Macro Definition Documentation

◆ __IO

#define __IO volatile

LPC2387 MCU defines.

Definition at line 33 of file periph_cpu.h.

◆ DAC_NUMOF

#define DAC_NUMOF (1U)

DAC configuration, valid for all boards using this CPU.

lpc23xx has a fixed mapping of DAC pins and a fixed number of DAC channels, so this DAC configuration is valid for all boards using this CPU. No need for any board specific configuration.

The DAC of the lpc23xx is mapped to the following fixed pin:
