• Running on a breaboard

  Lars Brinkhoff • 11/07/2019 at 12:26 • 0 comments

  Forth code running on an ATmega328P device blinking a few LEDs.  A simple ISP programmer is attached for in circuit programming.

• On hold

  There haven't been much progress lately.  The basics are there, but more features and polish are needed.

  I hvae been busy working with the PDP-10 Incompatible Timesharing System:

• User Manual

  There's now a very brief user manual:

• Users?!?

  Lars Brinkhoff • 11/30/2017 at 06:16 • 0 comments

  I've had two people inquiring about using the cross compiler within a week.  I guess it's about time I made a proper user interface, and start writing a manual.

• Tested on hardware

  Lars Brinkhoff • 10/26/2017 at 07:25 • 0 comments

  Almost done testing on hardware.  These devices can display a blinking LED:
  

  • ATtiny13A / Cheepit Sparrow
  • ATtiny85 / Adafrut Trinket
  • Cortex-M0+ STM32L011 / STM Nucleo-32
  • MSP430F2012, MSP430G2452, MSP430G2553 / TI Launchpad
  • PIC16F1619 / Microchip Curiosity
  • STM8S103F3P6 / Noname breakout board

  I haven't been able to program my SiLabs 8051 using a ToolStick board.  If someone can suggest another 8051 which is easy to use, I'm all ears.
  

• Thumb/Cortex-M

  Lars Brinkhoff • 09/25/2017 at 19:36 • 0 comments

  Added support for Cortex-M devices using the Thumb instruction set.
  

• Testing on hardware

  Lars Brinkhoff • 09/13/2017 at 17:48 • 2 comments

  The compiler is tested on simulators for all targets, but I'd like to be able to test on real hardware.  This is the status so far:

  • 8051: no hardware.
  • AVR: tested on ATtiny85, soon ATtiny13.
  • MSP430: I have asked Ken Boak for a ChipStick board.
  • PIC: no hardware.
  • STM8: @Thomas has offered to send a board.

  I'd appreciate advice on which hardware to use for testing.  It should be easy to program, and there should be a LED or something to indicate a succesful test.
  

• PDP-8

  Done with 8051, almost done with PDP-8.

• 8051

  Lars Brinkhoff • 09/05/2017 at 20:30 • 0 comments

  Started with 8051.
  

• 6502

  Lars Brinkhoff • 09/02/2017 at 19:30 • 0 comments

  Added 6502, more for fun than actual utility.
