In the past few days, the news that ZTE was "banned" by the US Department of Commerce has triggered widespread reflection and concern in various domestic industries about the lack of independent co...[Details]

In the previous article, I wrote a simple GPIO running light test, which looked a bit monotonous. I was used to serial port debugging. If there was no serial port on the board, I had to find another ...[Details]

In 1952, Bell Labs built a 6-foot-tall automatic number recognition machine called "Audrey", which could recognize the pronunciation of the numbers 0 to 9 with an accuracy of more than 90%. And its...[Details]

As many companies listed with the concept of touch screen begin to "transform and upgrade", the official voice of the TP industry is getting smaller and smaller. At the same time, the list o...[Details]

1. Heart rate measurement principle 1. What is a heart rate module? The heart rate module is professionally used to monitor the heart rate of the wrist, fingers, forehead, earlobe, chest and other ...[Details]

Independent watchdog (IWDG) and low power mode are often used in STM32 development. The watchdog is to detect and solve faults caused by software errors, and the low power mode is to enter sleep mode...[Details]

Ouster LiDAR OS-1 (left) and OS-2 (center) Velodyne invented the modern 3D LiDAR scanner in the mid-2000s, but in recent years conventional wisdom has held that Velodyne’s design — 64 lasers mounted...[Details]

A crystal oscillator can be electrically equivalent to a two-terminal network consisting of a capacitor and a resistor in parallel and a capacitor in series. In electrical engineering, this network h...[Details]

1) ADC multi-channel acquisition: (Multi-channel acquisition must use scanning mode. In scanning mode, the channels of the rule group share a register, so DMA transmission must be used; to prevent da...[Details]

Note: This STM32 microcontroller is the STM32F103 series. The ADC of Stm32 has DMA function. This is beyond doubt and is what we use most! However, if we want to sample a signal (such as a pulse sign...[Details]

The key is the configuration of registers. The T1 timer (16 bits) of CC2530 needs to configure three registers: T1CTL, T1STAT, IRCON Here is just a brief introduction. For more details, please refer ...[Details]
