Burn MQTT firmware

Overview

Alibaba IoT Studio is an IoT development platform that can be used to quickly build cloud-based IoT applications. It provides a wealth of IoT components and tools, allowing developers to easily perform operations such as device access, data storage, and data analysis. To achieve Web visualization, you can develop through the data visualization components in IoT Studio. First, you need to connect the device to the IoT Studio platform. You can choose to use Alibaba Cloud IoT Suite, MQTT, and other methods to connect. After the connection, the data reported by the device can be received and stored by the IoT Studio platform. By connecting to the Alibaba IoT Studio platform, combined with data visualization components and Web technology, real-time monitoring and control of IoT devices can be achieved.

Send a command to test, for example, send humidity 49.

AT+MQTTPUB=0,"/sys/a1ZCbJN0kQB/4WpGE15ik3MbGt0lEiIj/thing/event/property/post","{params:{"CurrentHumidity":49}}",0,0

You can see that the data can be displayed normally.

STM32 multiple serial ports share printf to print serial port data

(1) Problem description: For multiple serial ports to share the printf function, most of the information found on Baidu suggests rewriting a xx_printf(format, ...). However, it is still inconvenient to use. As far as this problem is concerned, adding a judgment statement can solve it. (2) Solution: The printf func

stm32: query method using pt2262/pt2272 wireless module

The working principle of pt2262/pt2272 is that after pressing the button of the remote control, a high level will be generated on the corresponding pin of the receiver. The function realized by this program is that after the remote control is pressed, the red light will light up. The query method is used to detect whe

Question about using printf function in stm32

If you want to use printf in mdk, you need to redefine the fputc function and avoid using semihosting (semihosting mode). The default output device of the standard library function is the display. To output to the serial port or LCD, you must redefine the functions related to the output device called in the standard

STM32 RCC principle

1. Clock source In STM32, there are 5 clock sources, namely HSI, HSE, LSI, LSE, and PLL. ①HSI is a high-speed internal clock, RC oscillator, with a frequency of 8MHz; ②HSE is a high-speed external clock, which can be connected to a quartz/ceramic resonator or an external clock source, with a frequency range of
