ADXL 345 Tutorial

Hello all, this tutorial goes to a fellow named Emil who helped me with this project.Number 1_ Make sure you set up the terminal viewer For debugging with real.You need it to see the values coming outta your ADXL 345 chip in the case you don't have an osciliscope or a Logical unit. Click here Number 2_ How does the ADXL 345 work?ADXL 345 datasheet says there are two ways you could read x, y and z information from the register. 1 I call it serial mode in which you send (0x80| 0x40 | 0x31) to the ADXL345's ...

Hi Guys, Thanks for your precious time and insight. Let me try to explain what we did,After assembling the board, we do a bare board test where we check all impedance's including those across VDD, AVDD and capacitors provided for the Chips internal voltage regulators. 1) In all instance across four boards we have tested(bare boards before power up) , impedance were above 100K. 2) Then we Power up the board and test voltages. The board is powered up using a coin cell battery or a 3V supply. Measurement of ...

Voice over BTLE?

I have a project that requires full-duplex voice comms (doesn't need to be high-quality). I'm evaluating the suitability of BTLE for the task. The new nRF52 has a PDM module for a MEMS microphone, which is a great start http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52.v1.0.0%2Fnrf52_series.html&cp=1but I wonder if Nordic will 'officially' provide voice comms as part of their software modules; that is, a custom protocol will not be needed to be written. I've seen similar ...

Hi All,I'm using ble_app_uart Application to send some notifications from Peripheral to central device. I'm using API ble_send_string() to send notifications to other Mobile APP. When i test this setup on nRF UART App, it works fine, nRF App shows single data transfer for single button press on ble device. But on our custom App, we get sometimes single data and sometimes multiple character data change notifications for single button press (ble_send_string() API called only once). Although i am sure i'm no...
