how to get data ADXL345 using nRF51822 via arduino IDE and mbed compiler

[mantap]

I've already tried before using ADXL345 using nRF51822 using mbed compiler this is the link.. os.mbed.com/.../

but that program can't get ADXL345 data, just UART nRF51. I've tried using nrf51822 too with Arduino with this method.. github.com/.../arduino-nRF5

that problem appear again, using Arduino compiler can't advertise/beaconing UART via nRF UART mobile phone. so please help me to fix both problem..

• fix program using mbed compiler, to read ADXL345 data using nRF51822
• fix program using Arduino compiler to flashing the nRF51822 using stlink v2

Hi,

You can't use UART for this. The digital output data from the ADXL345 is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.

AnalogDevices have an mbed library for the ADXL362, which have a similar register map as the ADXL345, you can take a look at the library here. You can also take a look at this mbed code here.

well, if using nRF51 SDK, how to use it? I have been study stm32 cubeMX to code HAL_Driver in system workbench (AC6) and keil. So are there any nRF51 same procedure how build firmware easily, same coding how to build program for user which is doesn't have many experience using that Bluetooth Low Energy... Please help me to get how data communicate ADXL345 using SPI or I2C that conncected to nRF51822 module that have ARM cortex M0. we are so hardly developing your product. please make it easier to learn...
