I'm using SDK 16.0 with nrf52832, for storing some information iam using flash storage, during initialization, we are giving a starting and ending address to flash...
Hi friend,
We have a project with BLE connection. It sends out the Manchester data and the data modulates with 125KHz. Can we use PWM to do that? Will the data format be...
My platform is SDK16 with softdevice, MCU nRF52840. I used 2 pin to generate PWM at 125KHz for Manchester coding. I want them are at different pin polarity. For example, if...
Hi all,
I am working with the nRF52 dev kit and the ecg sensor MAX30003. Using MBED to develop firmware.
I am using this library and the example code from maxim ( https...
