I'll add it to the (previously empty) bug list

@Peter,

I am sorry to report a bug in 6.00.02 release.
This is tested on PWM audio on 6.00.02 on the VGA design 2 platform, but could very well be transparent over multiple platforms.

In my effort to display Lissajous graph, I tried this:

PLAY SOUND 1,L,S,1000,25
PLAY SOUND 2,R,S,1001,25
DO : LOOP

The left channel shows a sine wave centered around 1.65V, frequency 1kHz.
The right channel does not show a sine wave centered around 1.65V, it switches to 3.3V dc.

Even when I comment out the L channel, the right channel outputs DC.

Volhout

don't the x,y have to be different phase?

No - its just a simple typo in the right channel code

duh. I was told on this forum that to get Lissajous you needed 2 sines at opposite phase. wanted to make a component tester... not really I got one measures everything.

When frequenties of the 2 are different, there Will be moments where phase is opposite.
And moments when not. So you get a rotating elypsoid when viewer in xy mode.

Apparently PLAY SOUND has been forgotten in testing for a long time. I know that Game*Mite uses play sound (the entertainer), but since it mixes L and R this was not detected (you hear a click, and slightly less loud sound).

5.08.00 : PLAY SOUND works
5.09.00 : PLAY SOUND, all waveforms work except sine wave. Sine wave has amplitude 0.
6.00.01 : behaves identical to 6.00.02
6.00.02 : R channel gives DC, no modulation, on sine wave. L channel works fine.

As the Germans would say:
"Vergangen, Vergessen, Vorueber.... Vergangen, Vergessen, Vorbei".

For this Lissajous demo. I'll revert back to 5.08.00 (unless there is a quick fix for 6.00.02 .. but 5.08.00 will do fine for this application).

While you are waiting will this be adequate?

PLAY TONE 1000,1001

This does give two frequencies in 6.00.02, though if you need to vary the amplitude a pot on or two would be needed.

Hi Phil,

Thanks for the suggestion, but in this particular case I need to play sound because I can mix in other signals as well.

The first time after booting or cpu restart, PLAY MP3 fails, but only the very first call. From then on it works:

Hi
I've not updated for 2 years or so and now I'm trying to understand all the new hardware and updates.
Looks like a lot of work, well done.

I want to connect an e-ink display but in the section for displays I cannot find any listed. There's SSD1306 OLED but not e-ink.

All help appreciated. Thanks

MATH WINDOW in(), minout, maxout, out() [,minin, maxin] Manual page 128

Not sure if this a bug or the manual needs an extra note.
minin and maxin need to be floats. Integers give less than useful results.

Using the example in the manual:-

I want to connect an e-ink display but in the section for displays I cannot find any listed.

Every e-ink display seems to have a different controller chip and the ones I originally supported have been superseded and are no longer available. Accordingly, I have removed support for e-ink displays. You can use a user-written driver to support them but you are on your own to decode the vagaries of how they work - Sorry.

Thanks for the update.
As there are two commands REFRESH and AUTOREFRESH in the latest manual I was hoping for a different outcome.
Many thanks for the fast reply.

Changing fc and bc doesn't work with V6.00.02
I get one comma too many, which causes an error message with the same colors after adjustment.

Works for me



First comma just indicates that the font is default

Thank you Peter.
I had not tried these color inputs yet. Names and numbers. Something for the manual possible?

Greetings,

Jan.

Peter,

I did this. The final result, for the new color input, is quite a challenge, along with the manual.
Is it not entirely accurate, or is the manual incorrect?
It does work.

I use this as a scrolling settings list with an Arduino serial connection(3V3), which works correctly.
The Arduino has a blue 4x20 I2C LCD, hence the colors.
