Thanks for the Info.

Until the rumored EspruinoWifi SD edition comes out :-)

Adafruit has the display as well:

Dear allObjects, did you find the time to use this display with espruino ?
Thanks

Fantastic.
Thanks

Hello Gordon
Quick question before i start a little project. Is UDP supported on a pico with WIZnet as it is on EspruinoWIFI ?
https://www.espruino.com/WIZnet
Many thanks for your answer.

Thanks again.

Hi Gordon
Thanks for your help. How much mem will eval use ? I think i allocate some spare space ?
var evalneed='How much is needed for eval ?'; if (x===undefined) { throw new Error("Not enough RAM for .bootcde"); } else { evalneed=''; // Required for eval // Ugly hack ! eval('var x = E.toString(ST.read(".bootcde")); ST.eraseAll(); ST.write(".bootcde",x); console.log("survived");'); // Here i do a reset via my custom watchdog function. } -
Hi Gordon
After switching to "save to flash" in the IDE, i got a lot of more RAM free. After deleting all files except ".bootcde" and calling compact, nothing new. I do not get flashmemory back.
Then i made a very ugly hack that seems to work!
// ST is the storage object var x = E.toString(ST.read(".bootcde")); if (x===undefined) { throw new Error("Not enough RAM for .bootcde"); } else { // Ugly hack ! eval('var x = E.toString(ST.read(".bootcde")); ST.eraseAll(); ST.write(".bootcde",x); console.log("survived");'); // Here i do a reset via my custom watchdog function. }After the reboot everything is working fine, storage is freed and ready for reuse ;-)

I've added to my wishlist a espruino wifi v2 with more RAM and more Flash ;-)
-
Hi Gordon
Thanks for your answer. I got "not enough RAM for varimg".
Save() is not an option. After the reboot, i get errors in the console. Wifi communication fails.With the save to flash option in IDE i'm not familiar. Do you have a link where i can read about this ?
EDIT: Found: https://www.espruino.com/Saving
Thanks

Hi Gordon
I have several EspruinoWIFI distributed in my house.
The Espruinos are "installed", in most cases difficult to connect via USB again.They all communicate to each other over IP. They know each other over UDP dynamicaly.
Each espruino has a little "core" software saved.
The over all configuration of all espruinos and additional code for different devices (Replays, Sensores, etc.)
are dirtibuted over wifi to the espruinos as needed by the "core" software.Every espruino will get the config and the individual needed additional device code to use and store it on the storage.
So i have a full redundancy. Each espruino has stored the config of all espruinos and several espruinos has stored small code for
different devices like sensores etc.They inform each other about the newest config version and the version of the small code pieces over udp.
If a espruino has a newer version of the config for all espruinos or a newer version of code for connected
devices (Relay, Sensor etc.), the other espruinos will request and get them over tcp too.That is the reason why i use a lot of the storage and get in trouble with it.
That's why i'm looking for a way to wipe out everything except the saved code from the storage.
In that case the config and the needed additional code can be downloaded and stored again.Greetings

Hi Gordon
Thanks for your fast answer. I tried the latest 'cutting edge' build. Same result.
After deleting everything exept the .varimg and calling compact(); again, i do not get any space back.It would be very nice if you could implement a way to delete the flash for reuse without deleting the saved code. Like eraseAll() but without deleting the saved code.
Thanks

Hello Gordon
I tried the storage function on FW 2.00I transfered some files over wifi and stored them using the storage.write();
After deleting all files exept the saved code, i do call storage.compact().But i do net get the space back ?
>ST.getFree(); =22516 // Transferred some files and stored: >ST.list(); =[ ".varimg", "init", "config", "CORE", "DOUT", "SW", "reboot" ] // New Free. >ST.getFree(); =9504 >ST.erase('init'); =undefined >ST.erase('config'); =undefined >ST.erase('CORE'); =undefined >ST.erase('DOUT'); =undefined >ST.erase('SW'); =undefined >ST.erase('reboot'); =undefined >ST.list(); =[ ".varimg" ] > ST.compact(); =undefined // Free ? >ST.getFree(); =9504Thanks for the help.
Sacha
P.S.: A storage.eraseAll() function that removes everything exept the saved code would be nice (As an option for eraseAll() ) ?

Hi Gordon
I would like to let you know that the following seems to work.
When i catch the first Error: "InternalError: Timeout on I2C Write Transmit Mode 2"
i call another I2c1.setup. Everything is working again.A test of 36 hours was successfull.
Sacha

Will do so Gordon.

That's fine Gordon.

I think you should be abe to reproduce it with my isolated code. Just change the linux server to 100ms and enable debug on the espruino side.

It's a bit frustrating. I waited so long for that feature ;-).
My fealing is that there are two problems.
First that something is mixed up resulting in wrong data. Wrong IP and trancated messages.
I'm able to filter that out. I think this has not a crash in result.The second problem, truncating the last chars is resulting in a crash. Like on the last line above.
It's the same that we get in the isolated code above without debug enabled.Sacha

Thanks Gordon
Without the debug enabled, i get the error and crash within a few minutes.
When debug enabled i was also not able to reproduce it with 20 minutes !?I enabled debug to my projectcode. It shows the wrong ip's, fragments of the udp messages and crashes very fast. I think it makes no sense to post the projectcode. It to big.
Here is the output. I only add a console.log of the UDP ip, port and message received. Starting with "UPD Msg: "
The correct source ip is 192.168.68.13
