Sending AC signals with IRremote uses up all of SRAM [SOLVED]

Post by AnalysIR »

We got this interesting query from one AnalysIR user from South Africa.
Hi,

I am using IRremote function sendRaw to send the ‘timings’ and it works. It does however take up a lot of RAM memory.

Is there a way I can send the HEX codes instead.

Regards
The solution is as follows:

Yes you can send long AC signals from flash.....

Without much detail...my best guess is:

Try using IRremote version 2.61. (The later versions of the library may have changed some things)
