I recently took a break from BMOW’s multi-tasking support to work on something completely different. (Actually, I have a multi-tasking demo working in the simultator, but it doesn’t work on the real hardware yet.) The “something different” was a robo-flower:…
I made a little progress this week on separating what I hope will eventually become the operating system software from everything else. Up until now, all the test programs I’ve written have essentially been the operating system, or part of…
Today I moved a few steps closer to completion of the initial hardware design. First, I verified that BMOW’s interrupt mechanism actually works. My previous experiments with the keyboard and USB employed busy loops to continuously poll for new values.…
I’ve begun looking more deeply into the “Small C” compiler that Bill mentioned. It looks very cool, yet also wildly inefficient, which is about what I expected. With some more effort, I think I could get a working C compiler…
After another round of bug fixing and the creation of a BMOW keyboard driver, the keyboard works! And it truly works this time: pressing the A key shows “a” on the LCD, and pressing SHIFT and the A key shows…
I’ve gotten a bit derailed from the task of writing the keyboard scan code handler, into the bigger issue of how device drivers like this should work in general in BMOW. That’s led me to an entirely different question of…
