I've used Module.addCached successfull. Moved it temporarly out of the switch/case statment within a function. It's better than using eval. I can allways see and manage the loaded modules.

My prototype is now able to load and replace modules via xbee without interupting or reset the pico. Very nice!

Will do so. Thanks.

Hi Gordon

No Problem. I transfer additional code via xbee to my espruino's as needed.
I tried to implement this with own local modules. Load them dynamicaly via xbee using addCached. Maybe it's better to implement it via eval.

Hi Gordon

this works:

Modules.addCached('SM',''):

When i call addCached inside a switch statement like this:

var totest='exp';
switch(totest) {
            case 'exp':
                  Modules.addCached('SM','');
                 break;
            case 'nxt':
                 break;
}


Uncaught SyntaxError: BREAK statement outside of SWITCH, FOR or WHILE loop
 at line 1 col 52
...Modules.addCached('SM','');break;case'nxt':break;}
                              ^

Many thanks.

Hello Espruinos

Has someone expiriences with a digital potentiometer connected to an Espruino ?
Should be a 100 kohm.

Thanks

Hi Gordon

USB.on('data',function (e) { 
        USB.setConsole(); 
        USB.on('data',undefined);
});

Is working as expected, but a warning is signaled:

WARNING: Second argument to EventEmitter.on(..) must be a function or a String (containing code)

Hi Gordon
Works perfect. I'm able to use the extra mem.
Sacha

thx

Gordon. Before order a few picos. Has the adafruit picos the extraflash mem ?

Wow, that easy. I did not see where the staring point of the free memory is. Will try it this evening.
Thanks

Freeze. Have to unplug/plug it back to recover.

Hi Gordon,

Running this code:

// Flashtest

function gen_256() {
    var i;
    var str='';
    for(i=0;i<256;i++) {
        str+='X';
    }
    return(str);
}

var bytes256=gen_256();
var f = require("Flash");
var freeFlash = process.memory().flash_start + 511*1024;
console.log(f.getPage(freeFlash));
console.log('LEN:'+bytes256.length);
f.erasePage(freeFlash);
console.log('Nr.1, at '+freeFlash);
f.write(bytes256, freeFlash);
freeFlash+=256;
console.log('Nr.2, at '+freeFlash);
f.write(bytes256, freeFlash);
freeFlash+=256;
console.log('Nr.3, at '+freeFlash);
f.write(bytes256, freeFlash);
freeFlash+=256;
console.log('Nr.4, at '+freeFlash);
f.write(bytes256, freeFlash);
freeFlash+=256;
console.log('Nr.5, at '+freeFlash);
f.write(bytes256, freeFlash);
freeFlash+=256;
console.log('Nr.6, at '+freeFlash);
f.write(bytes256, freeFlash);
freeFlash+=256;
console.log('Nr.7, at '+freeFlash);
f.write(bytes256, freeFlash);

Sorry, not reset() of course. After unplug and replug the pico.

Thanks. Upps. Yes i do not want to use flashmem where save() stores data itself. ;-).
After a reset() the pico worked as expected. Will try to give some code examples this evening.

Hi Gordon

Thanks for your answer. Now i do have some problems with the extra flashmemory. I've wrote 5 junks of 256 bytes. The first ones passed successfull. But then the pico freezed. I have to isolate the code to reproduce it.

Another question. Is your example above using memory at process.memory().flash_code_start save ? Can i start using the 16kb there ?

"flash_code_start" is not documented here:

http://www.espruino.com/Reference#l_process_memory

Many thanks
Sacha

Hi Gordon

I'm able to access the extra page on the pico. Great.
Have a question regarding Flash.erasePage. Will this allways erase the complete page, in this case the 128KB flashmemory ? Is there a way to only erase a part and rewrite that part ?

Thanks

Sacha

Hi Gorden
Thanks for the new LZ4 Version. It worked:

save();
=undefined
Erasing Flash.....
Writing............................................
Compressed 81600 bytes to 42825
Checking...
Done!

={ "free": 3040, "usage": 2060, "total": 5100, "history": 1270,
"stackEndAddress": 536958392, "flash_start": 134217728, "flash_binary_end": 320920, "flash_code_start": 134234112, "flash_length": 393216 }

There seems to be a lot of potential in the compressen method. Maybe there is even a better method in the future.

Is there some documentation with hints how to reduce space ? I.e. use UintArray not strings etc.

Many thanks

Sacha

Hi Gordon

I never tried the code below 1.80.
Sent you an email with the code.
A better compression could be a very nice solution.

Sacha

Hi Francesco, Gordon

Same Problem here with a pico:
ERROR: Too big to save to flash (49803 vs 49148 bytes)

Sacha

Yes the firmware update mode also doesn't worked for me on win10.

Upgraded the pico on a win8.1 station to espruino 1.80.

Now my win10 notebook has no problem. detecting it.

Thx all for the answer. I've connected an original epruino board. It works !
Tried several picos. No luck. I'm going to test it with a different computer with win8.1.
