I want to use an SSD1306 display with a LPC1549 mcu

[sergedemaseneer]

I know that there are different possibilities to use this kind of display with Arduino based boards but for a small project i would like to use the LPC1549 (which has all i need aboard) in combination with an small SSD1306 based display.

Does anyone know if there is a ready to use (or to port) library available?

I found a processor expert library for kinetics processors but it seems not to work with lpc controllers.

Many thanks in advance for helping me with this issue.

Thank you all for the help. Since I use I2C bus now for about 30 to 35 years I know it very well so that part of the code should not be a problem.

Omar I will check the links and Erich I will certainly have a look at your driver.

Hi Serge De Maseneer,

I assume you are going to use the I2C version of the SSD1306, right? Otherwise this is what I recommend.

I'm using that display in many projects (see SSD1306 | MCU on Eclipse ) and as well for LPC (e.g. 845). I have built a library both for Processor Expert (maybe you are referring to that one) and with the NXP MCUXpresso SDK.

You find the driver on GitHub (McuOnEclipseLibrary/McuSSD1306.c at master · ErichStyger/McuOnEclipseLibrary · GitHub ): this one is generated by PE but used by the SDK code, so you can easily use it with any C code: all what it needs is an I2C interface/driver.

This is fairly easy for a device which is supported by the NXP MCUXpresso SDK: as far as I see your LPC1549 is not supported, so you would need to provide your own I2C library and tweak the things a bit.

I hope this helps,

Erich

Hello

Unfortunately, there isn't a specific library for this display. I suggest you use these examples as a reference for your project:

These examples are not designed for your device but they are a good starting point to make the display work in the LPC1549. 

I apologize for the inconvenience this may cause you, if you have more questions do not hesitate to ask me.

Best regards,

Omar
