I use CH7005 to convert LCD signal to VGA output. It can output in VGA at 640*480 resolution, but it cannot output in 800*600 resolution. [color=#0000FF]The relevant registry configuration for 640*480...
Last time (https://bbs.eeworld.com.cn/thread-440392-1-1.html) we explored a particularly interesting MSP430 property: Although the MSP430 has a wide supply voltage range (1.8 to 3.6V), power consumpti...
I pay close attention to the development of chips in my country. What particularly touched me was our own chip, the Loongson. As for Loongson, I may only know it superficially, not from a technical pe...
