WebOct 6, 2024 · TL/DR: you have to set 7th bit in DDRB to one. In AVR ports are configured by bits in two registers: DDRx and PORTx. When the corresponding bit in the DDRx register is set to one, the port is configured as output. And the corresponding bit in the PORTx register chooses which electrical level is output on the pin. If it is 0 then internal MOSFET ...

It's usually I2S, or something else with a monotonic frame clock so frequency response is guaranteed. Regardless, the DAC update rate is governed by SYNC/. The DAC will update 16 cycles after SYNC/ goes low. Looking at the data sheet, the data is sent to the DAC MSb first.

WebNow suppose that we have first set DDRB=1 as shown in the third row of Table 1. The DDRB register would ordinarily be set prior to reading or writing PortB. The MCU reads the DDRB register and sets the physical pin #12 as an output. Because the other bits in DDRB are zero, the remaining physical pins 13-19, which are named B1-B7, are all inputs.

Port registers allow for lower-level and faster manipulation of the i/o pins of the microcontroller on an Arduino board. The chips used on the Arduino board (the ATmega8 and ATmega168) have three ports: 1. B (digital pin 8 to 13) 2. C (analog input pins) 3.
