Mixtel90 said I've found that with a lot of modern LEDs you only need a couple of mA, especially for indoor use. You can sometimes manage with less than that.

I ran a PICAXE for 11 years off of the same 3 AA batteries, blinking an LED with a 22K resistor every 7 seconds. You had to shade the LED in your hands to be able to see it, but there it was--heartbeat on 4V5/22000 -> .2mA.

It was visible (barely, after 11 years, when quite dark) down to 1.8V, so 1.8/22000 -> .08mA.

Here's a picture of a Pico version of my MMBASIC automatic nightlight. A Waveshare DS3231 RTC board is under the Pico. The relay board is from Evil Mad Scientist.

Updates to MMBasic to bring in-line with Geoff's latest release

TEMPR fixed

Speed improvements to SDcard access. Note if the selected pins are valid for spi0 or spi1 the firmware will automatically use the H/W SPI which will block it for other uses, this is in preparation for LCD displays and touch. NB using the SDCARD will always be comparatively slow. The FatFS code is large and has many moving parts which is going to kill the instruction caching. The TA program read test is particularly bad as it repeatedly opens and closes a file rather than just reading

FFT fixed

Edit colours changed

NOTE TO CDEAGLE

I loaded npoe using autosave C and it loaded fine. I had to change a variable name "inc" in a couple of places to "iinc" and it seems to be running

Thanks Peter. I have not used the AUTOSAVE Crunch command until now.

Thanks also for the PicoMite version of MMBASIC.

@ matherp - Way back near the start of this thread, you had just about given up on this port, cos of issues with the memory slots. Then you found a solution, and the port continues to this point.

I am very curious as to what you needed to change/do to fix the problem with the flash slots that was JUST ABOUT causing you to throw in the towel on this port. That was never elaborated on other then to say that you found a way around it.

I would love to know what you needed to do to get things to work - just to satisfy my curiosity more then anything else, but I expect other members here are also wondering what you did/had to do to get the port back on track.

Welcome back, BTW.

a26: something strange with PWM.

When I run a program that uses pwm. stop it , and re-run it I get:

[18] Setpin 1,pwm0a
Error : Pin 1 is in use.

Even with switching the PWM off prior to re-defining, the same error

PWM 0, off
Setpin 1,pwm0a

I get this error.

Quote a26: something strange with PWM.

Can't replicate - please post a program that demonstrates the issue

SetPin 1,pwm0a
PWM 0,1000,50
Pause 10000

The above works fine whether I interrupt with Ctrl-C or run to completion

Hi Peter,

'dual Servo sweep

'defines
FREQ=50 'Hz
PERIOD=1E6/FREQ 'us
PWmin=800 'us
PWmax=2200 'us
DCmin=100*PWmin/PERIOD '%
DCmax=100*PWmax/PERIOD '%
DCrange=DCmax-DCmin
ANmin=-90 'degrees
ANmax=+90 'degrees
ANrange=ANmax-ANmin

'IO setup
'PWM 0,off
SetPin 1,pwm0a
SetPin 2,pwm0b

'Sweep servo
Do
For angle = ANmin To ANmax Step 1
DC = DCmin + ((angle-ANmin)/ANrange)*DCrange
PWM 0,FREQ,DC,DC
Pause 20
Print angle
Next angle
For angle = ANmax To ANmin Step -1
DC = DCmin + ((angle-ANmin)/ANrange)*DCrange
PWM 0,FREQ,DC,DC
Pause 20
Print angle
Next angle
Loop
End

To be honest, this is a program residing in flash from an earlier release (I think a22). I noticed this program "looked" good (no token changes). But has this error message.
I erased the memory, and via autosave loaded it back in again. And the problem is consistent. After initial run you can only get it to run again after a power cycle.

EDIT: SOLVED

After OPTION RESET and VAR CLEAR it works. My oops.... Sorry

I've updated to a26 and the SDcard has stopped working again, any suggestions as to what needs to be kicked:

> option list
OPTION CPUSPEED (KHz) 250000
OPTION SDCARD GP15
OPTION SYSTEM SPI GP10,GP11,GP12
> files
Error : A hard error occurred in the low level disk I/O layer
> Warning: SDcard Removed

I'm using the SDcard on the Cytron Maker Pi Pico (rev 1.2) board.

Thanks in advance,

Tom

Hi Peter

Attached in a zipped file of a crunched version of NPOE. It runs on my Pico without any problems. After crunching, the source file is about half size. There is a bit of time before new screen displays appear.

How is this crunch being performed?

@lizby

The NPOE MMBASIC source code is opened in an editor (Geany for example). The entire file is selected and copied within the editor. At the Teraterm command line, autosave c [Enter] is typed. The copied file is then pasted into the Teraterm command window.

The NPOE program can then be run and saved to disk or sdcard in crunched format.

Also learned about geany--another multi-document text editor. I've installed it and am about to start using it for the 4th multi-document project I'm working on--alongside NotePad++, EditPad Lite, PSPad, NoteTab Light, fbIDE, . . ..

Thanks for that, too.

hi cdeagle,

About NPOE and crunching....
If I look at this, another 1k can be shaved off in crunch mode.

MMBasic does not need all this space (read: these spaces).

Regards,

Volhout

Joining the club. Got my Pico. Loaded drivers on Win7 using Zadig. Alpha 26 is running fine.

By the way, two devices appeared in Win7 Device Manager after connecting Pico.
First device - Board CDC - it became a com port after installing drivers.
Second device - Reset - what is this device for?

Using a26
I'd setup OPTION AUTORUN 10 to load & run a program that set DATE$ and TIME$ from a DS3231 on i2c then executed NEW to wipe the program from memory. I'm pretty sure that DATE$ and TIME$ were preserved under a25 - I've not checked. Was I imagining it? lol
