Measuring oscilloscope output ripple and dynamic response of low voltage (<1V)/high current (30-150A) power supplies has always been a challenge, with each new setup bringing its own errors. Errors in...
I am using the YLS3C2440 development board recently and I am going to use a GPRS module. This module is a USB to serial port. I connected it to the development board through the USB port and connected...
I am curious. There is no code. Can it adapt to motors with different parameters? I plan to learn more at the TI live on September 26.TI launches the industry's first codeless, sensorless FOC 70W BLDC...
Currently, ST BlueNRG -LP has realized the pairing function as a slave, in which pairing can be initiated by both the host and the slave. How can I prohibit the host from initiating pairing?...
According to my weekly plan, I have to build a circuit to power the microcontroller. Then I designed a 5V circuit diagram last time. I found a few resistors that are closest to the voltage. I soldered...
For STM32, there are two ways to reset the software: 1) Use the official software library The system reset function is directly provided in the stm32f10x_nvic.c file of the official software li...[Details]
Because the STM32 HAL library only has millisecond-level delay for HAl_Delay(), in order to achieve accurate microsecond-level delay, Systick has to be modified. However, since it is used internally ...[Details]

This program uses the eight-channel ADC single acquisition mode. According to the configuration, ADC12SC will automatically reset after the conversion is completed in the single mode, so it is necess...[Details]
In 1949, after three years of civil war, the Nationalist government was defeated and retreated to Taiwan. The political and academic circles launched a large-scale reflection on why they failed in ...[Details]
The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[Details]
Use the STM32 timer input capture module to control 3-way ultrasonic sensors. The ultrasonic sensor used this time is the common HC-SR04, which is often used in the obstacle avoidance system of smal...[Details]
1. Common knowledge about DMA. 1. Function: to achieve high-speed data transmission between chips. That is, it can achieve data transmission without occupying the CPU. 2. Mode: There are three tran...[Details]
The code for using timer 0 to implement a running light in a 51 MCU is as follows. The LED light is connected to port P1. The code is annotated below, so I won't explain it in detail. My English is n...[Details]
Title: Use two dynamic digital tubes to display from 0 to 60, output from the P1 port of 89C51, without adding a decoder, and directly connect the digital tubes. Note that they are dynamic digital tu...[Details]
