Hi everyone,
I'm doing my first project with ESP32 using the Arduino IDE.
I'm trying with ESP32 to see if I can get a better result than the arduino boards.
I connected some parallel DACs to the board and I have a series of int values to execute in sequence, with arduino I used the registers of the gates by directly writing the value in it, obtaining the consequent binary decoding on the pins, can you tell me what are the instructions to execute the same command with ESP32? I haven't found much online.
Thank you
Simone.

Re: write values directly to ports
You should be able to write to the GPIO_OUT_REG and/or GPIO_OUT1_REG registers directly (after configuring the GPIOs as needed).
You can look at the code of e.g. gpio_ll_set_level(...). Notice how some registers need special treatment for reads or writes to work.
