The following commit(s) were added to refs/heads/master by this push: new 1975e9eba bsp/pca100121: Init on board pins 1975e9eba is described below commit 1975e9eba5d78ebac9af19ebf5204cf174a63169 Author: Jerzy Kasenberg <jerzy.kasenb...@codecoup.pl> AuthorDate: Wed Oct 5 10:06:15 2022 +0200 bsp/pca100121: Init on board pins SD card and CS47L63 codec share SPI this make sure that both CS pins are high at start so unused peripheral does not interfere with used one. CS47L63 is kept in reset till it's used. CS47L63 on board is used instead of one possibly connected to external connector. --- hw/bsp/nordic_pca10121/include/bsp/bsp.h | 10 ++++++++++ hw/bsp/nordic_pca10121/src/hal_bsp.c | 16 ++++++++++++++++ 2 files changed, 26 insertions(+) diff --git a/hw/bsp/nordic_pca10121/include/bsp/bsp.h b/hw/bsp/nordic_pca10121/include/bsp/bsp.h index 2530211cf..baf59b2fa 100644 --- a/hw/bsp/nordic_pca10121/include/bsp/bsp.h +++ b/hw/bsp/nordic_pca10121/include/bsp/bsp.h @@ -55,6 +55,9 @@ extern uint8_t _ram_start; #define BUTTON_3 4 #define BUTTON_4 6 #define BUTTON_5 5 +#define BUTTON_VOL_DOWN BUTTON_1 +#define BUTTON_VOL_UP BUTTON_2 +#define BUTTON_PLAY BUTTON_3 /* Arduino pins */ #define ARDUINO_PIN_D0 41 @@ -88,6 +91,13 @@ extern uint8_t _ram_start; #define ARDUINO_PIN_MOSI ARDUINO_PIN_D11 #define ARDUINO_PIN_MISO ARDUINO_PIN_D12 +/* Other on board pin selection */ + +#define PCA100121_SDCARD_CS_PIN 11 +#define PCA100121_CS47L63_CS_PIN 17 +#define PCA100121_CS47L63_RESET_PIN 18 +#define PCA100121_HW_CODEC_ON_BOARD_PIN 21 + #ifdef __cplusplus } #endif diff --git a/hw/bsp/nordic_pca10121/src/hal_bsp.c b/hw/bsp/nordic_pca10121/src/hal_bsp.c index c23347f76..68a005417 100644 --- a/hw/bsp/nordic_pca10121/src/hal_bsp.c +++ b/hw/bsp/nordic_pca10121/src/hal_bsp.c @@ -29,6 +29,7 @@ #include <mcu/nrf5340_hal.h> #include <mcu/nrf5340_periph.h> #include <bsp/bsp.h> +#include "hal/hal_gpio.h" /* * What memory to include in coredump. @@ -96,6 +97,21 @@ hal_bsp_init(void) /* Make sure system clocks have started */ hal_system_clock_start(); + /* SDCard CS, (active low), default to 1 */ + hal_gpio_init_out(PCA100121_SDCARD_CS_PIN, 1); + + /* CS47L63 CS, (active low), default to 1 */ + hal_gpio_init_out(PCA100121_CS47L63_CS_PIN, 1); + + /* CS47L63 Reset pin, keep low at start */ + hal_gpio_init_out(PCA100121_CS47L63_RESET_PIN, 0); + + /* Select HW codec: + * 0 - on board HW codec + * 1 - pins routed to external header + */ + hal_gpio_init_out(PCA100121_HW_CODEC_ON_BOARD_PIN, 0); + /* Create all available nRF5340 peripherals */ nrf5340_periph_create(); }
