Webusing this, I managed to speed up my code by a factor of three. It is not as dramatic as for the AVR chips, since the digitalWrite function is much more simple for the ESP8266. Edit … WebMay 5, 2024 · Short answer: yes, easily. Slightly longer answer: 125 IOs / second * 20 = 2500 / second. A standard Arduino runs at 16 Mhz, which means it has 6400 clock cycles to do what you need. Even the (relatively) slow digitalWrite () command takes only about 17 clock cycles, leaving you lots of time to do other stuff.

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.

WebHow do microcontrollers (stm32) dynamically set the slew rate on GPIO outputs? I’ve read in the data sheet, and seen in CubeIDE, that I can change the GPIO output speed by setting two bits of a register.
