Connecting the Pervasive Displays EXT3 to the Raspberry Pi Pico RP2040

5/23/2021

 
I started investigating the Raspberry Pi Pico RP2040 with the newly released Arduino mbed OS RP2040 boards core version 2.1.0.

The issues I experienced with SPI on the previous 2.0.0 version seem to be gone.

With just setting CONFIGURATION_OPTION to CONFIGURATION_EXT3_PICO_ARDUINO, the same sketch drives the Pervasive Displays e-ink screens throught the EXT3 extension board.

Leaving Apple for Linux

5/23/2021

 
In 2006, I switched from Windows to Apple. In 2021, I'm switching again, this time from Apple to Linux. 

The change was prompted by the repeated hardware failures I've experienced with the last two MacBooks (with an MTBF of 4 months) and the disastrous Apple customer service, resulting in a very high total cost of ownership (TCO of USD2,737 per year).

The switch to Linux was surprisingly quick and easy.

I chose Debian with default Gnome, mainly due to my prior experience on the Raspberry Pi boards. Gnome offers a clean interface with few distractions.

As IDE, I picked the excellent Visual Studio Code and kept the GCC tool-chain.

Adapting embedXcode to Linux required very few changes, thanks to the technologies it relies on. As a benefit, debugging is now internal.
