I have asked a similar question in the Nordic support forum but thought I would float this question here as well since this probably more of a design/implementation question than a Nordic specific question. Initial architecture support of the NRF52 including UART, Timer, and GPIOs was contributed by Janne Rosberg in NuttX-7. On the nRF52_DK, I2C_SDA0 and I2C_SCL0 are mapped to pins 26 and 27 (p26, p27): nRF52 and twi dma, or any mcu with dma- if you give the compiler information about the buffer you use for dma, in certain conditions it may think it knows all about that buffer- bool isReady () { uint8_t buffer = { 0,0 }; //init buffer for some reason This tutorial is also a part of my on going series for beginners and in this tutorial we will learn how to program I2C or TWI in nrf5 sdk using nrf52832 or n The nRF52 Series SoCs are all Bluetooth 5. nRF52832のADC.
