Hello, I've been working on porting a bit-banged control of a peripheral to use nRF51 SPI--which is just SPI rather than SPIM (therefore no DMA). Observe the SPICLK waveform...
Hi guys,
I am developing a project where I have a large group of NRF52 chips together in one room. In their normal state each chip is paired as a BLE peripheral device...
We are working on a NRF52 DK. In the data sheet of NRF52832, there is no mention of enhanced shock burst mode or dynamic payload or multiceiver. Do I need to refer additional...
we're using Mbed for NRF51822. our board using 2 GPIOs interrupt.
problem: the Rise edge did not generate the Interrupt event: set EVENTS_PORT.
I try uisng while, but...
Hello,
I will explain my setup:
I have 2 nRF51-DK each one of them connected via I2C and SPI to two different custom boards. One being the central(nrfA) and the other...
