32Hi everybody,I got a problem to implement USB CDC to STM32F407IG. Although looking into all the post here, still not solve my problem.I am using self-made board with STM32F407IGT6, The sch is simply connect as MCU US...
Posted on June 23, 2016 at 21:54I want to measure how long a signal is high as accurately as possible (preferably down to the microsecond). I started by triggering an EXTI interrupt one both the rising and falling edge of the signal. The EXTI handle...
Posted on June 23, 2016 at 20:11 I am working on getting familiar with the STM32F411 using ST evaluation board STM32F411E-DISCOVERY. I have written the following code using Eclipse + Ac6 STM32 + gcc (arm-none-eabi5.3 2016q1) I am a...
