Working principle: The circuit is shown in the figure. After the 220V mains is stepped down by transformer T and rectified by VD1, a DC voltage of about 9V is obtained on capacitor C1. This voltage ch
The first line of the LCD screen shows the clock, for example, 5h40m45s. When it is just started, it is 0h0m0s. You can set the time by pressing a button. The next line shows the stopwatch unit in s.
Asking for a friend: Who has an ADI emulator? ? It can be a BF53X compatible one, new or second-hand, I hope it is cheap, easy to use, and has all the accessories :)
Hey guys! Yesterday I made a QX2303 boost circuit, following the circuit and recommended components in the manual:Input capacitance = output capacitance = 22uFInductance = 47uHSwitching tube: 1N5819Th
As a low-power 16-bit chip, msp430 has greatly improved functions compared to 8-bit MCU. I bought msp430 in a group purchase last time and saw its power. However, the IO port and FLASH were small, so
