Hi,
I just started to interface the lcd display with nrf51822 evaluation board. The display i'm using is, spi compatible, 18" tft (160x130) from tiny lcd. I took spi master...
Hi,
We are using the nRF905 device in an application where it needs to switch between auto-retransmitting and sending single packets, due to it communicating with several...
This is not a real question for support. It's more a success story i'd like to share with you!
Our company develops firmware for various customers on a lot of different...
Hi all,
What is the maximum data rate for the nRF24AP2 when using the Synchronous serial interface?
I cann't see it in the datasheet.
Is there anyone can answer me...
Hi,
In my design, there is a tag used by 24l01,It can transmit the temperature value.In the tag, the parameters are like this:
addrofch[0] = 0xe7;
addrofch[1] =...
We've been working on a product that utilizes a NRF51822 chip as well as WS2812B NeoPixels. Since there have been numerous posts about it here we've decided to release our...
I've recently discovered the power consumption issue with FreeRTOS and SDK12.3:
devzone.nordicsemi.com/.../
So, I am now using SDK12.3 with SDK13.1 FreeRTOS files.

I am using Nordic SDK to program an nRF51822 chip. I want to optimize power consumption as much as possible so I am looking at using the -march gcc flag. The problem is I...
I am using the ble_peripheral template that comes in Nordic SDK 8.1. I setup uart logging and also debugging with the following lines of code:
void assert_nrf_callback...
Hi, We are trying to connect a LED to one of the GPIO of nRF52840, we would like to know how to connect it. Connect it such that the nRF52 GPIO sink current or source current...
Hey, I am using WT51822-S4AT module and want the nrf51822 to connect to phone. I don't have nrf51-dk. I am using stm32f0-discovery kit. Can it be done using that kit? I searched...
Seems battery reads are not consistent in thngy52 2.1.0 software.
Observed a ~4% difference in the consequent battery reads. This difference is high (upto ~40%) if the thingy...
In the recent past, I used a SoC in which GPIOs could be configured as "open drain", that is in which there is an internal transistor where the SOURCE is grounded, the DRAIN...
Hey,
I'm using nRF as a SPI slave with a Raspberry Pi. I'm seeing that even at ~3MHz SPI frequency, my first byte transferred gets corrupted. I have a test setup where...
I am using nrf52 with s132 and armgcc
As I add functionality to the code I get to a stage where it fails. Linker runs OK but the result fails to execute.
The observable...
I am currently working on a BLE beacon project on nRF51822. Using SDK 12.3.0 and s130. The device has to advertise URL, advertising name and output power level. And these...
I am trying to control a current measurement chip (DDC114) that works with a protocol that is close (enough) to SPI. It has 2 channels, s.t. it can be read out and integrating...
I am attempting to run my first bit of code on my Nordic nRF52-DK and every time I have attempted to upload the code to the board, the board disconnects in the middle of the...
