Hi, i'm using SPI to transfer data divided into packets of 24 bit from NRF51 to a DAC. The function that allows to send data is: spi_master_send_recv(SPI_MASTER_1, data_vector_tx, 3, data_vector_rx, 0); Analyzing the MOSI signal and the clock signal…

I have a few questions (using nRF51 DK and/or external nRF51822) I use an analog pin to measure the voltage of a capacitor of an analog circuit. From time to time, I would like to discharge the capacitor by setting the analog pin to the ground…

I am working on a device which also needs to give audio feedback to the user. The app on the mobile phone needs to send a wav (or similar) file (mono, speech) to the device and the device needs to play it through a small speaker. Is this possible…

Hi, I'm working on a project where I'm trying to make an nRF51822 play a basic sound (such as a beep). Is there a recommended DAC that should be used with this particular SoC? Does anyone know in general how to get the chip to play sound? Also- I'm…
