I was able to get Nybble configured with #define MAIN_SKETCH commented out, but upon adding it back in, I have the error
Arduino: 1.8.19 (Windows 10), Board: "ATmega328P (5V, 20 MHz) NyBoard V0_1"
text section exceeds available space in boardSketch uses 31342 bytes (102%) of program storage space. Maximum is 30720 bytes.
Global variables use 1595 bytes (77%) of dynamic memory, leaving 453 bytes for local variables. Maximum is 2048 bytes.
Sketch too big; see https://support.arduino.cc/hc/en-us/articles/360013825179 for tips on reducing it.
Error compiling for board ATmega328P (5V, 20 MHz) NyBoard V0_1.
I have V0_2 of Nybble. I've seen the similar post https://www.petoi.camp/forum/basic-assembly-and-setup/opencat-sketch-too-big-solved?origin=auto_suggest about this same issue, but I have the most recent Open Cat code with the fix. My Nybble board seems to have less storage than theirs.
Any help is appreciated!
The NyBoard V0_2 is designed at least 4 years ago. We have improved a lot in both hardware and software. So we recommand to replace this old main board with NyBoard V1_X (NyBoard V1_0, NyBoard V1_1 or NyBoard V1_2.
