 Hi everybody, my name is Mauro Scanduzzo, I'm a Field Application Engineer for ST Microelectronics. I'm working specifically to the MEMS sensor and what I'm going to present to you is the way to update the firmware of our Profi MEM2 that is the MKI-109-V3. We're going to do step by step through our website which tool we need to install and how to update the firmware. So the first thing to do is go to our website, so it's www.st.com. When you reach the main part, just on the search area, please look for this particular hardware that is called 109-V3, this particular STIVAL MKI-109-V3 that is the motherboard. On the section tool and software you have the graphical user interface called Unico. You download this package, scroll down the page and just press get software. Accept the condition you need to have a login and password on st.com. If you don't have, please register yourself when you are in. As a user, in this case appear my name, scroll down again and you download. Perfect! When you are finished to download you can open the folder. It's going to be a zip file, you extract it and inside you have this folder with documentation, driver, in case then you need a driver. At this point then install the driver, so what do you have? You have an executable here, you run the executable to install in your PC the Unico GUI software. Next, you accept the agreement. If you want you create a shortcut in your desktop, otherwise not and you install the software. At this point Unico is here, is available. What you need to do is now update the firmware on the board. So the first thing to do is close it, go to the website again, the software tool to update the firmware, then it's called stn32cubeprogrammer. It's the first one, you click this, you scroll down and you want to get the software, so you download also this. You accept it, if you want to save, you save in the same folder that we used before. Perfect! When you finish the download you open the folder, this is the zip file, you extract it and you run the executable. Press next, next you accept the license agreement, next you install as a default in this path then is the microelectronic stn32cubeprogrammer. Yes the target will be created, you press next and now it's just starting the process to install the software in your pc. Press next, you install again the driver then you already installed before, you finish the process, press next, next and done. At this point you have the two tools. One is Unico to manage the communication with the profimam board and one is the stn32cubeprogrammer and is the tool that you're going to use to update the firmware on the board. So the first things to do is when you have your profimams you connect through USB to the cable and you press this button here on the corner on the left upper corner and you connect the cable. At this point if you go to your computer manager you're going to see in device manager then the device is connected as stn32 bootloader. At this point you can launch the stm32cubeprogrammer, you need to connect these through USB you press connect. At this point the tool is going to read the contents of the flash inside the stm32 embedded on the profimam board. At this point you need to open a file to update the firmware. So if you go in the installation part of Unico, installation part of Unico will be your C code, your C driver, stmprogram files, you are looking for stm stmicroelectronics folder. Instead of stmicroelectronics folder there is another folder and it's called Unico. You go inside there is another folder and it's called bin, dfau and inside this you find the binary. You open this is the specific binary for a profimam tool so you open that and you need just to download. At this point start the process and you update the firmware of your profimam tool. One is finished, find download is complete, you press ok and you need to disconnect that because now you are working in debugging mode so you disable that. If you go back to the device manager at this point if you remove the board and if you plug again the board has been recognized at this point with a common port associated and actually is the common port 3. So at this point you can really launch Unico then you already have installed. In this particular case I have an adapter of an accelerometer stand alone, in particular I have an adapter with the LIS-2DW12. If I scroll down the LIS-2DW12 is this one and the part number is MKI179V1. I select that, I leave the communication with the motherboard enabled and the automatic recognition on the common port. I press that, the graphical user interface open with the common port 3 in order to communicate with the hardware. I start the communication, I go to the second tab then is options, I press easy configuration because the default setting of the accelerometer is in power down so we don't sampling anything from the mechanical element. If I press easy configuration I have a pretty full configuration with the 2G high performance mode with an auto data rate of 100Hz. I can press the plot on the vertical bar and now I see my accelerometer. So in this case I see the gravity is on Z-axis, if I flip over the board I see the gravity go in minus 1G. If I rotate at 90° I can see then the gravity go in a different axis actually is a Y-axis. Thank you very much today for watching the video and so if you need any kind of more information please go to our website www.st.com you can find a lot of information a lot of collateral and please enjoy the experience to work with st.com.
