Me No Dev
use this to decode it
Helio Machado
Should I use Arduino IDE, or can I use PlatformIO?
Me No Dev
Arduino IDE
it's a plugin for it like the one for uploading SPIFFS
Helio Machado
But, I've built the code with PlatformIO. Where does Arduino IDE store the compilation results?
Me No Dev
open the ide, enable verbose output for build in IDE's settings
then build an empty sketch (select the proper device)
and it will tell you the location of the temp folder that it used

Is that what you want?
Is this output well?
Me No Dev
how did you run it though?
Helio Machado
I built a empty sketch, seen the build folder, and replaced the elf and the bin of the empty sketch with the ones from the platformio build.
Me No Dev
funny it does not show the line numbers
but yes that should be the correct output
Helio Machado
Maybe @ivankravets should think how to implement the stack trace decoder. If he does the interface, I'll do the backend.
Me No Dev
exception seem to be in spiffs itself
Helio Machado
Maybe my bad, adding a conditional to see if file "exists" (even if I upload it).
Helio Machado
Spiffy said that the file exists.
@me-no-dev: Maybe you could try to reproduce the problem?
webServer.on("/memory.txt", [](AsyncWebServerRequest *request) {
    if(SPIFFS.exists("/codes.txt")) {Serial.println("Existssssssssssss");}
    request->send(SPIFFS, "/codes.txt", String(), true);
Me No Dev
request->send(SPIFFS, "/codes.txt", String(), true); checks if the file exists also
maybe something is wrong with the file or spiffs itself
@skorokithakis looks good thx

Hello I have a question.
on ESP12F function spi flash write (. I use the address space of 0x0fc000 to 0x3fbfff. The question which addresses to use for ESP01 (1MB) if it works in the variant 64kb SPIFFS. ?? (I'm not using the application SPIFFS)
Me No Dev
1MB - 16KB(system settings) - 64KB = start of the space you are asking for
that is beginning SPIFFS in this case will be at 0x14000
I mean functions spi_flash_write
Stavros Korokithakis
@tzapu I'm a bit hazy as to what the wifimanager does, i thought it was some sort of web AP but that doesn't appear to be the case

For those who wish Internet Radio using ESP-VS1053 : http://www.esp8266.com/viewtopic.php?f=6&t=2688&p=46092#p46092
Michael Miller
@martinayotte That would imply they are accessing the buffer as a 32bit type wouldn't it? Maybe the buffer should be declared as uint32_t [8]?
Martin Ayotte
@Makuna , Unfortunately, the Radio code handles uint8_t, not uint32_t. It is the SPI.writesBytes() that requires alignment enforcement.

I'm trying to use the coroutine code that is already written for my system by creating a cooperative threading mini-system to simplify my code. For that it would be extra nice to be able to override the delay function when running inside a coroutine from the normal delay to the coroutine switching out. For this I need to make the delay function a weak symbol. Will such a change be acceptable for the project?
Obviously, I'd be happy to contribute the cooperative threading as well
@helio check if you're using any function that yields. E.g. file->readstring is not possible inside async handler.
OT: does anyone have experience with using LoRa radio, e.g. on Adafruit Feather? What is a good starting point for hw and sw?
Lars Englund
Can I use the ESP RX pin for GPIO while still using the TX pin with Serial.println etc?
Jan Chrillesen
larsenglund: If you just need to transmit you can use GPIO 2 for TX. Search for Serial1 on https://github.com/adafruit/ESP8266-Arduino
Lars Englund
@janchrillesen All other pins are taken in my design :) But I just tried using gpio3 after running Serial.begin and it seems to be working just fine!
