Can one use Movx instruction in EdSim51?

The 2-pass assembler with the EdSim51 Simulator is not a full-blown assembler. All of the 8051 instructions are implemented, except for MOVX instructions, as the simulator does not handle external memory.

Can you write C programs in edsim51 simulator?

It was developed and compiled using the Keil uVision3 IDE. If you wish to write your own C programs for the 8051, get the free evaluation version of uVision3. The EdSim51 simulator can only parse assembly programs. It cannot compile C programs, therefore do not try to copy and paste the program below into EdSim51.

Where do I find elapsed time in edsim51?

When a program is running, the amount of elapsed time (as far as the 8051 is aware) is displayed in the field above the source code. The user can set the number of instructions executed between updates to the simulator GUI by selecting a value from the Update Freq. menu. Certain update frequencies suit some programs better than others.

Which is the target board class in edsim51sh?

It consists of one LED and one switch connected to the 8051. TargetBoard is an abstract class that should be extended by the target board developer. Documentation for this class can be accessed from the above link. The example projects are provided so that developers can see how peripherals are written for EdSim51SH.

Where does the external 0 ISR go in edsim51?

The external 0 ISR ; on P2 and passes it to the DAC on P1. ; same as the ADC input voltage. ; next timer 0 interrupt). ; the ADC is enabled (not the comparator). When running this program with Update Freq. set to 1, the student will observe the time delay between a change in the ADC input voltage appearing on the scope.
