I got a little gecko M0 development board EFM32ZG, the legendary ultra-low power consumption, with a MemoryLCD that is said to be more advanced than an e-paper display: LS013B7DH03, quite high-end. Th...
[hide]作为一种新的光源,近年来各大公司和研究机构对LED电源和驱动电路的研究方兴未艾。与荧光灯的电子镇流器不同,LED驱动电路的主要功能是将交流电压转换为直流电压,并同时完成与LED的电压和电流的匹配。随着硅集成电路电源电压的直线下降,LED 工作电压越来越多地处于电源输出电压的最佳区间,大多数为低电压 IC 供电的技术也都适用于为LED,特别是大功率 LED供电。再则,LED电源还应能利用...
There is a problem when using memcpy in my program. pBufOut is a BYTE pointer, and pbuf is an array of local variables. BYTE pbuf[40]; memcpy( pBufOut, pbuf + 3, 32 ); After executing memcpy, a lot of...
When adjusting EEPROM (IIC), the first time the program is run after the board is powered on, it can run normally. However, when the program is downloaded again and run again, the Serial Bus is always...
There was a small event in the forum some time ago (we don't produce code, we are FPGA code porters [url]https://bbs.eeworld.com.cn/forum.php?mod=viewthread&tid=467513&fromuid=391494[/url]) Everyone w...
