arduino nano and bablefish

Post by Huskeyw » 28 Mar 2019, 00:30

so I have an arduino nano connected to the DB9, and its running babelfish, I get the serial output, that shows the gigtron is OK.. I tell it to load a build in program as a test and it says it loads and executes but it does not..

reset command and keyboard input are not working as well..

this is V2 bios

Code: Select all

 Gigatron OK
Cmd?
:Echo on
:Gigatron OK
Cmd?
H
:Commands are
: V        Show configuration
: H        Show this help
: R        Reset Gigatron
: L        Start Loader
: M        Show key mapping or menu in Loader screen
: P[<n>]   Transfer object file from PROGMEM slot <n> [1..12]
: U        Transfer object file from USB
: .<text>  Send text line as ASCII key strokes
: C        Toggle echo mode (default off)
: T        Enter terminal mode
: W/A/S/D  Up/left/down/right arrow
: Z/X      A/B button
: Q/E      Select/start button
:Gigatron OK
Cmd?
A
:Gigatron OK
Cmd?
D
:Gigatron OK
Cmd?

:Gigatron OK
Cmd?
M
:Gigatron OK

M
:Gigatron OK
Cmd?
P1
:Loading 11 bytes at $7F00
:Executing from $7F00
:Gigatron OK
Cmd? 

not sure why.. if its says its ok is it not talking to the board?

just takes asking the question to see where you mess up.. was looking at the mini pinout.. I guess the latch and sync is what the program is looking for, the data pin was wrong..

Indeed,

Code: Select all

Gigatron OK
means there are two sync signals coming from the Gigatron with roughly the expected duty cycles.
