Yes, it turned out I was on the second flash of AmForth (on a separate 
chip), with "Evalue" being

defined on the first chip... (something went wrong and I had to flash 
AmForth again).

I have done that now, and it works now! That was probably

the crucial step (though I don't understand why(?)).


I could also define "tk.custom" and set it up with "    ' tk.custom is 
turnkey    ", putting

my main init and infinite control loop in there, all in word 
"mainApplication". After a power

cycle, the control loop ran immediately, as it should.


The control loop can be terminated by removing a jumper that pulls a 
digital

input low (pulled up externally with 10 kΩ). The jumper is located on

my custom Arduino shield.


Also, connecting the Arduino Uno to USB while in the control loop 
(mainApplication) does not

reset the I/O and does not disrupt the operation (unlike normally, 
where, even if powered from

a 9 V battery source, connecting will reset - though I cannot rule out 
power glitches). When the

jumper is removed the normal interactive stuff is available.


Everything works as it should!!


For this try, I had to flash AmForth a third time (due to another 
incident, an unfortunate paste error...)

and used the opportunity to see if I could repeat it. This was also to 
automate as much as

possible (.BAT script calling AVRDUDE for the flashing, launching PuTTY 
with the profile

for this (38400 baud, etc.), and running several AutoIt scripts for the

source pasting). There were a few corrections.


The fourth time, with a few more changes for automation (mostly focus 
changes in Windows), should

reduce it to moving the chip from the ISP programmer to the Arduino and 
a single press of Enter

when it has been moved. But this is not needed for this first 
deployment, only for subsequent

versions (if there will ever be more). With direct ICSP, just starting 
the script should be enough.



     : tk.custom

         \ Call the previous turnkey action.
         tk.amforth execute


         \ Now something specific e.g.

         \ I_O-setup

         mainApplication
     ;
