Hi,
I have a code programming the nRF51422 development board to write to a Sharp Memory 96x96 pixel LCD screen using SPI.
Currently the code writes two numbers and a...
I've modified the ble_app_uart example by adding GPIOTE so that the transmitter sends a character to the receiver when a GPIO pin is toggled. This part is working well.

Hi,
I am working on my hardware product having nRF-51422 chipset. I just came to know from forum post that
nRF-52 chips will get arduino IDE support as standalone. I want...
I have 3 inputs I need to sample every n minutes. I have an n-minute timer that can kick off the first one, but I need to run the second and third samplings in succession...
We are creating our own dev board.
What pcb parameters were used for the PCA10004-nRFgo PCB antenna radio module 2.0?
1.6mm?
1oz Cu?
impedance control?
I have not...
Hello,
We want to use the J-Link Needle Adapter for nRF51822
The attached (capture.jpg) is the pinout from the J-Link Needle Adapter datasheet.
the attached (capture2...
Hi,
I have a wired problem with the nrf51422,
I'm loading the code using the J-link into my board or the evaluation board (PCA10007) that I have, the code runs perfect...
Hi all, I met a problem with measuring lithium battery voltage. I used 1Mohm and 250Kohm divided voltage, and used the internal VBG voltage as reference, and used ADC0 as...
I'm using a nRF51844
I'm writing my own ADC reading routines because I can't find any examples, but I know how to code so that's not a problem. I just want to confirm something...
Hi,
does a code example or app-note exists that describes how to configure the SPI peripheral to use an ISR to transmit data to a SPI slave?
Thank you in advance!
Dear
Do you know of a "present" /not present" low cost 2.4 GHz RFID chip for static asset monitoring in WiFi environment. compatible with, and actively associates with 802...
I am trying to hook up nRF8001 to TI MSP430F663x via nRF2740 module.
All inputs seems to be controlled properly.
Once I release the nRF8001 RESET line, RDYN goes low...
Hi,
I have a simple battery powered remote control device with a NRF51822 and using the Gazelle protocol for communication with the host.
To save battery the MCU goes...
The last few weeks I'm working with the nRF51422 and run in to several TWI/I2C issues. All of them I could solve except an issue with a SAA1064 7segment display driver from...
We have a custom board with nFR51422. Of the first 4 prototypes only one works correctly. This indicates that the PCB is ok. One difference is the chip marking. The working...
My test: PCA10000+Master Control Panel(3.4.0.8098) as central role, conninterval=20ms
nRF51822+softdevice(5.0) as peripheral role, conninterval=10ms
then sd_ble_gap_conn_param_update...
Hi all,
