OLED Carrier Board

Hi all,

Well I’m back from vacation, and I’m back to my OLED project…

I’m still stuck with this board and cannot pass Go!

I plan on using this carrier with the following options.

#1. 3.3v power (use booster)

#2. SPI (using a pic uP)

What I have done so far.

#1. I have attached 3.3v to the Vcc pin

#2. Attached ground to the GND pin across from the EN pin

#4. Connected BS1=ground - serial mode

#5. Connected BS2=ground - serial mode

connected the following pins…

#define SCLK PIN_C5 /* SCLK = D0 pin */

#define SDIN PIN_C4 /* SDIN = D1 pin */

#define DC PIN_A5 /* DC = D/C# pin */

#define CS PIN_C3 /* CS = CS# pin */

#define RES PIN_A4 /* RES = RES */

#define TRIGGER PIN_B7 /* used for trigger */

According to the specs, if RES=LOW, the OLED controller will be init’d, page 15 of the specs.

Soooooo, at a minimum, if I toggle the RES pin with a delay, I should at least see some power being used my meter, yes? I’m not seeing anything!

I just attached a small LED to the same power source (same breadboard) and it came up and the meter read “0.17A” @ “3.3v”, stop the LED and the reading goes to “0.0” to amps.

Any thoughts?

I hooked up a functioning OLED carrier without any data connections, but with vcc, gnd and reset. The current consumption of the board read zero at the power supply. My Fluke multimeter claimed the current draw to be around a microamp… So I don’t realy expect you to see any fireworks until the display has be programmed.

Moose, et al.,

You are correct, once I talked to the unit and activated it, the power usable went up!

Thanks!
