Dear experts, I use WAVE IDE or keil, and I now have a file with the extension OBJ (I don't have the original file), which defines some functions. I want to call the functions in this file in another ...
Since the light characteristics of LEDs are usually described as a function of current rather than a function of voltage, the relationship curve between luminous flux (φV) and IF is good. Therefore, u...
I use 430 5438A as the CPU and use its 4 serial ports to control different instruments. Is it because the serial port interrupt priorities are the same? So once it is generated, one action is executed...
