In uv2 environment, I am running a hardware simulator. Why those two busters are keeping happening? 1. P0 port can not output data correctly, it changes randomly and totally out of my control. 2. Why this message is keeping showing up "Can not access to target while executing", while I still can debug the program? Thank you.
What is this hardware simulator?
This hardware simulator is an 8051 family development kit. It has its own development platform, although it can be developed in uv2 environment. Right now I am simulating AT89C52 MCU. Thank you.
So, I guess you are really running the Monitor-51 on your target hardware. Remember that P0 is the data/address bus of an standard 8051. So you are not simulating, but you are executing on real hardware. However the hardware includes a control software that runs while you view variable values.
