I have designed a version of the expansion board for the BB board before, [url]https://bbs.eeworld.com.cn/thread-376965-1-1.html[/url], and the pins of the BB board and the BBB board are exactly the s...
When calculating the circuit branch current and component voltage, using the loop current method, how do you determine whether the selected loop group is an independent loop? Is there any specific sel...
I would like to ask if I do not process the serial port receiving and sending in the interrupt, but do it in the main program. I know that if I want to determine whether the serial port has received a...
For a "naked" system, the use of interrupts is unavoidable. The interrupt operation functions of the Stellaris peripheral driver library are encapsulated in the .c/h files and interrupt.c/h files of t...
