After getting the development board, I found that the board has a lot of peripheral circuits, and the interfaces are very rich. In particular, the main controller integrates WLAN and 2.4GHZ wireless f...
Hehe~ I always feel like there are too many capable people in a forum like this, and I usually don’t dare to speak up~~ Huhu~ I can finally breathe a sigh of relief. Newcomer, let me report in~ Hello,...
It is a virus that infects a USB flash drive. An autorun.inf file appears in the D disk. At the same time, when you right-click the D disk, there will be an additional "browse" item. The content of th...

The CPU is STM32F103CB, without operating system. Receive data from GPRS through UART1 and process it in the interrupt function USART1_IRQHandler unsigned char a_GPRSData[500]; unsigned int g_DataLeng...
I recently used MSP430FR5949 and found that when the serial port baud rate was 115200, the MCU woke up from LMP3 and received data incorrectly. The reason was probably that the start bit was judged in...

The reason for the light decay of white LEDs: the decline of phosphor performance
So far, the rapid decline of the luminous performance of white light LEDs, especially low-power white light LE...[Details]
1. Principle of displacement angle sensor
The angle sensor is used to detect angles. It has a hole in its body that fits the LEGO axle. When connected to the RCX, the angle sensor counts once ...[Details]
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
