Hi there,

I see to have an issue uploading any font larger than 1000byte. So far i get success with fur25n[798] but moving up to fur49n[2683] results in an error. "dataset too large!" I thought the limit was around 3500 bytes?

Using the standard arduino libaru to upload the font. Display is OLED 160x128 v2 firmware 3.7.

Thank you. 

 It supposed be work, the "data too long" error may be caused by other function of data downloading, did you use our latest Arduino lib and set:

#define Ver 37

at the top of sketch?

For firmware V3.3 and later, the 2 bytes sequence of data size are reversed than older version.

 I can confirm that: add

#define Ver 33

at the top of sketch will fix the problem.

#define Ver 37

This fixed the problem. Thank you.
