RT, LPC1114 default is input, pull-up, so I did not initialize the IO, and made a judgment in the program if ((LPC_GPIO2->DATA&(1<<9)) == 0) //p2.9 low { flg = 0; } When P2.9 is Low, enter flg = 0; Th...
Does anyone have any good font extraction software?I have a few but they don't have all the functions. I want one: one with all the functions, able to set fonts, etc....
In my main program, a global variable is assigned after AD conversion. When the input value changes, it changes accordingly. It is sent to the host computer in the serial port interrupt. Why doesn't t...
I just bought a 270A development board from Broadcom, which uses the pxa270 chip. After I burned WINCE5.0 according to the instructions on it, I found that the display kept turning on and off, and it ...
