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.

Do you want to use the UART to print messages/log data over terminal on a PC?

Or do you want to implement UART over BLE ?
