Arduino camera screen6/20/2023 RW goes to Pin 7, RS to Pin 6, E to Pin 5. I would recommend connecting D0 through D3 to Digital Pins 8 through 11 for the first four bits (meaning they'll go to bits 3 to 0 of Port B), and D4 through D7 to Analog Pins 0 To 3 (meaning they'll go to bits 3 to 0 of Port C). Since you need the RX and TX lines (Digital pin 0 and 1) for your serial communication, you will have to split the signal onto two registers. PORTC = Analog Input 0 through 5, reset pin.PORTB = Digital Pins 8 through 13 plus the crystal pins.#include "soc/rtc_cntl_reg.I would recommend ditching the the digitalRead in this case - it is performed sequentially, and is rather slow.Īs you only need to read 8 input lines, consider using Port register: The Arduino Uno comes with a total of three Ports which "hold" all of the I/O pins. #include "soc/soc.h" //disable brownout problems The above copyright notice and this permission notice shall be included in allĬopies or substantial portions of the Software.
