20230216b -- "Files"
Log from ROM Disassembly - AlphaSmart Pro
The gist of this unit is that you type text into a discrete 'file' and then you can edit and later transfer to a separate computer via the keyboard emulation. While whizzing through the code doing other things, various strings caught my eye, such...

Debugging
Log from 8 Bit TTA Interpreter
Debugging Need to get this project working. One problem is that the Nano does not have enough pins. So I have used a Meduino (a Mega2560 Pro Mini). Here is the schematic: Here is the PCB: The ports (P1 & P2) match the TTA8 bus. A problem with the Meduino...

Log from ROM Disassembly - AlphaSmart Pro
One thing unresolved bit of the LCD is the R/~W line. I had largely assumed that the display was write only in this product, but I was quite wrong as reading is needed at least to poll the 'busy' bit in the status register. I had found the...

Micro-coded controller deep-dive
Log from Custom circuit testing using Intel HEX files
In this project, instead of using a standard embedded processor and programming it to execute 3 tasks at hand (parsing HEX character stream, generating HEX character stream, and writing character stream to video RAM driving VGA), I created 3 independent...

New and Improved Version
Log from Fitting a Quadratic Bezier Curve to Point Data
Code RebuildI rebuilt the code for a different staing point. Instead of: B(t)=(1-t)^2*B0+2*t*(1-t)*B1+t^2*B2I refacted the equation to: B(t)=(B0-2*B1+B2)*t^2+2*(B1-B0)*t+B0The error squared for each "t" is: e^2=((Bx0-2*Bx1+Bx2)*t^2+2*(Bx1-Bx0)*t+Bx0-Xi)^2 ...

We recommend studying nonequilibrium statistical mechanics to really thoroughly understand the experiments you can perform with the bipolar membrane devices. The best course I have found on this topic is by Prof. V. Balakrishnan on Youtube.Here you can...
