SWD offline programmer

This project uses STM32F103RET6 as the main control, and is modified based on ST's official CMSIS-DAP project to achieve offline and read-protected programming (because the project currently only has F103 series offline programming requirements, so only F103 programming is temporarily added. write algorithm).

IoT entry-level example based on MQTT message communication: GD32E231+ESP8266 implements Wi-Fi remote temperature and humidity collection, control and network clock

This solution is based on the GD32E231 Cortex-M23 core MCU as the main control. The Wi-Fi module uses Essence's ESP8266 and is developed for secondary use. The LCD screen using the SPI interface displays relevant information. The peripheral circuit part uses simple LED lights. Buttons and sensors to complete the demonstration function with the MQTT server.

Open source power meter: with power supply function, dedicated to IoT power consumption measurement

The biggest feature of testing the power consumption of IoT devices is the high dynamic range, a few uA in the sleep state and hundreds of mA in the transmitting state, and it supports dynamic switching of the measurement range. The open source power meter ZS1100A has a dynamic measurement range of 1uA to 1.5A, a resolution of 100nA, and an accuracy of 1% ± 200 nA, which is very good.

Sony's super powerful IoT kit based on its own CXD5602 (open source information)

The biggest highlight of this kit is Sony's own 6-core microcontroller CXD5602, which comes with 1.5MB of general-purpose SRAM, 64KB of backup SRAM, and a main frequency of 156MHz. There is also an M0+ core assist processor for IO control management, which comes with 256KB of general-purpose SRAM. The built-in GNSS receiver supports GPS and GLONASS. Others include 2D graphics acceleration (supporting rotation, scaling, mixing, etc.); dedicated sensor acquisition peripherals (with its own 40KB FIFO and supporting preprocessing) supporting SPI, I2C and other interface methods; DCMI camera interface and I2S audio peripherals All pretty good too.
