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...

I had a mbed firmware running on a ST Nucleo 64 that periodically query a sensor for data. It only use the I2C, a button interrupt and a LED for heartbeat. I ported it to...
Hi,
I want to know that if the TWI easyDMA in nRF52 can help in achieving this task:
we want to read from TWI each 10msec based on a timer interrupt and write...
Hello:
I have detected a problem with a timer on my program.
I can solve it, but I would like to understand what is happening exactly.
My program starts to scan BLE signal...

Hi,
I'm trying to implement a HID gamepad on nRF52832. Here is my situation:
nRF is receiving frame over UART from master uC every 15 ms. Frame is being converted and...
I was trying to track down high, approx. 6mA, processor current consumption and I have found high current consumption if the FPU executes a divide by 0. If I comment out the...
When I start the "ble-sniffer_win_1.0.1_1111_Sniffer.exe" program I get this screenshot:
The port was found correctly (COM4) but I see no devices found.
Am I missing...
Which is more lower power consumption,system off mode or system reset (according to nReset/SWDIO pin Lo) when we don't use nRF51822 for a long time ?
Our products have...
Hello,
I have this code
if (NRF_SUCCESS!=nrf_drv_twi_tx(&m_twi,devAddr,®Addr,1,true))
