Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

Hi!
I am using nRF51 SDK v6.10. I try to analysis the "spi_master_example". Source codes is
working well. But I couldn't understand how the "spi_master_send_recv_irq(...
I have an android application, which one can set and unset the LEDs of my nRF51422 EK. But sometimes when I click to fast the command will not be send. So I would like to...
Hello,
I want to know if it is possible to configure a button to act with different Detection delay.
In other words I want to have a single button to be able to trigger...
Do we have KiCad version of nRF51822 QFN48 reference design? We looking at open source toolkits, including Eclipse, so KiCad comes into picture.
Thank you in advance!
The test code:
int main(void)
{
sd_softdevice_enable(NRF_CLOCK_LFCLKSRC_RC_250_PPM_250MS_CALIBRATION, softdevice_assertion_handle);
temp_init();
unsigned int aaa...
I have a follow-up to this question: devzone.nordicsemi.com/.../
We are interested in dynamically changing the supply voltage because our space-constrained design requires...
Hi,
For my custom PCB, I am using the PCA10004 as reference in order to determine if the maximum possible range has been achieved. However, I am seeing only about 20 feet...
Hello I'v just ordered a NRF51-DK kit.
I'm looking at the different tool chain. In my application speed is critical 16Mhz is actually bearly enough, so my question is:...
I have a USB dongle with an nRF24LU1p that has a few SPI pins but is missing the RESET pin. I would like to be able to program it via SPI but the SPI programming protocol...

Hi,
Access to the UART hangs the execution of the experimental_ble_app_uart_s110_pca10028 example.
The phenomen occures In the file simple_uart.c when checking for the...
This may not be a major disaster,but it bothers me:
I have written an application to read data from an ADXL345 accelerometer (using SPI) and print out the data on a console...
Good morning,
i still couldnt find out if it is possible or recommended to use the PPI together with the s110. i checked the example in the sdk documentation but it was...
I have an in memory log variable that I write to on various BLE and device manager events. If there is ever a serious error, my implementation of app_error_handler() now takes...
Hi,
I have programmed the radio_test_example to target having nrf51822 qfacaa chip. I have changed the UART pins as per the custom board.
It's working fine but showing...
