chicken 630 Posted January 29, 2014 Author Share Posted January 29, 2014 As suggested added board name, my name and revision information. Also moved EXTMOD jumper closer to EXTIN as the two are related, and some general untangling of wires. bluehash 1 Quote Link to post Share on other sites
greeeg 460 Posted January 30, 2014 Share Posted January 30, 2014 PCBs look good to me. Does the slot for the FPC increase the fabrication price? I've always just brought a cutout in from the edge of my boards, or is that what you're doing? Quote Link to post Share on other sites
chicken 630 Posted February 1, 2014 Author Share Posted February 1, 2014 Ordered 10 pieces at Elecrow. Probably will take a long while. And an ad-hoc poll: Of those that consider buying the PCB for the $3.50 quoted by @@bluehash, who would prefer to have the FPC connector included (not soldered!) for an additional $1.20? (I will go with the majority decision) @@greeeg At least at OSH Park, inside cutouts can be drawn on the board outline layer. No extra cost. Quote Link to post Share on other sites
kodi 16 Posted February 1, 2014 Share Posted February 1, 2014 Great job (and yes - please include FPC conncector ). Quote Link to post Share on other sites
chicken 630 Posted March 8, 2014 Author Share Posted March 8, 2014 The boards arrived and they look great, wonderful job by Elecrow! Mounting the display with the FPC through the cutout is a bit fiddly, but other than that everything worked out as planned. I ported my old memory display code to the 2553 and everything worked fine, until I sticky-taped down the display and arranged it to take the picture, when the magic smoke escaped. Literally! With a sizzling sound Either it was dirty contacts (the display contacts had a bit of green oxidation after having spent a year in the junk drawer), or I shorted contacts by yanking too hard on the cable when applying the sticky tape. Anyways, looks like I will have to order a new one. bluehash 1 Quote Link to post Share on other sites
greeeg 460 Posted March 9, 2014 Share Posted March 9, 2014 @@chicken Those boards do look great. Such a shame about your display Having that cutout come all the way to the edge of that PCB may have made inserting the FPC easier, but it would be more exposed. Quote Link to post Share on other sites
chicken 630 Posted March 15, 2014 Author Share Posted March 15, 2014 Success! The new display (LS013B4DN04) arrived in the mail today and after wasting a connector on the first board, just to find out that I also burned out a trace, the 2nd attempt did work without smoke and sizzling noises. Good thing Elecrow sent me 11 PCBs Will coordinate with @@bluehash to get the remaining 9 PCBs (incl. matching FPC connector) into the store. pine, greeeg, dubnet and 2 others 5 Quote Link to post Share on other sites

chicken 630 Posted March 15, 2014 Author Share Posted March 15, 2014 Source code (CCS) and schematics (KiCad and PDF) are now published on Github: https://github.com/astuder/MSP430-sharp-LS013B4DN02-memory-display Next up, writing an Energia library. Is there already one for the BoosterPack that comes with the new FRAM LaunchPad? yosh 1 Quote Link to post Share on other sites

spirilis 1,265 Posted March 16, 2014 Share Posted March 16, 2014 There probably will be soon. I think it was hackaday that reported the upcoming Energia release will support the new Tiva-C Connected LaunchPad and Wolverine boards.

greeeg 460 Posted March 16, 2014 Share Posted March 16, 2014 I have a demo running on my Wolvepad? That uses a frame(+address+padding) buffer. (14*96 bytes.) And then uses DMA to send it all out with no gaps in the spi clk line. The interface between higher level functions (putc, line, rect) and the buffer it self still needs tidying up though. Any device that has enough ram to support this display should have a DMA. But you could still use #ifdef's to run without it. bluehash and chicken 2 Quote Link to post Share on other sites

chicken 630 Posted March 17, 2014 Author Share Posted March 17, 2014 @@greeeg did you use Energia or is it a generic C example? In any case, I definitely look forward to see your code. Adapting it to this booster pack should be trivial (changing around pins for DISP, CS and EXTIN). RAM is going to be an issue with MSP430G2553 though and other smaller MCUs though if one wants to support graphics functionality.. I was already thinking about a REV B that includes a few K of SPI FRAM as dedicated display memory. Quote Link to post Share on other sites
