I don't have one of these VGT6 boards. I do have a few VET6 ones. This might be a good starting point for creating your own board def: https://github.com/mcauser/BLACK_F407VE The VE has 512 Kbytes and the VG has 1 Mbyte flash. Other than that, pretty similar. See if you can grab a schematics pdf fro...

No mention of the Pyboard D-series on: http://docs.micropython.org
Anyone working on that?

The ST docs list the pyboard's STM32F405RGT6 temperature range as -40 to 85 deg C. https://www.st.com/content/st_com/en/products/microcontrollers-microprocessors/stm32-32-bit-arm-cortex-mcus/stm32-high-performance-mcus/stm32f4-series/stm32f405-415/stm32f405rg.html The 3 new Pyboard D-series, SF2W (S...

I’m guessing because it’s a 128x32, there is a different init command to set the row offset. Most other 128x32s are positioned half way down in the 128x64 buffer.

With all this talk of creating display drivers in C...
Can one written in C subclass the Framebuf?

Updated to pack 8 data bytes into 9 bytes, with a byte of DC bits.

On ESP8266, full screen writes (864 bytes) are now more than 2x faster, without writing all of those padding bits.

Nice work @fanoush!
I ordered 2x from GearBest. That promo code "MPOWDS-D6" saved me a few extra bucks. Thanks for that!

@Roberthh I tried squishing it like that, but couldn't get it working.

Edit: Tried again tonight and it worked this time!
Now I just need to figure out how to pack 1 extra bit before every 8th bit, efficiently.

I've been mucking around with this display and found the Nokia 5110 display to be significantly faster. Having to send the 9-bit SPI as 16 bytes means tons of wasted bytes being sent. 96 * 72 / 8 * 7 = 6048 extra padding bits for a full screen refresh. If I can figure out how to send multiple sequen...

Yes. Start here: http://docs.micropython.org/en/latest/e ... index.html
