WebJul 28, 2016 · For example for a 8 bit PIC microchip device, the best you could do for a 'digital read and test of a bit' is using the single instruction 'btfsc' which reads bit test file skip next line if clear. If you were to read the port and compare it to a literal byte, you'd be doing more assembly i.e. movlw 0x20. andwf PINE,0. WebPort manipulation To efficiently send pixel bytes to our display we used the port C of our Arduino Micro. However port manipulation on Teensy 3.2 is quite different from Arduino Micro. To find out more I suggest you search its manual for GPIO. As seen below we used the port D of our Teensy 3.2. Using GPIOD_PDOR to write our byte.
WebDirect port manipulation will be significantly faster than using digitalWrite, but for most things (like controlling a motor) digitalWrite is plenty fast enough. Port manipulation is harder to set up, harder to understand, and is not portable across devices (the port assignments are different for different Arduino models.) – WebApr 7, 2024 · Converting Arduino port manipulation to ESP32. I have some code written for Arduino that I am trying to convert to run on my ESP32. It uses direct port manipulation (something I'm not too familiar with). As I understand it I should be using GPIO_OUT_REG and GPIO_OUT1_REG. My issue is I don't entirely understand what the Arduino code is doing.
