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, recently I'm looking at some computer architecture books.
So my question could be easy or silly.
I tried to search more but I couldn't find many.
The nRF51822...
Since the SoftDevice uses Timer0, am I correct in assuming that the maximum number of PWM channels for nRF51-DK with SoftDevice running is 4? (Two each on Timer1 and Timer2...
Hi Expert,
At my nRF51 platform, I opened two GPIOTE users one of which is used to handle an external sensor interrupt. After invoking app_gpiote_user_register(&sensor_gpiote_user_id...
I am seeing some very strange behavior when using an ANT channel with the sd_ant_acknowledge_message_tx call to guarantee message deliveries between a master and slave.
