 So we're here at the ST booth and who are you? I'm Davide Geerti from Stimacoleutronics and here we are presenting our ecosystem for microcontrollers for developing our products. What's the BlueCoin Plus? The BlueCoin Plus is one of our devices that we are planning to release so it's not yet available It is an example of integration of different components on one PC So what's in here? In here there is Cortex M4, there is the Blue energy, we are in tranquility and so Bluetooth 2 energy and the different sensors such as 4 microphones I prefer to do it this way. And then we have a pressure sensor, accelerometer, virus corp When you go in low power you can go For example, other kind of board that can be integrated into the system These are the only one microphone and all the sensors that we've seen before and the SPM-2L4 that is optimized for low power So low power Cortex M4? M4 What is this? This is our standard development system So there is the microcontroller on the white board at the bottom and then you can add functionalities by adding different expressions In this case we mounted the Bluetooth low energy chip and the sensor board I don't know, you mentioned the board We provide also the software that you can download directly on this board and then connect this microcontroller to an app on your phone that also we provide also This is just a different configuration Yes, this is a different configuration This is a plug-in microphone system This was an early prototype This one is the new one that are already two microphone mounted on the PCB and you can add more to this microphone Do you have millions of developers working on this or is it very popular? Yes, the SPM-2L2 is quite popular now and we are trying to expand our configuration by adding new expansion below What is that? What's under here? This one is the blue coin, the same board that we've seen before but it's put inside a nice case for the demo and together with the bottom This is another case for this other board This is really our first prototype which was already printed last week and we received this prototype four weeks ago What do you do? I develop this application I try the firmware for the people to download it and try all the different functionalities In particular, I work on audio processing so we develop algorithms in order to do all sorts of stuff So on Cortex-M you do audio processing? Yes, almost all the processing is always done on Cortex-M When we need a lot of processing power, of course we use DM4 or DM7 That's developing And how much is cast for this one? This one is around $10 $10 for this? How much is that? This one is not available yet We have another one, for example, in Barcelona This one is one of the kits that we are releasing next week So it contains a thought for wearable devices And it contains a little bit of battery There is also a wristband so that you can start working to build your application for wearable devices Nice So right here you have a smartwatch case Yes, exactly And you put the PCB in there Yes, you can download the software and just try as it is and start your trials, for example, for your application And what can people do? For example? I can show you one of the demo using the blue coin board I can just turn it on and then I can connect it with my phone Now I can look for devices Let me try it This is the demo, it's normal And then, because there's a lot of interference here but then you would find it Okay, now you find it Now, it automatically discovers which sensors are available on this particular hardware In this case, there is only the precious sensor on the first page Then I can change the demo This one is a sensor fusion demo So you can see that the cube here follows the movement This is done using accelerometer, gyroscope and the magnetometer And all the processing is done by the processor It's something with the cube Cool So that's a tool You can, for example, just stream the data coming from one sensor This is the accelerometer Then I get You also can try to calculate the level of noise using the microphones You can see if I can speak really close to the board then the volume goes up instead it's quiet It goes down So you can do a lot of different things So in these two cases you have a battery Yes, you have a battery Can I get a small battery in there? Like three years? No, three years maybe not But this is really a target for low power So it's a little application dependent because if you use the low power feature it will last for days even months And you can easily recharge it Yes, we have this other board Anyway, this is just a problem It's not the final form factor Nice, so based on this there will be all kinds of new IOT and wearables People are going to start from this People develop on this platform So we hope that they will develop nice things with that
