General catalogue Construction of single chip microcomputer HLK-W801 development environment Single chip microcomputer - HLK-W801 Bluetooth BLE function test Yesterday, the demo ran clearly. Today, let's take a look at the LED of the development board lit by the mobile phone through Bluetooth remote control. Although this is not a typical use ...

1. Basic principles In fact, driving the LCD is to write data to the LCD display memory. The place where 1 is written is displayed, and the place where 0 is written is not displayed. The reverse display is just the opposite; Since the video memory is distributed in 128 columns and 64 rows, it is also called 12864 liquid crystal. 2. Basic char ...

First met LoRa In short, LoRa is a low-power remote wireless communication technology. It is a wireless data transmission module developed based on SX1276/1278 chip of Semtech company. This chip has small integration scale and high efficiency, so that LoRa module has high receiving sensitivity. So what are its advantages over our commonly ...

The previous chapter introduced the weather forecast machine built under ESP8266. At that time, the results contained some Chinese garbled codes. Today, I try to solve this problem. The problems involved here include the following steps: First, convert the string of utf-8 into gbk encoding,Then find the corresponding lattice data by looking up ...
