WebThe GPIO pins cannot handle such speeds. I've found that the max read speed of the GPIO header is about 1kHz. The max the UART can handle is about 1Mbaud for stable communication and 4Mbaud is the max the kernel can handle. Anything higher than 1Mbaud requires USB or Ethernet. WebJan 3, 2024 · It has a risetime of 1.5ns on a 10pF VDD = 2.7-3.6V GPIO set to fastest speed. It's designed to run SPI or memory buses at up to 100MHz, which is still a period time of 10ns, so an eternity relatively speaking. I don't think the RP2040 stretches this far. 10pF requires also quite careful design.

WebIt is slightly different than for the AVR chips. There is one register for setting the pins to HIGH and another one to set the pins to low. Setting the pin HIGH: GPOS = (1 << PIN_OUT); Setting the pin LOW: GPOC = (1 << PIN_OUT); using this, I managed to speed up my code by a factor of three.
