What is the difference between a stepper motor driver chip and a DC motor driver chip? In terms of input and output? Can a stepper motor driver directly drive a DC motor? What is a linear drive and wh...
Abstract : This paper briefly introduces the principle of infrared remote control transmitting and receiving system, and gives a clever implementation method of using 89C2051 as a decoder of remote co...
1. Principle 1. Infrared emission protocol There are many infrared communication protocols. This experiment uses the NEC protocol. This protocol uses PWM modulation and uses pulse width to represen...[Details]
Today, under the guidance of a low-level expert, I learned how to configure the PWM module! Woof! First open the file configured last time, as follows: Then, we need to use TIM1 to set PWM: Then,...[Details]
Function List and Notes (lower-level driver part) 1. IO port initialization: control IO and communication IO. Control includes power control, reset and low power mode. Communication is the serial po...[Details]
When designing a product, if the application environment's requirements for power isolation are not considered, the product will be unstable due to improper design, and even high voltage may damage t...[Details]

From the functional classification, it can be divided into: 1. Active control ADAS: ACC/AEB/LKS, etc. 2. Warning ADAS: FCW/LDW/PCW, etc. 3. Other auxiliary ADAS: BSD/ADB/panora...[Details]
1. Function and purpose There are two pins BOOT0 and BOOT1 on each STM32 chip. The level status of these two pins when the chip is reset determines which area the program starts from after th...[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]
12864 LCD parallel port driver is more commonly used, but considering that sometimes the IO port of the microcontroller or MCU is limited, the serial driver method can be used. The following is ...[Details]
The T3 timer (8-bit) of CC2530 requires understanding of T3CTL, T3CCTL0, T3CC0, T3CCTL1, and T3CC registers. Timer 3/4 is an 8-bit timer with timer/counter/PWM functions. Timer 2, also known as MAC t...[Details]
Since 2018, the field of artificial intelligence chips has been very lively. Especially in China, the rich vertical application scenarios have provided fertile ground for the development of AI chip...[Details]
By manually inputting single pulses to the /INT0 of the 8051 microcontroller one by one, an interrupt is requested to the microcontroller. Each time the microcontroller interrupts, it outputs 55H, AA...[Details]
