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...

Hello,
I've checked the timing diagrams for the CE and IRQ on the datasheet but I would like to know if anyone has actually tested them with an oscilloscope? If yes could...
I am using SDK 11.0.0 on a nrf52832, with FreeRTOS and SD132 2.0.0. I configure the FreeRTOS port so that it uses RTC1 as SysTick. Depending on some compilation macros, my...
Assuming that all peripherals that require the high frequency clock are disabled / turned off / stopped, how long does the HFINT oscillator run after calling __WFI()?
And...
What's the delay from setting the Start / Stop task in an RTC module to when the RTC actually starts or stops? Is it less than 1 clock cycle on the CPU (15ns)? More than one...
Hi, I am using the nrf52 dk to sample two analog inputs through PPI.
My question is if I can use different bit resolutions for each analog input?

Hello !
I have a problem with my program (on a nRF52 board) : when I send a value to the board via BLE, it seems that my static variables are reset.
I noticed that, because...
I need to store data in some moments and if something happen i have to read those data, i have to do a log events.
