Arduino exemple keybusReader si to big for UNO

[BriceDet]

Hi, The last develop version of arduino keyBusReader exemple are too big for the arduino UNO. Could it add in comment of this exemple? (I can do this but I want to be sure that's the good way).

Thanks

Strange, I'm not seeing this issue, testing with Arduino 1.8.13:

Sketch uses 31946 bytes (99%) of program storage space. Maximum is 32256 bytes.
Global variables use 950 bytes (46%) of dynamic memory, leaving 1098 bytes for local variables. Maximum is 2048 bytes.

Is there a difference in compiler/environment/etc? It'd be good to track down.

Under 83%, software flash crashed... Only for me? (It's an official arduino uno)

[taligentx]

Under 83%, software flash crashed...

So you get a crash if flashing a file over ~26kB? I haven't run across issues filling the flash memory on the atmega328p - even the times when I've wiped out the Arduino bootloader to use the entire 32768 bytes of flash instead of the normal 32256 bytes with the Arduino bootloader.

[BriceDet]

In fact i didn't identify the root cause: If I flash the current version, the flash process stop (not responding). If I comment some line in order to try to have lighter build, the flash process completed. May you have an idea? If you said me that possible to flash this size of builds, I'll look for another reason 😅

[taligentx]

It'll be a while before I can test this, what is the final compiled size of KeybusReader for you?

[BriceDet]

after my last git push (event buffer decoded) :

Arduino: 1.8.12 (Windows 10), Board: "Arduino Uno"

Sketch uses 34056 bytes (105%) of program storage space. Maximum is 32256 bytes.text section exceeds available space in board

Global variables use 972 bytes (47%) of dynamic memory, leaving 1076 bytes for local variables. Maximum is 2048 bytes.
Sketch too big; see http://www.arduino.cc/en/Guide/Troubleshooting#size for tips on reducing it.
Error compiling for board Arduino Uno.

With the lase develop version :

Sketch uses 31930 bytes (98%) of program storage space. Maximum is 32256 bytes.
Global variables use 950 bytes (46%) of dynamic memory, leaving 1098 bytes for local variables. Maximum is 2048 bytes.

compile process is ok, but upload not working : the IDE freezed at this step

and the upload button stay pressed

after (maybe) 5 minutes, this error was triggered

With "upload verbose" option checked, the last sentence is :

Sketch uses 31930 bytes (98%) of program storage space. Maximum is 32256 bytes.
Global variables use 950 bytes (46%) of dynamic memory, leaving 1098 bytes for local variables. Maximum is 2048 bytes.

Hi @BriceDet - I've consolidated some code in dscKeybusPrintData.cpp in the develop branch to reduce flash usage. This includes zone expander decoding but your event buffer decoding (thank you!) is still on the TODO list. Current KeybusReader compile size for the Uno:

Sketch uses 28514 bytes (88%) of program storage space. Maximum is 32256 bytes.
Global variables use 950 bytes (46%) of dynamic memory, leaving 1098 bytes for local variables. Maximum is 2048 bytes.

This is experimental as I won't have access to the test hardware for another few weeks so feedback would be great if you get a chance to try develop. This is still above the 83% you mentioned as causing crashing, but I haven't seen the same issue my Uno or Nano originals and clones - are you able to test with a different Arduino module?

[kricon]

Flashed current develop version on genuine Arduino Uno, everything works, took all logs today thru it:

Sketch uses 29872 bytes (92%) of program storage space. Maximum is 32256 bytes.
Global variables use 957 bytes (46%) of dynamic memory, leaving 1091 bytes for local variables. Maximum is 2048 bytes.

Then I've tested commit 640d71c from Oct 30 just in case and it also compiled, flashed and run nicely:

Sketch uses 31946 bytes (99%) of program storage space. Maximum is 32256 bytes.
Global variables use 950 bytes (46%) of dynamic memory, leaving 1098 bytes for local variables. Maximum is 2048 bytes.

I also have non official Arduino Nano clone, but I don't have Mini USB cable handy right now so I cant verify it at the moment.

Very strange comportment. I'll buy another arduino next months...

[BriceDet]

let me closed this issue. It may due to my hardware.
