WebThe pin is high or low, depending on if a 1 or 0 was written to each bit. Port B is associated with eight physical pins on the ATmega328. The name of each bit is an abbreviation of the port and bit position. We have bits 0-7 or PB0 thru PB7. (Counting always starts with zero.) Bits PB0 thru PB5 are the Arduino digital pins 8-13.

WebGPIO Summary. The ESP32-S3 chip features 45 physical GPIO pins (GPIO0 ~ GPIO21 and GPIO26 ~ GPIO48). Each pin can be used as a general-purpose I/O, or be connected to an internal peripheral signal. Through GPIO matrix, IO MUX, and RTC IO MUX, peripheral input signals can be from any GPIO pin, and peripheral output signals can be routed to … WebThe application is a simple function that either sets the specified PMOD I/O pin high/low or it applies a user-specified number as a bit mask to all 8 I/O PMOD pins, then it returns the bit mask of the 8 PMOD I/O pins current status.

WebMay 5, 2024 · The closest I've been able to do on the 328P chip is to use the upper four bits of port D, pins 4 - 7, for the high nibble and the lower four bits of port B, pins 8 - 11, as the low nibble. By reading each port with a mask and adding them together, you will get one byte. If you need to use SPI then use port C, pins A0 - A3, for the low nibble.
