[table=98%,rgb(238, 238, 238)] [tr][td]Use uboot instead of eboot. I modified uboot to support booting wince/linux/android series, support INAND/SDMMC to start wince. Do I need to comply with regulati...
I want to make an RPC remote function call module based on ARM embedded system. I wrote a small test program using the template generated by RPCGEN, but I don't know how to port it to the development ...
Hi everyone, last time I wrote a [[url=http://www.kaleidscope.cn:1020/archives/2678][b]ZigBee whitelist solution[/b][/url]], many friends have asked me to make a module related to channels, PANID and ...
A very simple circuit is to connect the 4 SPI ports of X5043 to the SPI of ARM (using STM32). X5043 is powered by 3.3V and the reset threshold is 2.7V. After powering on, it does nothing. The Reset pi...
Calibrators are widely used in university experiments. Among them, there are two experiments in nuclear physics experiments in modern physics experiments (GM counter and β absorption) that require ...[Details]
