I would like to ask you all: I passed a virtual address of NORFLASH to the third parameter of the last function OEMLaunch of my EBOOT, and finally I can jump to Startup.s in OAL (you can see it by tur...
In Keil C: float f=4.215; printf("%6.2f", f); Output: 4.21 //There are two spaces in front. How can I printf to output 004.21, that is, fill it with 0 instead of spaces?...
My program calls the API function TouchCalibrate() to let the user calibrate the touch screen. After calibration, the program writes the calibration value CalibrationData under the registry HKEY_LOCAL...
The boost circuit is 12V to 48V to power the POE module. The camera is powered and communicated through the POE port. When the load is 8W, the voltage drops from 48V to 40V (the camera works normally)...
Question: Putting the code in different places has different effects! Please give me some advice.
