Pro tip: The simplest way to be a "10x" programmer for RPI projects - ditch the RPI (any/all) and develop your software in a Debian VM running on an Apple Silicon Mac.

github.com/bitbank2/Fas... New - I shared a low power eink clock project that updates every minute (no flickering). It pulls the correct time/date from NTP every day and a half and uses the ESP32's RTC to keep the time. It can last for months on a small battery using ESP32's deep sleep.

In today's mail - A fragile piece of glass masquerading as a retail product. The Waveshare 7.8" parallel Eink panel with IT8951 RPI HAT. Soon to be supported by my FastEPD library (on Linux, Arduino and esp-idf).

Some new devices landed on my desk over the past few days. Waveshare AMOLED 2.16 ESP32-S3 (480x480), M5 Paper Color (ESP32-S3 w/ 4" Spectra6), NM-CYD-C5 (not shown) and the GKD Pixel2 (nostalgia machine). Each quite impressive in their own way. I added them to my display libraries (not the GKDP2😜)

Parallel GPIO on the original RPI 1 and ZeroW can do interesting things too (e.g. drive QSPI displays), but the single core Armv6 CPU is too slow for modern projects of any type. RPI Z2W is the minimum useful board. This GIF player runs at 50fps (360x360 pixels) on the Z2W - much slower on the ZW.

I just added support for the LilyGo T-Deck Pro to bb_epaper (github.com/bitbank2/bb_...). It's a named device, so the GPIO connections and panel type are under a single name (EPD_LILYGO_T_DECK_PRO). N.B. Don't use DEEP_SLEEP because the reset line is NOT connected to an ESP32 GPIO.

Finally got some copper heat sinks to test the Radxa Cubie A7z. It still runs too hot, but is relatively stable now. It's basically a RPI0 sized RPI5. It runs code 2-3x faster than an RPI4. Too small an area to dissipate that much heat. Need to find a way to lower the CPU clock speed.
