Re: [Amforth] error uploading ports-standard.frt

[<ho...@tj...>]

Hi Jochen and welcome.

AmForth is complaining when you upload ports-standard.frt because it 
cannot find the word synonym. This is not a built-in word and so needs 
to be uploaded before trying to upload ports-standard.frt
synonym can be found in this file

./common/lib/forth2012/tools/synonym.frt

To use the ADC will require some additional Forth words. Below is a link 
in the AmForth documentation (if you have not already found it)

https://amforth.sourceforge.net/TG/recipes/Arduino-Analog.html?highlight=adc

The ADC unit on the ATmega328P, the mcu which powers the UNO, does have 
more to offer than is made available in the above words. Whether that is 
important to you depends upon what you want to do and your appetite for 
reading the datasheet and modifying this set of Forth words.

tools/amforth-shell.py --help

amforth-shell.py can use the environment variable AMFORTH_LIB which 
helps with this.

Let us know how you get on.

Kind regards,
Tristan
