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 want to confirm two points in the PCB layout of nRF52:
In the data sheet and in the reference circuits section, there are no caps on pins 37 and 38 (QFN...
I made up a prototype board with BLE Nano2, connected via a JLink.
I'm using armgcc. JLink is needed to support RTT as I need the UART for another purpose.
My board file...
I'm upgrading an SDK13.1.0 project to SDK14.0.0. I'm using bonding and Peer Manager. nRF52832. Softdevice S132 5.0.0.
I no longer get any PM_EVT_PEER_DATA_UPDATE_SUCCEEDED...

Hi, I would like to control 2 LEDs independantly with the same server node. Should I try to [1] add a element with the same simple on/off model in that server node OR [2]...
Hi,
I'm running an ADC sampling every 8msec, sampling the output value of an op-amp as well as a reference voltage. I subtract the two in firmware. I was implementing the...
Hello,
I am using SPI interface to communicate with a sensor BMI160, looking into the driver for BMI160 I can see how the low level functions for reading/writting are used...
