DAC (Digital to Analogue Conversion) allows you to set a 8 or 12 bit digital value that is converted to an analogue value. MCU’s with these capabilities usually only have two pin’s capable of this.
| Init |
Initialize and wire the DAC. Set buffer size, pin and output frequency. |
| writeAnalogue |
Write a single analogue value either directly to the port or to an output buffer. To ignore output buffer just set it to zero in Init(). |
