@peekay123, first of all thank you for you help,
- yes I’m using web IDE to compile the code,
- and as in this topic, I did have added Adafeuit_GFX and Adafruit_SSD1306. (before i have done exactly as here, I did ported Adafruit SSD1306 Lib for test, and positive, Adafruit animation works)
- I’m using SPI OLED, and did this one with arduino pro mini - no problem, for Spark I have implemented pinouts as in this post.
if this will work, I’m planing bring more sophisticated two channel oscilloscope with integrated wave generator, (useful for basic hoppy need).
