[ Thanks ] Thanks to EEWORLD and Qinheng Company for providing me with the opportunity to review this product. I would also like to thank my friends who reviewed this product together, because I learned a lot from your articles. I would also like to thank my friends who took the time to read my posts.

Time flies. It has been almost two months since I received the development board. During this evaluation process, I was generally happy because I learned new knowledge and enriched my life. Programming microcontrollers is one of the pleasures of my life, and being able to share my knowledge is even more enjoyable.

1. The overall impression of the development board is that the workmanship and materials are solid, and the development board runs stably. The official development environment Mounriver is easy to install and runs normally without freezing or abnormal exit. The compilation speed is also very fast. The download tool is also integrated. The official provides a wealth of routines with clear comments, so that people who are first exposed to this chip development can understand it at a glance. The routines provided are comprehensive, especially rich examples of Bluetooth and USB.

2. I learned to use commonly used peripherals such as GPIO, UART, I2C, SPI, ADC, BLE, and PWM. These peripherals are easy to drive and work stably.

3. Learned to use Qinheng's Bluetooth task system TMOS, and became familiar with common functions such as task creation and event-driven.

4. In terms of specific examples, I drove the OLED screen, LCD screen, serial port screen, servo, PWM drive solid-state relay, USB keyboard, etc. CH582 communicated with the mobile phone via Bluetooth, and used E4A and WeChat applet to create an APP to communicate with the development board. I made an example of a heater and uploaded related videos.

【Discussion】As a new chip, there are relatively few resources available for query and use. Basically, it is based on routine learning. The official technical support needs to be strengthened. There are still some things that need to be improved in the software, such as the idle interrupt reception of the serial port. I encountered a problem when using it, and there was no solution. There is also internal temperature acquisition, and the specific conversion formula has not been improved. The download tool is more troublesome to use, and WCH-LINK debugging is not very convenient.

[Wish] I hope that EEWORLD website will become better and better, and provide more and more learning and communication materials and routines for the majority of MCU developers. At the same time, I also hope that Qinheng's chips will become better and better, and more styles of MCU development boards can be provided for website evaluation. At the same time, I hope the epidemic will end soon, and I wish the motherland to be strong and the world to be peaceful!
