| Post subject: | Some low-power LCD experiments |
Hello! I thought you might be interested in some experiments I made with COG LCDs. Note that all these applications are written using Texas Instruments' MSP430. However, since I don't use an exotic assembler but plain C, it should be easily portable to any other device, even without SPI capability as shown by the first example. Here is a small graphic LCD with a tiny microcontroller (256 bytes RAM): http://passworld.co.jp/ForumMSP430/viewtopic.php?t=15 Another more advanced LCD since it has 2 bits per pixels (4-level grayscale): http://passworld.co.jp/ForumMSP430/viewtopic.php?t=47 Next, a 16-level grayscale LCD. This one is a lot better and pictures are displayed beautifully even without dithering. http://passworld.co.jp/ForumMSP430/viewtopic.php?t=101 That's it for today. I will also publish very soon a nice TFT with full color capability. Pascal |

Looks like good displays for low power needs. |

Hello Henri! Quote: Looks like good displays for low power needs.
Yes, indeed. I design portable devices, so the power is a key point. One interesting thing: the 101x64 model has exactly the same pinout as the Nokia 3310 (1 = VCC, 2 = CLK ... 6 = GND, 7 = VOUT, 8 = RESET). But it's not the same controller. Nokia uses apparently a Philips controller and this one uses a Samsung S6B0725A. Pascal |
