Compiling code for Arduino Pro or Pro Mini #2

Closed pandrews255 closed 6 years ago

pandrews255 commented 6 years ago

I'm sure it's something that I'm doing wrong, but it seems this code is too big for a pro mini 328.

Error: Sketch uses 35516 bytes (115%) of program storage space. Maximum is 30720 bytes. Global variables use 1264 bytes (61%) of dynamic memory, leaving 784 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 Pro or Pro Mini.

Attached is how my Arduino program is setup. untitled

Since you're using Atom, I thought I'd give it a try also and after installing that, it looks like I'm getting a similar error:

Error: The program size (29232 bytes) is greater than maximum allowed (28672 bytes) *** [.pioenvs/sparkfun_promicro16/firmware.elf] Explicit exit, status 1

I think after a little google action, the issue is a 2048 byte difference between the Pro Mini (Maximum 30720 bytes) and the Pro Micro (Maximum 28672 bytes)... Time to get cutting.

wrong version of the lmic. Delete the one you use and go grab the one from here: https://github.com/matthijskooijman/arduino-lmic
