Put the noForth image on a processor board and then program the chip using any serial terminal.

noForth m is for MSP430, runs in ROM, 1 cell is 16 bits.
noForth r is for RISC-V, runs in ROM, 1 cell is 32 bits.
noForth t is for RP2040, runs in RAM, 1 cell is 32 bits.

When we use the word ROM it may be FROM, FRAM, Flash ROM or Flash RAM.


  Until now we have the following noForth variants:

    m  mv  mc  mcv    r  rv  rc  rcv    t tv

    m = for MSP430
    r = for RISC-V
    t = for RP2040 (thumb2)

    c = compact
    v = with vocabularies

  "Low Power" noForths for MSP430 are marked with a dash:

    m-  mv-  mc-  mcv- 

The priorities for noForth are: 1. robust and comfortable, 2. fast, 3. compact.
For the compact variants: 1. robust and comfortable, 2. compact, 3. fast.

In the list below you find the noForth images (binaries). It may be necessary to adapt the CONFIG list (settings for Baud rate, Clock speed, etc.). Follow the instructions in the README file. Advice: always use the latest versions.
Once noForth is in the chip you have to include the file <noforth r tools.f> or <noforth m tools.f> for .S WORDS MANY DMP and SEE.

How to get noForth in the MSP430

Put the noForth image in the MSP430 with the 'UniFlash' program (by Texas Instruments).
See howto use uniflash
Uniflash will not function with the MSP430F149. See howto f149
With the FET-interface on the MSP-EXPFR2355 all MSP430 chips (with the exception of the 100-series) can be programmed. See msp-exp430fr2355 as programmer

Four 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, ... )

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.

4. Is it possible to change clock speed, Baud rate, serial port, port and pin for the APP button from within noForth?

   Yes, see the documentation in:
   configs msp430.zip
   configs gd32vf.html (for RISC-V)
   configs-rp2040-noforth-t.zip

Before you start

• When noForth compiles in FlashROM (MSP430 and RISC-V), 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.
  See readme-1 and readme-2 below. This concerns the words:
  HERE ALLOT ! C! +! MOVE (only RAM)
  , C, (only ROM)
  CREATE
• noForth skips characters greater than hex 7E in the input stream.
• WORD does not exist in noForth. Use BL-WORD instead of BL WORD .

  Conflicting names

• NEXT is state-smart

  Compiling: the NEXT of FOR-NEXT.
  Executing: the assembler-NEXT of the inner interpreter.

• Only for MSP430 without vocabularies: # is state-smart

  Compiling: the forth-# for number printing.
  Executing: the assembler-# that denotes a literal.

• MSP430 only: AND and XOR (forth vs. assembly)

  In noForth assembler the msp430-AND is BIA .
  In noForth assembler the msp430-XOR is BIX .
  This is in harmony with the existing msp430 commands BIC and BIS.

  How to make a turnkey system

  ' <my-application>   TO APP   FREEZE
  
  Put the application token in the value APP and type FREEZE . The execution of the APP vector can be bypassed with a switch.
