I have the same board and the same program. I bought two 1602 LCDs. One displays normally, and the other displays garbled characters. Is it because of the different LCD screens or because of the LCD d...
Hello!
My platform is DM8148, and I get the Processor List by compiling the routine and printing it:
procId =0, procName=DSP
procId =1, procName=VIDEO-M3
procId =2, procName=VPSS-M3
procId =3, procNam...
