How to compile with oled support? (ssd1306)

[techhazard]

I have added an ssd1306 oled screen on the left side of my dilemmav2 and would like to use it do display things (e.g. which layer is active). I think I have added the necessary settings, but I am not gettiing QMK to compile.

With this PR/question I want to have a minimal working oled setup (whether this PR is merged or not).

I have tried the following things:

1. compile bkb-master without changes (commit f4166fca22): this works

2. add ENABLE_OLED = yes to keyboards/bastardkb/dilemma/3x5_3/rules.mk: I get the following errors:

platforms/chibios/drivers/i2c_master.c:74:24: error: 'I2CD1' undeclared (first use in this function); did you mean 'I2C1'?
   74 | #    define I2C_DRIVER I2CD1
      |                        ^~~~~
...
platforms/chibios/drivers/i2c_master.c:37:26: error: 'B6' undeclared (first use in this function)
   37 | #    define I2C1_SCL_PIN B6
      |                          ^~
...
platforms/chibios/drivers/i2c_master.c:40:26: error: 'B7' undeclared (first use in this function)
   40 | #    define I2C1_SDA_PIN B7
      |                          ^~

3. add #define RP_I2C_USE_I2C1 TRUE (and undefine before it) to keyboards/bastardkb/dilemma/3x5_3/mcuconf.h: The error for I2CD1 undeclared disappears, but the ones about B6 and B7 remain.

What kind of settings am I missing?

Hey,

I just noticed this, sorry for the delay.
If still not solved, I recommend dropping by the discord.

OLEDs are not officially supported, so we're not going to integrate this.
Instead, you should add it to your userspace or qmk fork.
