DS1302 is used as external clock, and the digital tube is used for display. The segment selection of the digital tube uses a 74LS164 to output serial data in parallel. Can this serial data be output u...
Regarding the sd24 of msp430, I checked online. Some people say it has 24-bit precision, while others say it is actually 18-bit precision. Has anyone done 24-bit precision? If 24-bit precision can be ...
I tried to allocate free space in fat1 and fat2, and then add items to the dir root directory item, with the goal of creating a new file named xxxxxxx.txt in the C drive. I tried to assign values to e...
I am working on something with an SD card on it. The SD card has pins connected to the WinCE system, so that the SD card is visible in the WinCE system. Now it is equivalent to the SD card being share...
Hey guys, I'm learning embedded system recently, using ARM7 S3C44BOX, and I've encountered a problem recently. I want to download data from CF card to host, but after inserting CF card into test machi...
I would like to ask if anyone has made a bootloader for pxa310 or pxa270. It requires booting nk.bin from a CF card. What software should I use to compile it? Should I use wce6.0 or AXD provided by AR...
