Code: Untitled.txt Select all
I am trying to implement a web radio streaming device with ESP32 (DEVKITV1 from Aliexpress) and UDA1334A DAC. The problem is that when compiling in the Arduino IDE (2.3.3 nightly) I get the "sketch too big" error:
[quote]Sketch uses 1356645 bytes (103%) of program storage space. Maximum is 1310720 bytes. [/quote]
The sketch from this source https://electropeak.com/learn/interfacing-uda1334a-i2s-stereo-decoder-module-with-esp32/ is actually garbage, does not even compile. I made it try to compile (with the too big error) by adding the missing "()" in every single function.
The sketch from this source https://how2electronics.com/simple-esp32-internet-web-radio-with-oled-display/ actually tries to compile (gets the too big error), I even stripped it from the display part to try and save space.
In the Arduino IDE I tried to select both "uPesy ESP32 Wroom DEVkit" and "DO IT ESP32 DEVkit V1" as boards, no difference (still get the "sketch too big" error).
Any ideas as to why a sketch supposedly working (from a tutorial) does not compile?
EDIT: This is the full code that tries to compile (but still is flagged as too big of a sketch):
