I learned 51 and I am currently playing with 51. Now I want to play with PIC or AVR microcontrollers. I want to ask everyone: What are the mainstream models of PIC and AVR microcontrollers? What are t...
Hello colleagues, I want to make a development board. There are so many of them on the market. I wonder what kind of development board you think you are still missing. Could you please take some time ...
First of all, the reading and writing of K9F1208 on the circuit and any operation are completely normal. Now I remove the FLASH chip on the circuit board, and then use a wire (about 10CM) to lead out ...

For the voltage regulator modules (VRMs) that power the latest computer central processing units (CPUs), power supply designers have historically used multiphase interleaved b...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
