chicken 630 Posted January 26, 2014 Share Posted January 26, 2014 As discussed in this thread, I took a first stab at a Booster Pack for the 1.35" SHARP Memory Display. As suggested by @@greeeg, I added two footprints: FPC connector (on the back) zebra strip connector (on the front) While the outline is for the 1.35" variants (LS013B4DN01, LS013B4DN02, LS013B4DN04). The 1.28" (LS013B7DH03) and 1.26" (LS013B7DH01) displays should work too as the FPC cables are of similar length and zebra footprints are identical. The smaller, circular displays might work, but the length of the FPC cable might be too short. The larger displays have the same FPC cable, but will overlap with the LaunchPad connectors. I could fit the next size up (2.7", LS027B7DH01) when rotating the screen 90 degrees. I only supply 3.3V. The current small-sized displays are all 3.3V. The older 1.35" versions specify 5V supply voltage, but in my experience work fine with 3.3V. I don't know about the larger displays. Connections are as follows: SCLK -> P1.5 (SPI CLK) SI -> P1.7 (MOSI) SCS -> P2.5 (SPI CS) DISP -> P2.0 (display on/off) I did go with the BoosterPack recommendations for SCS and DISP, but I'm considering to put them somewhere on the upper 14 pins to maintain compatibility with my original code which was for the MSP430G2231. Not yet connected are EXTMODE and EXTCOMIN. These are to control how the LCD polarity-toggling is driven. If EXTMODE is high, toggling is done through EXTCOMIN, otherwise it's done through SPI. I might pull EXTMODE low with a resistor and expose jumper pads to change the configuration. I filled the front plane with 3.3V and the back plane with GND. The horizontal shape at right below the zebra strip pads is the cutout for the flex cable. Any input is greatly appreciated. yosh 1 Quote Link to post Share on other sites
