VM(Virtual Machine) on Morikawa as one of the Morikawa Apps worked successfully. Now we can upload various codes to INVADER from ground station and execute them on orbit. SOUECE CODE DOCUMENT ASSEMBLER We have tested the following 2 programs and executed correctly on orbit. 1. Write CURRENT_SOLAR to TEXT_Y three times and transmit “invader” in Morse —- Assembly SETC, FUNC, getTelemetryCurrent SETC, ARG0, 2 CALL SET, HCUR, 0 MOV, HEAP, RETV SET, HCUR, 4 MOV, HEAP, RETV SET, HCUR, 8 MOV, HEAP, RETV CLR, HCUR SETC, ARG0, 1 SETC, ARG1, 12 SETC, FUNC, setText CALL TXT, 7, invader SETI, ARG0, 1047 SETC, ARG1, 7 SETC, FUNC, playMorse CALL SETI, ARG2, 1200 WAIT, ARG2 END —- Hex Dump by iva 2109 0301 1d03 0502 0802 0300 2000 0506 0402 0203 04c0 0800 0880 080d 0503 0305 0103 060c 0301 2308 1f07 2013 1869 6e76 6164 6572 0405 1704 0306 0703 0149 0804 07b0 041e 0700 —- Result 2.
