Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hi,
I was reading the procedure to prepare the NRF52 DK board for current measuring and some questions came into my mind. I understand we have to open the P22 so we interrupt...
I have set up raspberry pi 3 as a border router and programmed the the nrf51422 using the iot_ipv6_coap_server_pca10028 and could successfully switch on and off led3 and led4...

Hello!
Does anyone know what's the maximum frequency for SPI (SCLK) for nRF52832 or SDK 12.1? I see following code in nrf_drv_spi.h:
typedef enum
{
NRF_DRV_SPI_FREQ_125K...
Can someone tell me how the DETECT signal works in the nRF52840?
This version of the nrf52 has 2 GPIO ports.
Does that mean there are 2 DETECT signals? or is there still...
Hello, I'm using the nrf UART 2.0 app with nrf51822 and I'm wondering how a line of characters is sent using this app. For example if I write 'abcdefg' does the BLE receive...

I have verified that I am compiling against the correct header files. This service number for...
Hi, even if I set hal_nrf_enable_ack_payload(false) on the sender (and receiver), the receiver still sends back an ACK which i can detect in the NRF_ISR(). is this normal...
Hello,
I have a pca10028 and I am wondering if I can use it also to flash nrf52 boards.
I quickly tried with rknrfgo on mac to wipe a custom board based on nRF52832 and...
Hello.
I decided to use an external solution for RTC.
Sometimes the RTC chip offers an buffered 32.768KHz output.
Can I use this output to supply the 32.768KHz to the nRF52832...

Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
