The crystal oscillator of the 51 single-chip microcomputer is: 11.09520MHZ. If you want to generate a baud rate of 9600bps, here is the formula I found on the Internet: Baud rate = 1/16 or 1/32*(frequ...
This is how the teacher taught us microcontrollers (reposted) Seeing that many netizens are asking how to improve their abilities, I would like to talk about my own learning process. I studied communi...
I have a 10-year-old laptop with an I5 CPU and 4G memory. I haven't used it for two or three years. The day before yesterday, I turned it on. It took about 10 minutes from booting to running. After bo...
Some time ago, I needed to test the charging of a lithium battery pack. The voltage of 18 lithium batteries in series can reach more than 70V. I used to have a GPC-6030D linear adjustable power supply...
Thanks to Shaolin for the win32 demo program. I looked at the files debugged with arm-elf-insight in the code base. Because insight is hard to find under win, I tried debugging with slickedit+qemu. I ...
The communication of F2808 is in CAN self-test mode, and the program runs normally. The data sent and received are normal. However, when it is changed to normal eCAN mode, the program hangs at the wai...
