Hi, I know this thread has been started before but the others have no solutions that fix this for me.
Hooked up Serial OLED Display (AXE033Y with DS1307 clock upgrade) to PICAXE 18M2 High Power Project board
Originally used serial mode and connected the "in" and "out" of the AXE033Y to 2 pins of the PICAXE 18M2. All worked fine- could set time, alarms and all was good.
The display worked fine and displayed text as I wanted.
However I required 2 alarms so wanted to use i2c mode for the PICAXE to read the time continuously and check if the alarm time was reached while continuously displaying the time on the OLED.
I put a jumper across the mode connectors to change it to i2c and changed the serial leads to the SCL and SDA format (B.1 and B.4 on the PICAXE)
Loaded up the i2c test code (Hello!123) from the datasheet and waited for program to run. Nada.
The display was blank, i've checked continuity between pins on the master project board 18M2 and the slave OLED 18M2. Both boards are powered up 5V regulated.
The OLED board has the power connections shorted since the diode was causing a voltage drop when I ran it in serial mode and the time wasnt advancing.
Any suggestions?
Thanks all.
