Can anyone give me a tip on porting the code below, which works great in sdk12, to sdk14? I'm using the nrf52832 and the ble_app_hids_keyboard example and need to get a real...
Hi, I'm kind of a newbie, haven't had much experience with embedded outside of arduinos etc.
So I started to look at this: https://learn.sparkfun.com/tutorials/nrf52832...
for sdk15.0, SES,
is the twi_scanner example known to work with nrf52810?
getting errors,
undefined reference to nrfx_twim_init, nrfx_twim_enable, nrfx_twim_xfer
Hi,
I am studying the GPIOTE example from SDK 14. I did some modification adding other led and doing the leds blinking in differents times (LED1 blink each 1 sec and LED2...
Hi,
The nRF52832 does not support Long Range and i was wondering if the use of "RADIO_MODE_NRF_250KBIT" would increase the range. My application is a mesh network.
Do...
Hello Everyone,
I am using nrf51822 with S130.
Currently I am using arduino following this repo to program nrf51822 and its working fine. However, I want to shift to keil...
Hi there
For test purposes, I first implemented a simple serial reading & parsing function in polling mode of a gps device (sending @ 1 Hz).
Everything works fine when...
Hello,
i am evaluating the nRF52840 on the nRF52840-Preview-DK. I have connected an ADC to the devkit via SPI and my code reads data from the ADC via GPIOTE, PPI and SPIM...
We've got two SPI slaves that we need to talk to with the 52840 (PCA10056 dev kit for now) using SPI Manager. In the initialization of these devices, I'd like to use nrf_spi_mngr_perform...
