#181755 - Found the problem !!! Responding to: ???'s previous message |
Dear all,
I'm sorry for all the trouble ... The problem was that I placed VPP / EA' to a GND ... While I am not using external memory ... So my MCU keeps on trying to find a program outside of the MCU ... Switch it back to VCC then .... everything works !!! Silly me, I just extracted my design from old project without re-analyzing the design. Mr. Michael. Since my initial program was only to test my design, so I did not put any initialization command at all. When it is fully assembled (I'm building a Serial Display which received stream of data from PLC), then I will have to put avery code in order. Once again thank you all very much. Best regards, Didik Chandra |
