DINGHOME_HK32F103

Overview

3-11:

There is a predecessor version. The first version could not output from the microphone to the power amplifier. The hole position was a little crooked, so the circuit was changed. The second version of the op amp amplifier has output, but the height seems to be a little higher when using a DIP40 compatible development board.

3-30:

This project has been temporarily completed for two-thirds. Although the process has some twists and turns, it was perfected during the Qingming Festival. Now it has realized Tmall Genie control and wired voice call functions. The video will be made up today (it may be at night, which is not convenient for the company). If the electric lock is not controlled at home, use an onboard LED instead. The 485 communication is still not done yet (there is a slight problem with the circuit. After searching for the problem for a long time, I found that there is no level conversion 5V-3V).

Project development process:

Familiar with HK chips, get the official library for development, and write user drivers (serial port, I2C, GPIO)
I thought that the TB-02 Bluetooth module can be programmed and debugged by connecting to the serial port of Anxinker's development board. However, it turns out that the RTS and DTR level signals need to be given to reset and SWS before programming. After continuous testing (the module is also a real product of DFN It’s hard to know the faulty soldering (I changed 2 boards before I figured out the pattern). The firmware has been compiled and put in the attachment. I wrote a docking module data API that everyone can use. If it is paired, it needs to be re-paired. The PD2 is grounded and long pressed on the serial port to pop up. 'factoy' and then restart. It is recommended to erase the entire chip first and then burn it and then burn the triplet. The triplet needs to be applied on the Alibaba Cloud Life IoT platform. The method can be referenced in an article written by Anxin on CSDN.
After debugging, I will try it at home. I plan to go back during Qingming Festival to try it.
