At present, the MCU sends data to 8563 correctly, but the MCU reads the data from 8563 incorrectly. It was FF at first, and then it became 00 after changing the program. I don't know where the problem...
I am now using STM32F103 with an external ADC to sample data from a 16-bit pressure sensor. Iplan to use SPI2's MISO (input only), SCLK (output), and CS (always low, controlled by other IO ports)in sc...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]

1 The significance of using RTOS on MSP430
It is understandable that it is meaningless to use RTOS on MSP430. Because the hardware resources of MSP430 are limited (for exampl...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
DSP (digital signal processor) is used more and more frequently in today's engineering applications. There are three main reasons for this: first, it has powerful computing power and is capable of ...[Details]

July 11, 2012, Beijing - Altera Corporation (NASDAQ: ALTR) today announced the launch of 40-Gbps Ethernet (40GbE) and 100-Gbps Ethernet (100GbE) intellectual property (IP) core products. These core...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]
In the single-chip microcomputer system, in addition to display devices, sound devices are often used, and the most common sound device is the buzzer. Buzzers are generally used for some low-demand...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
The TPS92210 is a single-stage LED lighting pulse width modulation (PWM) controller. The TRIAC dimmable solution not only regulates the LED current, but also achieves a power factor close to 1. The...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
At present, a large number of cooling tower fans, speed fans and special fans are in use in petroleum, chemical, pharmaceutical, metallurgical and other enterprises. Some fans have no monitoring in...[Details]
Car lights, whether headlights, fog lights or tail lights, play an important role in driving safety. However, the material of the car lights determines that the probability of damage in a collision...[Details]
a. Keep the battery clean, wipe off the spilled electrolyte, contaminated dirt and dust in time; keep the poles and terminal clamps clean and in good contact, and apply vaseline or butter to preven...[Details]
The production process of lithium batteries does not mention the previous processes such as material preparation, winding, liquid injection, and packaging, but only talks about the final formation ...[Details]
