RobG 1,892 Posted February 2, 2012 Share Posted February 2, 2012 After making my N6100 Color LCD Booster Pack, I thought that it would be better if I made it more universal by supporting different displays. So here's my v2 board, which now supports JD-T1800 display. Supported displays: JD-T1800 1.8" Color TFT display, 160x128, ST7735R driver (~$6.50 on eBay, $9.95 Adafruit.) Nokia 6110, 1.8" Color CSTN display, 128x128 Other Nokia LCD that will work with this board (need to verify): 6100/5100/3100 6070/6060/6125/6101/5200 I believe those will work too: 3200/6610/7210/7250 Works with USI and USCI 2 buttons and 2 LEDs (20pin MCUs only) JD-T1800 can be mounted in 2 positions (one will cover switches, the other will make LCD extend beyond the board.) Place for 2 memory chips (SRAM or EEPROM,) one with HOLD. Charge pump to power N6100 backlight (7660 compatible or TPS60403) Are there any other 3.3V (or 5V) SPI displays I should consider? larsie and alsenin 2 Quote Link to post Share on other sites

RobG 1,892 Posted February 3, 2012 Author Share Posted February 3, 2012 Thanks! I think I will add N6060, you can pick one up for $2.99 on eBay (not too excited about the connector though.) Quote Link to post Share on other sites
RobG 1,892 Posted February 3, 2012 Author Share Posted February 3, 2012 Added 22pin connector to support Nokia 6070/6060/6125/6101/5200 LCDs. See original post. Quote Link to post Share on other sites
RobG 1,892 Posted February 5, 2012 Author Share Posted February 5, 2012 How about SD card? Still have some room left, maybe I should also add a DAC (for playing audio files from SD card?) [image removed, see below] Quote Link to post Share on other sites
bluehash 1,581 Posted February 5, 2012 Share Posted February 5, 2012 SDcard sounds like a better choice for image/font storage. Quote Link to post Share on other sites
RobG 1,892 Posted February 14, 2012 Author Share Posted February 14, 2012 I think I am done. Removed 7660 charge pump, added SD card. Here are the 3 types of supported displays. Quote Link to post Share on other sites
RobG 1,892 Posted March 2, 2012 Author Share Posted March 2, 2012 The first version of the board is in and assembled. TC7660 is used to power backlight and no memory chips are installed. Time to fire up CCS. larsie 1 Quote Link to post Share on other sites
bluehash 1,581 Posted March 2, 2012 Share Posted March 2, 2012 Is it displaying something or is it only the backlight. Looks sweet Rob! Quote Link to post Share on other sites
RobG 1,892 Posted March 8, 2012 Author Share Posted March 8, 2012 Didn't finish programming the first one when the version 2 arrived. Looks like my weekend just filled up. bluehash and GeekDoc 2 Quote Link to post Share on other sites
SugarAddict 227 Posted March 8, 2012 Share Posted March 8, 2012 I want... just so I can throw all the random LCD's I have on it to see if they work lololololol Quote Link to post Share on other sites
RobG 1,892 Posted March 13, 2012 Author Share Posted March 13, 2012 First try, we've got color! Well, it's all gibberish now, but it's a start. ST7735's documentation has 167 pages The display below is 1.8" TFT 128 x 160, JD-T1800 bluehash, cubeberg and GeekDoc 3 Quote Link to post Share on other sites
cubeberg 540 Posted March 13, 2012 Share Posted March 13, 2012 Looks really good! Any idea what a full kit would cost? Quote Link to post Share on other sites
RobG 1,892 Posted March 13, 2012 Author Share Posted March 13, 2012 The minimum required to get JD-T1800 display to work is: PCB - not sure how much b# will charge but I am guessing $5. Display - $6.50 on eBay Headers - $0.15 47k 0805 resistor and 1n 0805 capacitor 0ohm 0805 resistor (soldering pads will work just fine) Optional things: 2 tactile switches 2 0805 LEDs with 2 resistors ~200ohm SPI memory with 100nF 0805 capacitor SD card holder For Nokia displays you will need: TPS60403 charge pump with 3 0805 1uF ceramic capacitors - ~$1.00 10 pin or 22 pin socket - ~$0.60-$2.00 Quote Link to post Share on other sites
bluehash 1,581 Posted March 13, 2012 Share Posted March 13, 2012 You are right on the PCB. $5 as long as it is under 5by5 cm Quote Link to post Share on other sites
