So, if you have a Pi 3 please could you test serial output for me. First try the release as delivered (WAVETIME=1.0). If that doesn't work (i.e. you get garbled output) try 1.128.

If that also doesn't work and you have access to an oscilloscope or logic analyser please try the following:

open "COM1:1000" as #1
do
print #1,"U";
loop

Please also let me know the exact version of the Pi 3 you are testing on - mine is the Pi 3 Model B V1.2 and MM.DEVICE$ reports A02082

Thanks for any and all help on this one.

Pi 3 B V1.2 and MM.DEVICE$ reports A02082 - same as yours.
With the default settings ( no options set), I measure 100mS bit length.

Playing with a USB TTL adapter

Quote ' serial test program
System "stty -F /dev/ttyUSB0 38400"
OPEN "/dev/ttyUSB0" FOR random AS #5 ' open the serial port
PRINT #5, "HELLO!!! Is anyone out there?"
DO ' prefered way to recieve serial data which might not be there!
k$ = INPUT$(1,#5)
IF k$="" THEN
nodata=nodata+1
ELSE
result$=result$+k$
PRINT ASC(k$),result$
nodata=0
ENDIF
PAUSE 20
LOOP UNTIL k$=CHR$(10)OR nodata=50 ' 50*20ms = 1 second timeout
DO
PRINT #5, "U";
LOOP

CLOSE #5

The SYSTEM command can be used to change the baud rate of the attached adapter.
The adapter defaulted to 9600 baud and was successfully changed.
I haven't tried any other options with the stty command. Changing baud rate should be enough for most users. The stty settings seem to be 'sticky' but I would put them in my program 'just in case'

I tried to run SYSTEM "dmesg | grep tty" from the mmbasic prompt but was kicked out of mmbasic with an error.

Edit : The previous post should read 1mS bit length, not 100mS. We are not THAT slow down under.

Quote Settings in .options are not stored in ASCII format, correct?

Correct, they are in normal binary representation

Quote So, when I use the internal editor and store the Programm it is lost when I exit mmbasic?

"Save" in the editor moves the program from the edit buffer and "saves" it in normal RAM ready for execution. Unlike the Micromite, the Raspberry Pi always has a SD card available so, to save for next time, it is just a matter of saving to disk once you have exited the editor.

Thanks Jim, your Pi obviously works perfectly, I somehow need to track down the difference in my setup. Do you have an HDMI monitor connected?

Raspbian Jessie Lite without any keyboard or monitor.
I only ever connect with Teraterm (or WinSCP).

@ Tassy Jim

Precisely which PiMiteBasic download are you using ?
I haven't kept up, and the latest ones give me screen garbage :(
I want to try what you did but with MIDI baudrate .

Later releases use an additional library

Try installing

[code]sudo apt-get install libncurses5-dev[/code]

This change was introduced on page 14 of the thread to support the EDIT command in full colour

If I use it now takes me nowhere (back @ prompt) ???

You definitely need sudo now.

I've had this issue with going to the @ prompt and it is probably that .options has been corrupted with the failed starts

So:
make sure you have version 64 of pigpio installed (2nd post page 19)
delete mmbasic
delete .options
reboot
recopy mmbasic
run with sudo

If you change versions ALWAYS delete .options before running any new versionEdited by matherp 2017-06-23

Same place as mmbasic. It is a hidden file just go

rm .options

and Linux will prompt for confirmation

O.K........

Worked once but wouldn't work again
I hadn't rebooted
When I tried, RPi wouldn't boot
(someways contaminated SD)
Lucky I had spare SD

Request: way to break out of running loop .....
Like Ctrl-Break in GW-Basic

I seemed to be writing to synth,
but no sound ????
Nice ...... I will dance at your wedding

ctrl-C ?

Then use ctrl-Z to exit mmbasic

Never just close the terminal session without exiting mmbasic or the program will be left running and you will have to "kill" the mmbasic processes (2) or reboot before you can run it again

Right ..... I've forgotten my MM stuff

All between each session ?

No
only when you install a new version.

Always start mmbasic with sudo ./mmbasic and always exit mmbasic with ^Z

If mmbasic has crashed, you might have problems restarting mmbasic in which case restarting the Pi will help (just like with Windows programs)

With the more recent versions on mmbasic, I get fewer crashes and mmbasic seems to be better at recovering.

System "stty -F /dev/ttyUSB0 31250"
OPEN "/dev/ttyUSB0" FOR random AS #5 ' open the serial port
PRINT #5, "HELLO!!! Is anyone out there?"

Thank You Jim ..... While you're handy
(you answered this long ago but I don't remember
and can't find with search)

What do I do with the PRINT to simply send integer bytes ?
Maybe Matherp will do a WRITEBYTE or PRINTBYTE ?

hello Peter, hello at all,

good news,.. my code for a PiCromite Remote Control is running an working - Once to test the possibilities

using option wavetime 1.3 to tweak the pulselenghts
it now working together with all my "Smartwares" Unites and a cheap 12V Ledstripe Controller, see my old smart home thread too

Hi Peter

I have the same version PI3 as you A22082
Serial out is garbled but if i use OPTION WAVETIME 1.128 the program in memory gets erased. If i reload the program and run it it gets erased. To resolve the issue i deleted the options file reboot then it works. Readding the OPTION WAVETIME 1.128 produces the same wierdness

Regards
Jman
