rcc boots

Believe that a lot of new and old customers who use the Win7 system, whether ever or now, have also encountered such a situation, the computer boot up after the Supervisory.exe application error box, immediately let their silly eyes, really is to

Hold down the chassis power button, observe the CPU cooling fan turned a few laps, it stopped, and then turn a few laps and stop wish repeatedly so, is not open machine. The same is true with the lights on the chassis. Light it up and extinguish it.

The systeminit () function appears in the first line of the main () function. We can see its importance. Previously, the systeminit () function has never been concerned, but only knows that it is a function for initializing the stm32 system. Today, I decided to take a closer look and start learning stm32 again. This function is in system_stm32f10x.c. The C file is mainly used for hardware configuration. /** @addtogroup STM32F10x_System_Private_Functions * @{ *//** * @brief Setup the microc

Gd32 is a fully compatible Cortex-M3 processor of stm32 series, which is made by Zhao Yi INNOVATION company. It has several highlights:1,High clock speed 108 MHz. Performance is improved by more than 30%, and super-frequency to 120 MHz is supported2,Flash Zero Wait. The MHz of stm32 requires two waits. In fact, zhaoyi INNOVATION company started out as flash and owns gflash patents.3,Using arm Cortex-M3 new kernel r2p1. Stm32 adopts r1p1 with some defects4,Cost-effective. Gd32 is generally 20% ch

Capture principleLook at the system block diagram, today using frequency division to collect waveforms, the official provision of the routine is not configured timebase parameters, there is no crossover, the advantage of crossover is not very real-time to obtain the waveform, so as to provide accuracy (can be said to calculate the average). Capture the external 8 pulses, read the value of the count before and after, th
