What is the maximum and minimum frequency of the PWM signal/square wave that can be measured on the NRF 52DK board I'm using NRF 52832.
Also, what is the max and min "pulse...
Hello,
I have found similar questions on transmitting multiple bytes over SPI, but I am still not sure how to do it. I want to communicate with a driver which needs to be...
Hi,
I found the 'Solar Sensor Beacon' example from
https://github.com/NordicPlayground/solar_sensor_beacon .
There, I found that no softdevice initialisation (nrf_sdh_ble_enable...
I am working through the nordic sdk 8.1 peripheral heart rate monitor example. I am wondering what RR is? I can't figure out what it stands for or what the purpose of it is...
Hi,
In my current project I have indicating LEDs connected via TWI bus. In this case, I can't use BSP_LED_0/BSP_LED_1 outputs to indicate states as it implemented in nrf_ble_dfu...
Hello, I recently use nrf52832 to make a wireless sensor network of BLE concurrently with NRF_ESB.
During development, I use only 2 sensor. Both sensors are connected to...
