Hi guys, I am a software engineer and I am working on a new wearable prototype (wristband kind).
At the moment I used an Arduino Uno starting kit to start to configure my Android and iOS SDK just to make some proof of concepts.
Right now I am in the phase of choosing the first development board for my physical prototype. The idea is to work on ARM Cortex A for low energy comsumption but also ARM Cortex M is interesting even if I believe that its power will blow away the battery in few days.
Before desigining any custom PCB I want to test out an ARM Cortex, plug my sensors, write the internal OS of the wearable and more forward from there.
What development kit do you suggest me to start with the evaluation of the ARM Cortex MicroCrontroller and mbed OS system?I have few requirements to start with:
About the sensors I don't really need a development board with already a gyro or other sensors in it. But I want the possibility of tests my own sensors with mbed OS.
It would be nice if you can point me to some development board kits like the Arduino Uno. Then from there my plan is to slowly design various versions of my custom PCB as soon as I have a stable prototype done with the development board.
So after some researches I came up with a first development kit board. You guys have also to consider that now I am based in Turkey and only some distributors can reach me here without the burdain of paying tons of import taxes.
Below is my BOM and the motivation
Development board (one of them)
For sure the Sensors and the Bluetooth will require custom firmware for mbed OS but at the end I will have a custom solution.
That's my resource update so far
So, as a final choice I will start with the following components:
I will start by writing the SDK for Android and iOS and the PCB menu class. Will post some updates as soon as the hardware is delivered and I have a working sample.Note: On Nordic web site they suggest to start with the nRF51-DK because the other boards will be discontinued soon so this is why I didn't choose the famous LPC1768
Please can anyone help me,,I have a testbed for mbed board and lpc1768 MCu.
I want to connect it to bluetooth and use piezo speaker?
