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. 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. impulsivity define
