Hi, I am using urf52832 ( also have 52833 dk).
I am trying to use another pin us uart, which tx is 29 rx is 30 define in project_pinconfig.h.
But I can't see any uart output.
#include "project_pinconfig.h"
&pinctrl {
uart0_default: uart0_default {
group1 {
psels = <NRF_PSEL(UART_TX, 0, TX)>,
<NRF_PSEL(UART_RX, 0, RX)>;
};
};
uart0_sleep: uart0_sleep {
group1 {
psels = <NRF_PSEL(UART_TX, 0, TX)>,
<NRF_PSEL(UART_RX, 0, RX)>;
low-power-enable;
};
};
spi0_default: spi0_default {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, SPI0_SCLK)>,
<NRF_PSEL(SPIM_MOSI, 0, W0)>;
// <NRF_PSEL(SPIM_MISO, 0, 28)>;
};
};
spi0_sleep: spi0_sleep {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, SPI0_SCLK)>,
<NRF_PSEL(SPIM_MOSI, 0, W0)>;
//<NRF_PSEL(SPIM_MISO, 0, 28)>;
low-power-enable;
};
};
spi1_default: spi1_default {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, SPI1_SCLK)>,
<NRF_PSEL(SPIM_MOSI, 0, WS2812_L)>;
// <NRF_PSEL(SPIM_MISO, 0, 29)>;
};
};
spi1_sleep: spi1_sleep {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, SPI1_SCLK)>,
<NRF_PSEL(SPIM_MOSI, 0, WS2812_L)>;
// <NRF_PSEL(SPIM_MISO, 0, 29)>;
low-power-enable;
};
};
spi2_default: spi2_default {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, SPI2_SCLK)>,
<NRF_PSEL(SPIM_MOSI, 0, WS2812_R)>;
//<NRF_PSEL(SPIM_MISO, 0, 24)>;
};
};
spi2_sleep: spi2_sleep {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, SPI2_SCLK)>,
<NRF_PSEL(SPIM_MOSI, 0, WS2812_R)>;
//<NRF_PSEL(SPIM_MISO, 0, 24)>;
low-power-enable;
};
};
};
This issue can be recurrence on 52833dk by changing tx rx to 29 30.
