Initially, read the serial port data for processing as follows: While (1) { Data = receivebyte (); Switch (data) { Case 'A ': Function1 ()... Break; Case 'B ': ... Break; Case 'C ': ... Break; Default: Break; } } In this way, the data can only be read once, and then how to write data to the serial port cannot be read. Once it enters the display status, it is stuck in an infinite loop and cannot jump out. Refer to the lpc1114 manual to find information

just a while ago, someone suddenly asked me systick_handler (void) How does this timer interrupt handler function be defined? Based on past experience, I feel that there should be a function declaration in the bottom of the existence of something, but down with the program, has not found the corresponding definition or declaration, then exactly how systick_handler this function? Is it possible to make changes artificially? Give me the first feeling is, must be able to make changes, after all, ju

Debuginram: The program runs in RAM debugging. The program is lost after power loss according to RAM characteristics. Advantages: The program runs faster.debuginflash: Download the program to flash in debug run. Depending on the flash feature, the program still exists after the power outage, enabling offline operation. Disadvantage: The program runs slightly slower than RAM, and is not particularly significant for normal programs. This kind of debugging method is generally used in the engineerin

JZ2440 Learning Notes Chili 2015.5 Objective I started JZ2440 half a month, not previously contacted Linux, but in school contact with many do not run Linux system CPU, with Lpc1114,lpc1343,stm32,blackfin and other processor programming experience, The principle of the microprocessor and the operating mode have a certain understanding. With this little experience, as well as new learning knowledge, hands-on transplant the latest uboot, absol
