On this page I release several smaller tools to help programming the VM. Additionally you can find here small test programs for the VM. For the programs and tools found here there is not much documentation, even less than for my bigger projects. If you have problems, ask me.
Here you can find two tools written in perl to convert PPM P3 (ASCII mode) files into source code usable as icons and full-screen bitmaps. Older versions have been released earlier in the egroups file area.
The VM has a clock mode were it uses a RC oscillator as system clock at 600 KHz. RC oscillators are not crystal stabilized and have big tolerances, +100%, -50% according to a posting on vmu-dev. So I wanted to know how fast my VM really is and how stable the RC clock is. So I wrote a program for that, here it is. It displays the current RC clock speed in KHz after 2 minutes. Obviously the programs runs in RC clock mode in this 2 minutes, so it drains the batteries really fast. Start again by pressing A. For softvms version 1.8 divide the values by 6.
To get more accurate results I have increased the measure time to 2 minutes. Additionally I have removed bugs in the round to nearest KHz code.
