ESP8266_Wireless remote control pen power terminal 3.0V

Overview

Compatible with the new version of ESP8266 wireless remote control pen power board 2.0V, it replaces the new power management chip to solve the heating problem and extend the use time.

The power management chip uses TA4056A. Compared with the previous version, the 5v boost circuit has been deleted, which reduces power consumption and solves the heating problem. When using this version, you need to pay attention to the resistance of R1. The resistance of the ground resistor determines the effect of TA4056A on The reference for the battery charging current is as follows:

I recommend choosing a resistance value between 10-5K to take into account the charging speed and try not to excessively damage the battery.

There is an error in the asynchronous transmission and reception of msp430f147. I have a program. Please help me.
There are two msp430f147 for asynchronous communication. One is for sending and the other is for receiving. The sending is to send 65 continuously, and the receiving is to store 65 in a fixed position
