Demo program radarchart take a long time to start

[shree]

I got my GD3 from the Kickstarter campaign. I am using it with the Arduino IDE, and an Arduino UNO clone.

I find that demo programs sometimes take a long (and variable) time to start.

e.g. radarchart. When I upload it from the IDE, it seems to take a long time to start - sometimes more than 30 seconds. Sometimes, the same program starts in 3 seconds. In general, it seems to be taking a variable time to start every time.

The behaviour is similar if I use the reset button - or power on the Arduino with USB.

Any ideas on what could be going on here ?

Possibly the microSD card detection is stalling. Maybe try:

(1) Putting a microSD card in the slot
(2) Changing the startup line:


GD.begin();

to

GD.Begin(~GD_STORAGE);

to disable microSD detection.

Yeah! I didn't have an SD card in my Gameduino. That change works for me.

Now got an SD card & running all the example programs.  It's a joy to use. Thanks for your work!

Oh good - glad it's all working.

Raised issue to add timeouts to the library's microSD detection:

Thanks. I think the worst case 500 ms timeout (mentioned in issue description) is good. This will ensure that everyone has a good experience.
