Hello,
I am able to build the lpuart sample in hardware folder for nrf9160dk_nrf9160_ns but not for circuitdojo_feather_nrf9160_ns. Is possible to port to feather?
Also, I am would like to use UART1 and UART2 instead LPUART. Is the same thing, i.e. UART1 and UART2 are LPUART?
Thanks.
vinifr What error do you get when you build for circuitdojo_feather_nrf9160_ns ?
vinifr you need another device that is capable of using the same driver on the other side. Here’s an example of how I use it with doing HCI UART with a nRF52840:
nRF91 Overlay:
/ {
chosen {
zephyr,bt-uart=&lpuart;
};
nrf52840_reset: gpio-reset {
compatible = "nordic,nrf52840-reset";
status = "okay";
gpios = <&gpio0 17 GPIO_ACTIVE_LOW>;
};
};
&uart0 {
current-speed = <1000000>;
status = "okay";
tx-pin = <21>;
rx-pin = <22>;
/delete-property/ rts-pin;
/delete-property/ cts-pin;
/delete-property/ hw-flow-control;
lpuart: nrf-sw-lpuart {
compatible = "nordic,nrf-sw-lpuart";
status = "okay";
label = "LPUART";
req-pin = <15>;
rdy-pin = <19>;
};
};
&gpiote {
interrupts = <49 NRF_DEFAULT_IRQ_PRIORITY>;
};Here’s what it looks like on the other side.
nRF52840 Overlay:
&uart0{
current-speed = <1000000>;
status = "okay";
tx-pin = <17>;
rx-pin = <15>;
/delete-property/ rts-pin;
/delete-property/ cts-pin;
/delete-property/ hw-flow-control;
lpuart: nrf-sw-lpuart {
compatible = "nordic,nrf-sw-lpuart";
status = "okay";
label = "LPUART";
req-pin = <13>;
rdy-pin = <12>;
};
};
/ {
chosen {
zephyr,bt-c2h-uart=&lpuart;
};
};
&gpiote {
interrupts = <6 NRF_DEFAULT_IRQ_PRIORITY>;
};Also some important configurations:
CONFIG_UART_0_ASYNC=y
CONFIG_UART_0_INTERRUPT_DRIVEN=n
CONFIG_UART_0_NRF_HW_ASYNC=y
CONFIG_UART_0_NRF_HW_ASYNC_TIMER=1
CONFIG_NRF_SW_LPUART=y
CONFIG_NRF_SW_LPUART_INT_DRIVEN=yThe above will be slightly different depending on which UART you’re using.
Also, I am would like to use UART1 and UART2 instead LPUART. Is the same thing, i.e. UART1 and UART2 are LPUART?
That’s totally fine too. Simply map the UART interface to the pins you want to use and make sure it’s enabled. LPUART is optional and not defined by default AFAIK.
