Programming a Finalgrom99

[Mehridian Sanders]

Hello all,

 

So does anyone have experience programming a FG99? If so what did you use? My brain hurts from the weekend and I am missing neural connections somewhere. Did you use a RPI to program it? bout to try this out on my 3B+.

Can't seem to find the pinout on the FinalGrom99 spi connector.

3.3v O O ?

Sorry Mixed up my connections

I have read over the github for this : https://github.com/endlos99/finalgrom99

I cannot figure out what the other pins are. If you have a direction you can point me in, no matter if it makes me look stupid or naive, I don't care. If I can pin this out I should have a working FG99 soon. I would rather look foolish and have a working FG99, than no FG99. (money was a factor in my decision to make my own)

 

Thank you kindly in advance.

Eureka!? Maybe

Due to the time of year and illness, my projects have slowed down. In the meantime, would any be interested, should it succeed, in a Layman instructable? Here or on Instructables? thoughts?

Instructables are always useful. . .sometimes their value doesn't become obvious until months or even years down the road, but they almost always end up helping people.

So my co-worker was chatting with me today, about my Finalgrom99 project, about 20 mins into shift. The conversation swung round to Python coding, and he says, "Yeah, Python can be tricky. Especially since 3.* and 2.* are incompatible"

 

.... *internal facepalm*

 

So when I get home I will be trying to run the 2.7 compiler instead of the 3.5 I have been trying to use.... 

 

.... *rolls eyes, shakes head, sulkily walks away*

 

Well at least that lil bit of unpleasantness is over with.

 

Please feel free to laugh. I did. ?

Update:
Finally got round to making more time to program the FG99.
CHECKLIST :
- I got a python version of 2.*
- I redownloaded the FG master and Xdt suite.
- Fresh Buster install of Raspian on the 3B+
- Installed xdt suite, Avrdude and TI Logo background (for luck!).

Ran the make.py script in terminal.
Still no love ... cant find the files...

Let The Debugging Begin!!

Should I move this over to the development forum as I am running this on Linux? and debugging code ?

If so please move this thread.

somehow keep running into the same error :

OSError: [Errno 2] No such file or directory

i did make sure to add the PATH

sys.path.append('/home/pi/finalgrom/xdt99')

all of the xdt suite files are there

I am not really versed/instructed in Python... I am googling most of my questions. So if you know something basic to python that would be beginners noob level, don't hesitate to interject it. ? the more I know!

 

I have made a Stackoverflow account which should also be helpful.

 

Thanks in advance.
