"Recommend Chinese Chip" + Qinheng CH579 [Copy link]

 

 

Smart home applications are very popular now, and MCUs with integrated Bluetooth are widely used. In this application, the domestic Qinheng CH579 is such a Bluetooth MCU.

CH579 is an ARM core 32-bit microcontroller with integrated BLE wireless communication. It integrates low-power Bluetooth BLE communication module, Ethernet controller and transceiver, full-speed USB host and device controller and transceiver, segment LCD driver module, ADC, touch button detection module, RTC and other rich peripheral resources.

Qinheng's MCUs are very unique and have their own development path

Does CH have M4 series?

It seems that there is no M4, only M3. In addition, Qinheng has launched a 32-bit MCU based on RISC-V, the CH32V103 series. You can try it if you have a chance.

Good suggestion, you can try it.

Nice chips!!!

Additional content (2020-7-27 10:04): Very good. Additional content (2020-7-27 10:06): The Bluetooth examples are very comprehensive. It can also run Ethernet. The price is also good. The size is also small. Great! Additional content (2020-7-27 10:07): I ran Bluetooth yesterday. It provides three ways to download programs: serial port, ISP SWD of USB port (can be simulated). It can be debugged with STLINK. Haha.

Built-in 10m phy? This chip design is so down-to-earth, great.

Yes, the peripherals are quite rich and very useful for running some light applications.

The built-in PHY is really a highlight of CH579 (other manufacturers' M4 may not include PHY), which makes it much easier to draw the board. In addition, the original manufacturer also provides a wealth of SAMPLE CODE. I tested the MQTT_PUB and MQTT_SUB in the source code provided by the original manufacturer and found that they can successfully connect to the external network broker.

The review is very good. I look forward to sharing more experiences of CH579.

Yes, judging by the official package, the drivers and apps are pretty comprehensive
