I have assembled my makerbuino and started testing games. All the games included in the SD card work without a problem. But testing a couple of specific games in the gamebuino gallery lead to an increased screen contrast and a “NO BATTERY. PLEASE TURN OFF” message.
I am totally sure the battery is fully charged, since it has been charging over night. Also, I can play any other game included in the SD card without a problem for several minutes without getting that message.
The games having this problem (or at least the ones that had the problem with mine) are:
Copter Strike
Tetrino
Sokobuino
FX Synth
Others work without a problem:
Maze
Punkt
Shot Zero
Armageddon
Is there any compatibility issues with gamebuino games and makerbuino? Maybe I’m doing something wrong? Does this happen to anybody else?
Important: If you are going to try any of these games and get the message, you can exit to the menu by quickly pressing the C button after turning on the makerbuino (before the error message appears). Also, after doing so, the message “Flashing loader. Don’t turn off” appears. Do not turn off (I mixed one message with the other and thought I had to turn off). Doing so bricked my makerbuino and I had to use the programmer to upload a game in order to fix it . Be careful
Finally I have found the problem. It seems to be a compatibility issue with the games compiled with the old gamebuino library. It also happens to new revisions of the gamebuino.
If you already use the latest version of the library (v0.2 from Sept, 13 2014) everything is fine. If you don’t, please re-compile your games and update the binaries (.HEX and .ELF) so the settings works properly. If you don’t the Gamebuino fall back on the default values, and it can cause problems especially with the contrast setting, which could make your game un-playable. Thanks!
So after compiling every game with the latest gamebuino library, every game seems to work (I had to front some problems, since some old code does not work with the new Arduino compiler, but it was worth
The charger board has two LED’s on it.
Red indicates that it is charging the battery.
Blue indicates that the charge cycle has completed.
Hope this helps.
Thanks @Eddie, but as I told in the previous post, the error is not related with battery level (even though the message says so). The error is due to an incompatibility problem with games compiled with an old version of the gamebuino library. After downloading the code and compiling it with the newer version, it works without a problem.
By the way, anybody knows if there is a way to close a thread once the problem is fixed?
Luke, can you make the compiled games available somewhere, so that others can just grab them and put them on an SD Card? Would help people on the thread a lot
@nilly, this is an old thread.
In order to fix this on your console, you need to go to the settings app and intimate the “checkup wizard”. Go through all the steps of the checkup wizard and it will set the needed EEPROM settings that will fix this
Thank you for your patience and keep me posted on your progress
Hello, that doesn’t fix the issue I’m afraid. I’ll try compile the projects that has this issue with latest gamebuino library, but if I get any issues I wouldn’t know what to do about it code wise:/. Would like to learn some coding and make a game for buino.
To late I did compile the fx synth, and now it works without the battery warnings. Some other of the games also has this issue can’t remember wich. But recompiling with latest gamebuino library seems to fix the issue
. Be careful
