|Alpha : Visual Tour Developer Mode Walkthrough|
Lets click Program | Blank Check and see if our device is blank. It is not.
NOTE: If you have just used a device programmer to program BLPro_2550.hex into (the high part of) the PIC processor's Flash program memory, you may be surprised that BLPro.exe tells you that your device is not blank: you would expect the target area of program memory to be blank at this point.
This is almost true, but the bottom 3 words of program memory at this point contain a branch to the bootloader up in high memory, so our Blank check **fails**: our device is not quite blank, and our device will need to be erased before re-programming.
