I would like to ask, how to calculate the switching frequency of MOS tube? For example, in the figure below, the optocoupler is 521 and the MOS tube is 3205. What is the highest switching frequency of...
[size=4] The ADC12 module of the MSP430 microcontroller is a 12-bit precision A/D conversion module, which has the characteristics of high speed and versatility. Most of them have built-in ADC modules...
[b] [/b] I reviewed the use of 430g2 these days. I found something abnormal. The teaching video of the first lesson "Introduction to the Value Line Series" under "Teaching you how to use MSP430ValueLi...
Is there any requirement for the length of the data packet of the serial port? For example, ACK 00 00 means that the data has been received, rather than a long string of numbers....
We live in an analog world dominated by digital processing, but that could be changing. Domain specificity and the desire for ever-higher levels of optimization could give analog computing some signi...[Details]
To operate OLED, connect to OLED through three lines (SCK, DO, CS). There is no DI here because 2440 will only transmit data to OLED without receiving data. gpio_spi.c implements gpio simulation spi ...[Details]
The latest research report released by Strategy Analytics pointed out that global smartwatch shipments in Q2 2019 increased by 44% year-on-year to 12 million. Apple Watch maintained the first place w...[Details]

iPad2 was launched amid the anticipation of Apple fans around the world, and is expected to continue Apple's legend. A piece of news not long ago also made the medical field, which has nothing to d...[Details]
After studying STM32 for a while, I always encounter various problems when debugging programs. I specially started a blog here to record the various problems encountered and their solutions. ...[Details]
1. Introduction to STM32CubeMX STM32CubeMX is a graphical configuration tool for STM32 chips that STMicroelectronics has strongly recommended in recent years. It allows users to generate C initializa...[Details]
The principle of the two-wire transmitter is to use the 4~20mA signal to provide itself with power. If the transmitter's own power consumption is greater than 4mA, it will be impossible to output the ...[Details]
