[size=4]If you know about mobile power banks, you should know that the lithium-ion batteries inside mobile power banks can be divided into two categories, liquid lithium-ion batteries (LIB) and polyme...
I have two platforms, one passed, the other failed, I don't know what's going on? The original file overwriting method is indeed very convenient, but it seems that it doesn't work if the file is a lit...
The frequency divider 74LS163 does not work. What is the reason? I passed the clock signal generated by the crystal oscillator through the 74LS163, and wanted to use it to divide the frequency, but I ...
I use PCF8563 clock chip on F43x, and can operate the chip (read/write) normally through I2C. But when the values written into "control/status register 1/2" (device subaddress 0x00, 0x01) are all 0x00...
