The fastest is still the C native library, topping out at just under 42 MHz. Other languages and libraries are much slower, but the RPi.GPIO Python library stukk sees a 2.5x increase.

Yes, for most applications you really don’t need incredibly fast GPIO, but for the one time in ... scope revealed he was now toggling pins at 2.8 Megahertz, or just about a thousand times ...

Yes there are multiple variants of the System on Chip used in the newly released Raspberry Pi Pico 2. The RP2350A has support for only 30 GPIO pins while the RP2350B can support up to 48 GPIO.

The 1.2V GPIO library provides a bidirectional I/O driver for Parallel Trace Interface applications. This cell is compliant with version 2.0 of the the MIPI Specification for Parallel Trace ... The ...
