Last update october 2018

You can put the noForth image on a Launchpad and then program the chip using any serial terminal.


noForth C and V

noForth comes in two variants: However, noForth C can be used in the larger flash memories and noForth V in the smaller ones. To get an idea of the differences between C and V, see noforth words.pdf


Low Power noForths

The "Low Power" noForths are marked with a dash: noForth C-, V-, CC- and VV-.

noForth CC and VV

New january 2018
Double noForth. noForth CC and noForth VV are faster but less compact than C and V.
The priorities for noForth C and V: 1. robust and comfortable, 2. compact, 3. fast
The priorities for noForth CC and VV: 1. robust and comfortable, 2. fast, 3. compact

Egel project

egeltje The Egel project consists of about 50 elementary examples of hardware control with noForth on the MSP430. In each example you find a file with forth code, documentation and links to more information on the internet.



Three answered questions about noForth

  1. What do I need to get my program compiled in noForth?

    noForth receives the text, translates it into code and compiles that in flashrom. You need a simple communication program which is able to send text to noForth on the chip. (Teraterm for Windows, CoolTerm for OS X, e4thcom for Linux, ... )
      Baud rate 9600 - data 8 bit - parity none - stop 1 bit - flow control none -
      transmit delay: 0 ms/char, 100 ms/line
  2. Will compiled code stay in flashrom after a power off/on?

    No, unless you have sent the command FREEZE.
  3. Is it possible to erase 'frozen' code?

    Yes. Executing a MARKER or a SHIELD erases the code that is compiled after it.



Before you start:

Since noForth compiles in FlashROM, it is unavoidable that some words don't behave exactly as the standard prescribes. We tried, without restricting the programming freedom, to minimize the aberrations from the standard. This concerns:
HERE ALLOT ! C! +! MOVE (only RAM) , C, (only ROM) and CREATE
