So since the past month, I have been working on an OLED display for the Launchpad. It is a 128*64 OLED based on the SSD1306 driver. The booster pack is currently configured as SPI to a MSP430G2452. Th

I am using the new USCI framework on a G2553 and all is working fine after I moved the solder jumpers to the new pin allocations. Thanks gwdeveloper, this is amazing :)

 

My only issue is I don't quite understand what I need to do to create the graphics. I am using LCD Assistant to generate the bitmap from the original source 128x64 mono color file. I exported with Vertical Byte Orientation and Big Endianness at 8 pixels per byte and included the size in the output.

but has converted to Kanji :)

edited main.c to include

imageDraw(tabtoumono, 0, 0);

It starts at the right column but inverts the image in each page.

 

I added it to icons.h and removed the preceding 0x00 from the size .

 

const unsigned char tabtoumono [] = {

0x80, //

0x40, //

Glad this is working out for you. Along with the G2553, I've also tested it on the FR5739, F5529, and F2274. The image conversion software is based from the Image converter included with the F5529 User Experience. The included software only does 102x64 images though. I modified the java source and recompiled to allow for 96x16, 128x64, 128x128 and 160x128.

How about trying this?

Wow, thanks, that worked.... I now have an MSP430 Businesscard :) , never saw an image converter in the F5529 User Experience package, I will have a dig around unless your altered source is available for download. I would like to have a go at porting the 'Fly and Shoot' demo in the QP State-Machine library, its for ARM-3 Cortext but QP-Nano supports MSP430. Turn the OLED Booster Pack into a 'Shootem up Shield'.

Here's one more video. I'm sorting out some details on the graphics library and creating a few more fonts. Mostly numerals and not much text. The Tron Styled font in the video is 32x32. I might create a 32x64 for a scrolling text (possibly twitter?) display.

 

This is a simple, digital clock using the Tron numerals. Those are supposed to be light cycles "racing" and tic-tocking across the top. I'll blame my poor 8-bit graphics on the focus of the camera.

The ram of the G2553 is about topped out. It won't run calculations for using a thermistor.

Yes, I have plans for a frame buffer. Unfortunately, it's not going to use internal RAM of the G2553. The G2553 is limited to 512B where the ATmega328P(arduino) has 2K. Markus' code uses a 1K frame buffer which won't work for this situation.

 

My implementations on the F5529 and FR5739 already have a basic frame buffer. Using the frame buffer does speed things a bit but also makes for a better display. For example; drawing an outline around the display requires using columns 0 and 127 fully, and only 1 bit of each column on pages 0 and 7. Without a frame buffer, writing text to pages 0 or 7 erase the outline even though the font data leaves the 2 LSB and 2 MSB alone. Using a frame buffer, the outline bits remain in place while text is written.

 

Overall, I'm going for maximum usage of the G2553 without overwhelming the poor little mcu.

The drivers and demo program are ready.

I've uploaded everything to github. Please fork it and let's work on a few things together. The circle near the x-axis needs a bit of work. The next update will include text scrolling commands and, possibly, a 24x32 numerals only font.

Is this project moved somewhere?
