Introduction
The PIC12CXXX microcontroller would be a great mouse controller, but it doesn't have enough I/O. You need two I/Os for the X-axis encoder, two for the Y-axis encoder, one for the serial output, and 2 or 3 I/Os for the mouse buttons, but we only have 6 I/Os. The
solution is to use A/D conversion for the buttons. 2 or 3 switches can be coded, depending on how you connect them through resistors and use A/D conversion to read the result. The A/D pin can be periodically changed to go into the coded LED. See the schematic.

[MCU Notes] Active Buzzer Driver-Efficiency Programming
![[MCU Notes] Active Buzzer Driver-Efficiency Programming](https://6.eewimg.cn/news/statics/images/loading.gif)
Buzzers are very common devices, divided into passive and active types. Choose different types of buzzers according to project requirements. In recent projects, active buzzers are used. It's still the same old routine. Draw the circuit board and then program it. The schematic diagram in the project is as follows:

Realization of Single-wire Communication of Microcontroller Based on 1-WireTM Technology
In the construction of a large-scale single-chip microcomputer application system, it is inevitable to use a multi-machine system, which often involves information exchange between systems. When the communication rate requirement is not high, we hope that the two communicating parties occupy as few port connections

PIC microcontroller A/D conversion data storage and serial port efficiency
The data after A/D conversion of PIC microcontroller usually needs to occupy two 8-bit wide RAM units, but the storage units of PIC microcontroller are limited, so the storage units of the microcontroller cannot be effectively utilized. At the same time, it takes a lot of time to transmit data to the host computer thr
