i have a project where i would like to combine Adafruit items:
ID: 938 Monochrome 1.3" 128x64 OLED graphic display
ID: 746 GPS module MTK3329 edition
ID: 254 MicroSD card breakout board
i'm using the recently downloaded from github Adafruit libraries:
with the ssd1306_128x64_spi sketch i can control the display
with the (gps) parsing sketch i can parse gps data
but when i want to combine the 2 something goes wrong, and gps data no longer gets parsed and the display is blank
sometimes the splash screen get's displayed and then freezes.
to avoid this problem i tried to use the ssd1306_128x64_i2c sketch to start from but with this sketch the display remains blank.
i've followed the http://learn.adafruit.com/monochrome-ol ... s/overview
tutorial but this display does not get mentioned in the wiring section, maybe i have a wrong wiring?
the pin's i've wired for the i2c sketch are
Data - A4
Clk - A5
Rst - D4
Gnd - Gnd
and i'm using an Arduino Uno
