turning off qdec led

[archangel689]

In the nrf52 specification:

"The Phase A, Phase B, and LED signals are mapped to physical pins according to the configuration specified in the PSEL.A, PSEL.B, and PSEL.LED registers respectively. If the CONNECT field value 'Disconnected' is specified in any of these registers, the associated signal will not be connected to any physical pin."

There doesn't seem to be an obvious wrapper for this in the sdk. How do I access the PSEL.LED connect field to disable the LED?

Thank you

You can set the pin to 0xFFFFFFFF.

When using the default configuration (nrf_drv_qdec_init(NULL, qdec_event_handler)) you can set the default pin in nrf_drv_config.h:

#define QDEC_CONFIG_PIO_LED 0xFFFFFFFF

When using your own config:

nrf_drv_qdec_config_t qdec_config;
qdec_config.pselled = 0xFFFFFFFF;
...
nrf_drv_qdec_init(&qdec_config, qdec_event_handler)
