: Because in most cases the status change of a GPIO triggers the application to perform some actions. In order to facilitate the NRF51 official to encapsulate the process into Gpiote, full name: The GPIO Tasks and Events (gpiote).From Gpio level changes to the process of generating interrupt events1. Gpiote OverviewNRF51 has 32 gpio above, because in most cases the state of the GPIO triggers the application to perform some actions. In order to facilit

Introduction and generation tool of the nRF51 DFU initialization package, nrf51dfuNRF51 DFU initialization package When upgrading data packets, before the application image is transmitted, You need to initialize the package in DFU to perform image security detection. This initialization package provides a security detection mechanism as part of the upgrade process. Therefore, the upgraded device can only receive compatible applications. The initializa

Report back with any complications.Ble_app_template_with_flash_operations.zipUpdate 27.3.2015 The example above is tested with SDK 6.1, Softdevice 7.0.0/7.1.0 and second revision nRF51 harware. It should also work with SDK 6.1, Softdevice 7.1.0, and third revision nRF51. For further compatibility of different SDKs and softdevices, and to see t

Objective:NRF51 can support 2.4G-based mutual communication, communication with NRF24LE1, communication with NRF24LU1, and communication with NRF24L01.First, nRF51822 based on 2.4G and nRF51822 communicationWhere nRF51 communicates with each other and is similar to the previous 51 operation Nrf24l01, it involves only a few core functions: Nrf_esb_init---Initialize an ESB Nrf_esb_enable---Enable ESB NRF_ESB_ADD_PACKET_

the Gpiote channel is configured to operate on a task pin, the outinit in the config[n] register determines the initial value of the pin. You can configure the Outinit to set the PIN initialization status to high or low.2.1.2 Port event Gpiote contains a port event in addition to 4 channels. The port event is triggered by multiple pins using the Gpio detect signal, and the rising edge on any of the pins in the port triggers the port event.You can set one or more Gpio detect to generate a port e

NRF52 series -- nRF52832 strikes, and nrf52nrf52832 strikesNRF52 series -- nRF52832 attack With decades of development in wireless technology, Nordic has launched the first μblue chip, nRF8001. Its low power consumption and other features attracted the attention of countless manufacturers at that time, and applied this product to multiple fields. After that, it launched the ultra-low power wireless SoC nRF51 series, taking advantage of its high integr

blindfolded) MBR ----> MBS ----> Bootloader ----> FirmwareThe MBR is part of the Softdevice. It Boots the CPU and jump to MBS. The MBR contains methods to start the Softdevice and can flash Softdevice and bootloader.The MBS handles the on/off button and comunicate the duration of the press to the bootloader so, the bootloader knows What to boot. The reason for the MBS are to allow updating the bootloader over the air while still have a write-protected piece of soft Ware that can start the STM32
