Correct. The header is created dynamically by the TYPE statment and the data when you dim a structure. There is minimal overhead if you don't use structures

V6.01.00EXP7

PicoMiteV6.01.00EXP7.zip

MMBasic_Structures_Manual.pdf

StructTests.zip

Fixes the bugs identified yesterday and a bunch more that you hadn't found.
I'm sure you will find something else

You can now use STATIC structs in subroutines and functions - see manual

This release also standardises XMODEM and YMODEM S and S,file$ to always terminate lines with cr/lf. In addition xmodem will now pad with NULL rather than &H1A

@JanVolk, Peter,

I can confirm that with EXP7 the issue with miniFM_RC2 is fixed on RC2040 nonVGA.

@Peter:

Thanks for the explanations about the Struct internals in this post!

Edit: wrong link before - ment this one..
https://www.thebackshed.com/forum/ViewTopic.php?TID=18519&P=6#248991
Very informative! Definitely worth including in a "technical section" of the manual!

And "by the way": Pretty Code!

I also like "pretty programming"...

Thanks Peter,

The problems I mentioned recently have been fixed in the latest version V6.01.00EXP7. (minifm_RC2.bas and LIST PINS GP0 1 Boot Reserved: CONSOLE TX) (For RP2040 and RP2350).

I'm trying to play an MP3 file with an RP2350, which works fine from the command line.
Playing mp3 "b:/mp3-bestand/xxxxxxxx.mp3" doesn't work from the editor. Is this correct, or am I doing something wrong?
And then I want the next MP3 file to automatically play. (According to the manual, this should happen. There are 50 MP3 files in this folder.)
> Play MP3 "b:/mp3-bestand/xxxxxxxx.mp3" (Only one file is played.)
> Play MP3 "b:/mp3-bestand/xxxxxxxx.mp3" : play next (Only one file is played.)
Last track is playing
However, only one file is played? Is this correct, or am I doing something wrong?
I am using:
PicoMite MMBasic RP2350A V6.01.00EXP7
OPTION SD CARD GP22, GP6, GP7, GP4
OPTION AUDIO GP26, GP27', ON PWM CHANNEL 5
OPTION MODBUFF ENABLE 192
OPTION PLATFORM OLIMEX HDMI RP2350A 16MB

Kind regards,

Jan.

Quote Playing mp3 "b:/mp3-bestand/xxxxxxxx.mp3" doesn't work from the editor.

Don't understand. The editor uses all the available memory so nothing else can run at the same time.

Quote According to the manual, this should happen.

And the manual says

Quote If file$ is a directory on the B: drive the Pico will play all of the files in that
directory in turn.

i.e. specify a directory name not a filename e.g. Play MP3 "b:/mp3-bestand

The playback is limited to, I think, 20 tracks. Any more and you will have to use DIR$ and a completion interrupt on the PLAY command

Sorry, I meant from a program created with editing.

Thanks for the reply, and I'll try it tomorrow with just the folder.

Kind regards,

Jan.

Tested with just the folder, and it works. Indeed, 20 MP3 files are displayed on the screen and played one by one.

Kind regards,

Jan.

Peter,

I've done some testing, including with I2S, and the sound is much better than with the standard audio input on the Olimex module.
I used a standard Raspberry Pi Pico 2 module, soldering long pins on the underside so that the rest of the pins are also available.
A template under the PCB with all the GP numbers makes it much clearer. An added advantage is that the Audio module: PCM5102A I2S DAC can then be neatly slid between the pins on top of the Raspberry Pi Pico terminal.
I also mounted a DS3231 with EEPROM under the Olimex module, attaching the wires to the underside and securing them with 3mm and 5mm nylon bushings.

If you create "B:/mp3-file/" with EDIT PLAY MP3 and then save it to a FLASH slot, it can be started automatically with, for example, FLASH RUN n. From the > you can control the MP3 player with PLAY NEXT, PLAY PAUSE, PLAY RESUME, PLAY STOP.
