  • FAT32 File Format

  • When you search google for FAT file format you get tons of pages on formatting disks. It's harder to pull out the detailed format of the SD card. Wikipedia to the rescue (Design of the FAT file system). A less technical FAT32 Wikipedia page is File...
  • All Your ISA Belong to Me!

  • Before I began the layout of the DDL4-CPU, I came up with an initial Instruction Set Architecture (ISA) for the design. It went through several revisions as I was designing the boards and refined the components. Here at the last minute as I am...

  • ACPI is working now

  • At last, I found a bit in EC RAM that is used to enable EC ACPI, so ACPI is working now. I copied the ASL code from vendor DSDT, and now battery, AC, and lid status change can be detected by OS now.https://review.coreboot.org/#/c/19072/
  • Smooth operator

  • Put the capacitive reading code to use.Started with code from here: https://forum.pjrc.com/threads/31797-Teensy-FSR-based-MIDI-controllerAdded a calibration stage where it detects the base capacitance at startup.Modified it to use this library for smoothing...
  • Project Resumption

  • I'm going to eb hopefully getting my teeth back into this project after a while on the shelf.One thing I was dubious on was how to handle the shutting down of the Pi safely when the car is switched off without causing corruption in the filesystem.One...
  • Rev1 Voltage Test

  • I did another test with the rev1 prototype, this time only measuring voltage, and bringing it all the way to the maximum voltage of 60V. Again I am doing calibration and comparison to my Fluke 101 Multimeter. This has a problem as the Fluke 101 does...
  • Remapping the Keyboard

  • Remapping the KeyboardGiven most of the work is done with the "basic shift logic" how hard could it be?The basic shift logic:Well much harder than expected, here is the schematic:Now many will recognise this as a PLA (Programmable Logic Array).Designing...
  • More Peripherals and some tablet bytes.

  • The amazon fairy dropped off a "NES Classic Controller" and a "Classic Pro"The classic pro comes up as a classic controller, The only difference is the analog R and L on the one I have are buttons and just return the max value when pushed. Although this...
  • 20230221b -- File Inserting

  • Intrigued by the various file-related pointers seen in deleteThisFile_EB9B, I remember that the keyboard scan routine had a final case where the bulk of the keystrokes (the printable ones) are handled, and there was a scan code to ASCII routine before...
  • Could this work?

  • I recovered the project file from my drive and made some changes to it. The question is, which wire goes where? I won't know for sure until the dummy plug arrives, but the AUX line is definitely used for this purpose. I even created an EDID data for...
  • Z80 (CP/M) Writing to SD Card

  • Digging into SD card writes means shifting gears from the Boot BIOS source code since the Boot BIOS code only does reads. The CP/M BIOS code (CBIOS128.LST) which does the reads/writes after booting. Here's the BIOS code for writes to the SD Card: 0754...
