The LM2596 series regulators are monolithic integrated circuits that provide all active functions for a step-down (buck) switching regulator capable of driving 3-A loads with excellent line and load r...
I wrote a program that uses the TIM3 timer interrupt of the STM32F103RCT6 microcontroller to refresh the OLED display screen to display the time of the DS1302. Then the delay function in the main func...
Although the stability of LED lights has reached a relatively good level recently , some products have problems with light decay and color drift, mainly due to unreasonable heat dissipation design. R...[Details]
On October 26, Redmi officially announced that the 100-megapixel camera has officially returned to the Note 11 series. It is reported that the 100-megapixel imaging technology of the Redmi No...[Details]
With the improvement of living standards, televisions have gradually become part of people's lives and have become an indispensable household appliance in daily life. However, there is still radiat...[Details]
【Abstract】 Using DSP and CPLD to design a broadband signal source, the flexibility of DSP software control and the high speed, high integration and programmability of CPLD hardware are organically ...[Details]
When the WDP500-2A plane grating monochromator is used to test the emission wavelength of a high-power laser diode at different currents, the matching of the laser diode has the disadvantages of lo...[Details]
This article is translated from Tomshardware PAM4 for DRAM At a press conference last week, Micron shared some additional details about the latest GDDR 6x SGDRAM used by Nvidia's GeForce RTX30 s...[Details]
At present, solid-state low-light devices are mainly EBCCD and EMCCD devices. With the development of CMOS process and circuit design technology, the performance of low-light CMOS image sensors i...[Details]
This application note discusses
the impact of
the phase frequency detector (PFD
) specifications on the phase-locked loop (PLL) dead-zone and jitter performance. In a PLL design using charge pump...[Details]
As a new high-level programming language, C language has a wide range of applications and implementations in computer software programming. Below, I will introduce the usage of bit in C language in...[Details]
Translated from——spectrum When we saw the wonderful scene in the movie "I, Robot" shot by Will Smith in 2004, where he drove a very sci-fi Audi RSQ sports car to fight against robots, it still clea...[Details]
TCL Huaxing, Sanan Optoelectronics, and Konka's three billion-yuan projects have made new progress, and Xinhuazhang has received a new round of financing of nearly 100 million yuan This week, the 42....[Details]
