[Diao Ye learns programming] Arduino hands-on (197) --- zero knowledge STM32F103RBT6 standard development board 2

The reference to 37 sensors and modules has been widely circulated on the Internet. In fact, there must be more than 37 sensor modules compatible with Arduino. In view of the fact that I have accumulated some sensor and actuator modules on hand, in accordance with the concept of true knowledge (must be hands-on), for the purpose of learning and communication, here I am going to try and do more experiments one by one. Whether it is successful or not, it will be recorded ——Small progress or unsolvable problems, I hope to be able to throw bricks and spark jade.

Zero Knowledge Laboratory is a non-profit laboratory for researching cutting-edge electronic application technology, and focuses on open source and promotion of electronic technology, so that people can learn electronic technology more easily and happily. It has a complete and powerful team, including embedded hardware, embedded software, Technical engineers and senior project leaders in the front and back of the website.

Zero Knowledge Lab is committed to building an open source platform for China's local software and hardware. Through this open platform, whether it is electronics enthusiasts, makers and smart hardware developers with professional knowledge background, or children and amateurs without professional knowledge background , can easily complete the rapid realization from idea to prototype. At the same time, we focus on the application of wireless technologies such as WIFI, BLE, ZigBee and other common sensors in the Internet of Things, such as temperature and humidity, attitude, image, color, sound and other modules. With our help, your smart hardware products will be able to obtain various sensor data Easier, easier to connect to the network.

The Zero Knowledge standard board developed by Zero Knowledge Lab has been officially released. The Zero Knowledge standard board adopts the same frame design as the Arduino UNO, so the size is exactly the same as it, and the pin interface is also fully compatible with the UNO. The Zero Knowledge standard board uses STM32F103RBT6 as the MCU, adopts a 32-bit high-performance ARM core, and makes its operating frequency up to 72MHz; has a large storage space-20KB RAM, 128KB FLASH; includes 37 IO pins, 15-way PWM, 15-way ADC (12-bit precision), a USB device interface, and a USB-to-serial device interface; USB, AC-DC adapter, LI-PO and other ways of power supply can be used; at the same time, the Zero-Knowledge standard board and the Zero-Knowledge development tool can realize a Key download, very convenient to use.

Click OK, and then you can see the following interface, and the example is also displayed normally, indicating that the installation is normal:
