When Amazon quietly launched a product called Elastic Computing Cloud 12 years ago, the Internet industry in China, across the ocean, also ushered in an unprecedented development opportunity. Let's...[Details]
The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]
OSC_IN and OSC_OUT are external crystal pins by default. If you do not use an external crystal oscillator on the STM32, how to connect OSC_IN and OSC_OUT If you use the internal RC oscillator instead...[Details]
I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
DMA： 1. When using DAC, when the converted analog signal is output through the IO port, why is the IO port also configured to input mode? PS: The stm32 manual defines that PA4 and PA5 are connected...[Details]
Design a second and minute pulse generator for a single-chip microcomputer using the interrupt method. Assume that P1.0 generates a positive pulse of one machine cycle per second, and P1.1 generates ...[Details]
