Hi - Thanks for reporting but I can't replicate.

I just pulled v1.0.4 of lib via lib manager, and compiled for Arduino Nano (ATmega328)

Arduino v1.8.8 Windows 10

So it sounds like we're very close to similar platforms. I'm not sure what the problem is but it's possibly related to your other reported issue.

tnsolley commented 5 years ago

I found from a similar issue with the Picaso_Const4D.h file (and RTClib.h) that I suspect both libraries, SSD1320_OLED.h and SFE_MicroOLED.h, having this naming conflict because they use the same variable. I found with the 4Duino system that changing one's use of OFF and ON to OFF4D and ON4D fixed that; I suspect something similar needs to happen here, though I'm in no position to suggest which library does what...

nseidle commented 5 years ago

Thanks for coming back to describe a fix. According to your original post, the conflict was with this line. But the SparkFun typedef enum CMD does not contain ON or OFF so are you describing a new issue?

One way to avoid your original issue is to change our CMD to SSD1320_CMD.

tnsolley commented 5 years ago

@nseidle Sorry, I didn't clarify well enough. I assumed that the use of CMD was conflicting between SSD1320_OLED.h and SFE_MicroOLED.h; I'm actually no longer sure that's the case. After posting, I did a bit of tinkering; looking closer at the reported problem (Arduino IDE feedback, above) I noticed that the files referenced were being pulled from my \User\...\Documents\ folder and not from ...\Program Files (x86)\Arduino\. I've since removed the named libraries folder from Documents and copied all the required libraries to their proper location under \Program Files (x86)\. Sadly the issue didn't go away, in fact it seems to have gotten worse. I am (still) getting another issue, but that appears to be related-to the Qwiic Micro OLED example-function printTitle(), which I'll reference shortly. Not sure if related...

Output after changing SSD1320_OLED.h 'CMD' to SSD1320_CMD:

Renaming the entirety of typedef enum CMD{} seems to have helped, though, in SSD1320_OLED.h --- I no longer get the reported error. TL:DR; Folks using both SSD1320_OLED.h and SFE_MicroOLED.h may need to rename their typedef enum CMD{} and it's contents, as I did for SSD1320_OLED.h;

typedef enum SSD1320_CMD {
