Nice to know. Thanks!
I haven't used RPi at all, since when I
looked at it some years ago the SOC technical information was secret. Contrast the
BeagleBone, for which there is a 5000 page manual.
The Pico is quite different. They use their own chip for the Pico, the RP2040.
There is a 637 page manual https://datasheets.raspberrypi.org/rp2040/rp2040-datasheet.pdf
Unlike the other Rpi this is more like the STM32 chips
where you develop C/C++ or Python to run directly on the bare metal. No Linux involved.
That makes it like Arduino. Time for some more studying...
The early Rpi used Broadcom chips. And like most
Broadcom stuff you almost needed signing a NDA to get a glance of the pinout of the chip.
Exactly. Broadcom had all sorts of strange notions. The BBB uses a TI chip, which was
always fully documented.
