Arduino Uno

[thijsforel]

Hi,

Trying to use the library for the first time. Trying the SimpleDimmer example (provided with the Library) Arduino IDE says:
"Global variables use 2337 bytes (114%) of dynamic memory, leaving -289 bytes for local variables. Maximum is 2048 bytes."
What's up with that?

Hello, please try to rename the library folder on "RBDdimmer" and restart your Arduino IDE !

Hi, i have the same issue.
It seems that the RBDdimmer library alone is too much for the 2KB SRAM of the arduino uno. It uses too many global variables.
With the arduino mega as selected board, which has 8KB it compiles just fine.

Is this library compatible with Uno and Nano boards, as described in the README?

this works for atmega 328 it only uses arduino library but i need help aswell i want to keep the dim constant where this code fluctuates

digitalWrite(AC_LOAD, LOW); // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC
}

void loop() {
for (int i=880; i <= 902; i++){

does not run as good as RBD codes on at2560 r3

Hello !
I have the same issue as mentioned by @thijsforel with my Arduino Uno (with the SimplePotentiometer example) and your "AC Light Dimmer Module".

"Arduino IDE says: Global variables use 2411 bytes (117%) of dynamic memory, leaving -363 bytes for local variables. Maximum is 2048 bytes." So, impossible to compile the sketch.

As asked @rammnco, is this library compatible with Uno and Nano boards, as described in the README ?

Thanks for your help,
Bests.

[JimmyBondi]

Same here...
I also would like to use this with an ATMega328 based Arduino.

@rammnco @Gauthieer @JimmyBondi
Did you try to rename the library folder on "RBDdimmer"?
Arduino\libraries\RBDdimmer

[rammnco]

@VSneg
Yes, I have the folder named that way ("RBDdimmer").
I have tried it with the c and header files directly under this directory too.

Can this really be related to the library name though? The message says its about the global variables leaving no space for local variables...

It seems to be loaded well , because the sketch compiles just fine if I select a board with a bigger SRAM (like Arduino MEGA).
Just the Uno does'nt work, due to it's limited space. Same error mesasge like the others above.

[Gauthieer]

@VSneg
Yes, like @rammnco, my library folder's name is "RBDdimmer"... I also think it's just because the sketch is to big for Arduino Uno...Have you got a solution for that ?
Thanks.

[JimmyBondi]

@VSneg
Yes. I also tried it with different IDE Versions. (1.8.5, 1.6.12 and 1.5.8)

We made new libarary please can you try and give us feedback )

Auch mit der neuen Version:
Globale Variablen verwenden 2139 Bytes (104%) des dynamischen Speichers, -91 Bytes für lokale Variablen verbleiben. Das Maximum sind 2048 Bytes.
Nicht genug Arbeitsspeicher; unter http://www.arduino.cc/en/Guide/Troubleshooting#size finden sich Hinweise, um die Größe zu verringern.
Fehler beim Kompilieren für das Board Arduino/Genuino Uno.

Hi, I try to connect an Arduino Nano Every but the library don't work with this version of Arduino, anypeople have idea how I can operate with this library in this Arduino Model?
Thanks in advance.
Regards.
