Macro Definition Documentation
◆ 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:
- line 0 (ch0): P0.26

Function Documentation
◆ gpio_init_mux()
| int gpio_init_mux | ( | unsigned | pin, |
| unsigned | mux | ||
| ) |
Set up alternate function (PMUX setting) for a PORT pin.
- Parameters
-
[in] pin Pin to set the multiplexing for [in] mux Mux value
