Half an hour in and you've already got 24 orders? I think there's some demand. :)

Finding the correct jst connectors is an art. I'm not very good at it, as evidenced by my big box of assorted jst connectors... but I got some in the end!

There's an stm32 cryptographic library: http://www.st.com/web/en/catalog/tools/P­F259409

It would be handy to have access to things like aes as a native module for performance reasons, but I guess it'd have to be an optional inclusion into the firmware add must people wouldn't use it.

@Gordon will you be making any other usb interfaces available? I'm asking because I was thinking it'd be cool to be able to present html files over mass storage to be able to talk to the Espruino without needing drivers. Kind of like how the Nucleo boards show an error file over mass storage when the st-link isn't connected to something.

I've had that too, only on Windows I think, Linux hasn't had the problem

Yeah, it would be a good one to compile in by default, if there's space for it. (Or maybe a candidate for implementing as an installable module, like the new ESP8266 module... but I suspect that's no easy task)

I tried the sd card functions on my Nucleo board yesterday and they were undefined. If I get a chance I'll try compiling firmware for it with USE_FILESYSTEM=1 and give it a go, I've got an sd module I've been meaning to try out...

I think you need to compile the firmware for it yourself, as filesystem isn't defined in the makefile for the pico. See this thread: http://forum.espruino.com/conversations/­252934/

Looks like you get a warning if you set warning_level to VERBOSE. I think I should run all my code through this just to find the errors that nothing else picks up!

@Gordon Awesome. Freeing up flash was why I asked.

My code was minifying, just not completely. It's not a problem with the IDE, or even the compiler I suppose, just a quirk in the process.

Private constants was the main thing that wasn't minifying. One of the reasons was that in one of my functions I was referring to a value not listed in the array, which wouldn't normally be a problem until that function is called. It looks like closure compiler just skipped C and moved on without an error.

Great to see the ESP8266WiFi module done in Javascript. Does NetworkJS require USE_NET in the espruino build?

Just for anyone else having trouble with minifying, errors in your code can affect it. I think that's what was messing me up, I had a couple of things that weren't causing error messages or being picked up by JSHint but they were stopping minification.

That would be great! I don't think there would be massive demand for it, but it would be really handy for some people and great for when porting libraries from arduino.

Okay, thanks, good to know. I suppose that once implemented, features can be ported to internal functions if they prove popular.

Btw, NVRAM/EEPROM is handy for storing things like network addresses for when you're running the same code on multiple devices. But I suppose with Espruino you can just set it into a variable and hit save(). :)

@Gordon - I wanted to ask about this but didn't want to take over that other thread...

Is it better to add on-chip low-level features to jshardware.c or as modules? For something like NVRAM I think that basic read/write, or at least the address would be great to have built in.

Also, I did not know about process.env, it looks quite handy.

Is it something that the configuration for can go into board.py files? It'd be a worthy addition to save people from trawling datasheets for the addresses for their particular board.

This is looking great, I'd be interested in grabbing some too. It'd be great for all the projects I'd like to try with surface mount parts, I've usually stuck with through hole up until now.

I just tried copying the same thing in as I did yesterday and it worked this time. :S I'm sorry, I must be going crazy...

Okay. I've tried that and it won't minimise the "C" private constants. Do you just use simple optimisation?

I just tried to use the Closure Compiler directly through the website and using the minify.js script. Neither way would remove the constants. C's contents stays the same. Is there another method that's used for minifying files for the website?

@Gordon how did you attach the ESP8266 shim? It has a very low profile, are the espruino and the ESP8266 soldered straight to the shim?

Thanks. :) one of the best things about Espruino is that it's so open and usable on other hardware, which made it a clear choice over... other... javascript on MCU options...

It's good to get a closer look of the final pico board. You've done well to squeeze so much onto such a small space in a very usable layout.

It's good to see some pico specific tutorials for first-timers. A page about the adapter shims in general could be good, unless you just want to add to the relevant other tutorials.

Is there a link somewhere for sending money to @Gordon/Espruino? I know that getting any financial contributions hasn't gone well in the past, despite the awesomeness of the software, but it might change as popularity increases with the release of the Pico. I'm specifically asking because I'm thinking of running Espruino on a version of the sensor nodes that I'm building for use in my house, and if I do I'd like to be able to contribute back a bit.

@Gordon do you think you'd keep the same 0.05" header on any future espruino boards? Not necessarily the same pins, but maybe the same functions. It'd be great to build things knowing that they can be used on newer boards. Also, on this track, maybe an original espruino to nano adapter could be useful.

I use Dfrobot for my pcbs and they've been good and cheap. They've done a couple of snap apart boards for me and they worked well.
