Fantastic job on the faces! Agreed that the display is not the speediest and a reminder to anyone wanting more speed to look into @fanoush's work for the P8 to have a buffered solution (with fewer colours perhaps, but capable of refreshing a sweeping second hand).

And thank you for pushing the driver forward.. it was just to get it off the ground and I haven't put more time into it since. Glad you freed up the memory (BTW: what are you using to profile the driver? I'm really not well versed in optimization, and I really need to be!) and cleaned up those timeouts. I think I'll just grab your baseline from here..

It really is a nice screen isn't it? and yes, much bigger looking than its spec. I just bought another SN80 recently, with DaFit firmware from AE, and just ran through the full process:

• Used DaFlasher to upload DaFitBootloader23Hacked.bin
  
• Used nrfConnect to upload FitBootloaderDFU2.0.1.zip
  
• Used nrfConnect to upload fanoush's p8-sdk11-to-sdk12.zip
  
• Used nrfConnect to upload jeffmer's image (github.com/jeffmer/WatchApps/firmware) espruino_2v11.1.5.4_SN80.zip
  
  

I used my own driver set for now, but all works perfectly. Nice work, @jeffmer!

A caution for anyone wanting to get an SN80 though.. my "new" one has a slightly misaligned LCD ( a vertical line from 12:00 to 6:00 is tilted a few degrees). Nothing tragic, but unfortunate as analog watches won't align to the tick marks on the bezel! Could be selling off QA rejections?

That's great! I actually am running with my own driver for the moment... not as good, but for setPixel, I just set the color and go.. I don't buffer even the one line; so it's slower but I got it to work. I tried taking out double buffering but it didn't work for me... but I'll try your version for sure.

As for the button, I did get it to work.. According to atc1441's notes, btn1 is D9, and that works as long as you pull D17 high. I'm sure there's a less hacky way, but I defined two buttons, the second one being D17, and pull it high:

 'BTN1' : { 'pin' : 'D9'} ,
 'BTN2' : { 'pin' : 'D17', 'pinstate' : 'IN_PULLUP'} ,

well, it's definitely the setPixel f().. I wrote a super simple one (chunk-less) and the screen now displays fine. No idea why the chunk_buffer is not working for me (it works on this code base with the P8). I'll investigate further, for now, I have a working screen. Thanks to all!

@jeffmer Thanks, that was it of course... however I'm running into some more weirdness now.. I have a test pattern I'm writing to screen (bitmap font, vector font, lines, filled/unfilled shapes and an image. When I use the JS-only method to drive the display, everything displays, albeit very slowly.
pure JS version
When I use lcd_spi_unbuf (with proper command), filled shapes and drawRect work..every other horizontal line seems to work, and drawCircle/drawPoly do NOT seem to work at all.
lcd_spi_unbuf version
I must be missing an initialization of something.?

The message is displayed by the Launcher app. On my watch (Bangle2) it's named launchb2.app.js, but it's minified. You can pull an unminified version from github, remove that line, and push it to your watch.

that is likely it... thank you. I'll try shortly, but that sounds right. I'm glad it's me being absent minded and not something really wrong with the watch!

Well I'm looking forward to that! Glad to hear it won't be secret for long...

Another Q... this SN80 is an interesting beast; it seems to be nearly identical to the P8s in the wild (same pinouts, samed shared SPI for display / ext flash). I'm using @jeffmer 's code for the shared SPI (basically his P8 build untouched except for the name), and I'm getting an SPI error during display initialization.

Uncaught InternalError: Timeout on SPI0-lock

When I was running the firmware without shared SPI (no ext flash) I didn't get this. I assumed that this code would be safe regardless if it's shared or not (it errs on the side of caution by pausing the other device). My impression is that this is saying "SPI is in use or not ready". Am i interpreting that correctly? (BTW: the external flash works, I'm able to save files and read them back.. but this started as soon as I began working with both display AND spi flash).

Any insights or thoughts welcome...

You reverse engineered @Gordon's remark! Brilliant!! That board looks VERY interesting indeed. It's resisting my attempts to Google more info though... and we don't want to get Gordon in any trouble, so I'll shut up now. But intriguing....

OK, good... thank you. I'd hoped that the shared SPI wouldn't be a huge deal, as you say, just set the pin, make a call, restore. A good experiment for me :-)

@fanoush Hello again... I'm interested in using the 2MB flash as "Storage" for the F07. Will I have to build that in via board file, or can I set that up in JS code? I realize I'll have to do some magic switching since it shares SPI with the accelerometer. Is this straightforward or am I asking for trouble? LMK when you can, thanks (as usual)!

I'll gladly thank @fanoush for all his work in this project, and have many times. I wear his code on my wrist every day (currently an F07)! I was thanking YOU @Robin for your empathy in my situation. I am currently chatting with ATC1441 to see if anything can be done further, or if I simply have a $35 beacon now. It's difficult to get this far and have to give up.

And a very huge THANK YOU to @Gordon and all other contributors here... I haven't had this much fun in tech in a long time (yes, a bit of pain and frustration too... all part of the process).

@Gordon, have you had anyone else express desire for a ROUND watch Espruino (I mean truly round, not Bangle 1: square in a round frame)? I could (easily) be in the minority, but having a more dressy Espruino has appeal. Just curious...

Thank you @Robin! I've only invested a little time so far, as I assumed that sample code I had would work! I have Espruino running fine: buzzer and button work (probably touch panel and accel too!) since it's a pinout identical to P8! So close....

The real work now begins... digesting the nuances of the ST7789.

That's what I tried (both Arduino & Espruino) with similar results. I was hoping the effect may have been something that looked familiar to you, to help me look in the right spot. I was assuming that this code WAS from the original firmware, but ATC mentioned he wasn't certain as there are two versions of the watch.

It was a long shot... thanks anyway.

@Gordon Thank you for that input.. that makes sense. I've tried toggling all the undocumented pins with no luck; it may be a setting in the init as well.

If I get it, I'll share.

work great as a sundial! So, sure... it's "fine!"

I guess this is really for @fanoush, but I'll welcome any input.

I've flashed Espruino to an SN80 (nrf52832, DaFit, 240x240 round ST7899). The pinouts are identical to the P8, so I used a prebuilt P8 (fanoush's espruino_2v08.5_p8_SDK12_SD30_SPIFLASH.z­ip) I used ATC's init code, replacing the default in the ST7789 Espruino module. I'm getting odd results. In the video, I start at reset(), then load the driver (sets up SPI, runs the init) then draw "Espruino" after 2 secs, then a white rectangle (full screen) after 2 seconds. you can see the draws happening, but everything is a vertical line. And more, in the still picture, you can see what happens after a minute, the screen dims in a doughnut shape! I have the ST7789V datasheet, so I'm prepared to do some homework, but any direction would be greatly appeciated!

(I checked in with ATC and he doesn't remember what he did exactly... there are two versions of the hardware so he's not sure if he's mixed them up. I also tried his code in ATCwatch and get the same result).

thanks to anyone for any help!

totally understand, and no rush! just curious. Who knows, future Bangles may need a shared SPI and use a _DSHARED_SPI flag. Anyway, nice work!

@jeffmer I am using your Espruino fork now with my Pinetime and am wondering if you have folded your SPI changes into Espruino master? They seem harmless and can even be #ifdef'd for specific devices. Any plan to merge?

@fanoush Ha, ha.. I was wondering if it could be done by the board file alone.. and now you've answered that! Going to try that, thanks.

I'd post this in a new question, but can't seem to find the new post button ???

Is there any way to set a pin high in the board definition file. The pinetime's main button (D13) will only work if D15 is pulled high. I can do this in code and it's fine, but I'd like it set up before we enter .boot code so it can trap button press early.

I'm not an EE, so sorry for the newbie questions: but how do I set a pin high in a build? Looks like pinetime has a button enable pin to set so the button pin itself works. can I do that in the board file?

Super newbie: is P0.01 map to D1 in Espruino? Are the pins mapped 1:1?

Thanks!

I am glad you guys are here to reality check me. I had built using DFU_UPDATE_BUILD=1 which yielded a much smaller hex (really app_hex) file. Removed that define... now have a real .hex file. Now Pinetime is visible... thank you!

I've just tried to build a minimal Espruino with only the BTN defined and used OpenOCD to flash to Pinetime. I'm not seeing anything in the Espruino web IDE. I did an nrf mass_erase to clear out Infinitime, then built both the bootloader (BOOTLOADER=1) and the board fw, programmed the bootloader (hex file) and board fw (first hex file, then bin file from zip). Am I missing a step?

Got it working on another linux instance, but hope to fix this eventually. Thanks all!
