Android MCU Prototype Board Simulator (free)
The MCU simulator for Android OS runs Assembly Language code similar to the 68705 MCU on a simulated on-screen prototype board. Great for embedded applications hobbyists, students, teachers or anyone who likes to experiment with Micro-controller CPUs and electronic prototype boards. It's fun for learning Assembly language as well!
AndMCU simulates both software and hardware. As on a real prototype board, your ASM code must configure the MCU I/O ports to control the hardware connected to it, such as lighting up segments on the digits, or reading keystrokes from the keypad or dip-switches.
You can use the simple built-in text editor or any Android text editor of your choice to write your assembly code and then load it into AndMCU to run it.
The built-in assembler has many useful directives such as step-by-step trace mode, break-points, dumping memory contents to an HTML file, adjusting the CPU speed and auto-running the loaded code. It supports the following opcodes (subset of the 68705 MCU instruction set):
NOP,CLC,CLI,SEC,SEI,STOP,SWI,TAX,TXA,LDA,LDX,STA,STX, ADD,ADC,CLR,CLRA,CLRX,DEC,DECA,DECX,INC,INCA,INCX,SUB,SBC,
AND,CMP,COM,COMA,COMX,CPX,EOR,LSL,LSLA,LSLX,LSR,LSRA,LSRX,
NEG,NEGA,ORA,ROL,ROLA,ROR,RORA,TST,TSTA,BRA,BSR,BCC,BCS,
BEQ,BNE,BHI,BLO,BLS,JMP,JSR,RTS,RTI,BCLR,BSET.
The AndMCU board simulates the following hardware components:
1) 8-Bit CPU with 3x 8-bit bi-directional ports.
2) 6 Digits display
3) 16-character LCD display
4) 2x 8-bit DIP Switches
5) 2x8 LED Bargraph displays
6) 12-key keypad
7) 1 piezo buzzer
8) External, Timer and Software Interrupts
9) 1 analog input (light sensor).
* Works on screen resolutions up to 1080 x 1920 (Full-HD).
(This is not a fast CPU emulator - it's a simulator for educational purposes. See documentation on AndMCU's website for more details.)
