    is it possible to ZIP a file using STM32F4 ? Any library available?

    HI,I tried this but its not working.Even its not a creating a file with .zip file extension - - - Updated - - - I could find a webpage and in that someone said he generated ZIP file using miniz library in PIC32 https://demin.ws/blog/english/2012/09/18/miniz-minilzo/

    is it possible to ZIP a file using STM32F4 ? Any library available?

    gzip wont work for me.I need to get it as .zip format .Because I am sending this to another server,the server can handle the file with .zip extension.I don't have any access to the server as this one is managed by some other people

    What is inside a car shock/impact sensor?

    You are correct..Thank you - - - Updated - - - May be that will work if I try to do that.But in end product I need to cover 1m with one sensor

    What is inside a car shock/impact sensor?

    Okay.Thank you very much for your comments But I am still curious about how they are achieving this by just connecting a small box under the dash board.I couldn't find any sensing element and all they are connecting a box only.If if detect the vibration ,the received vibration level will be...

    What is inside a car shock/impact sensor?

    Hi , I was trying to make a shock sensor.My idea was use a small condenser mic and detect the vibrations,and of course it works.But when I need to cover a large area for example 1mx1m area its difficult .Then I searched for the shock/impact sensors that used in old cars(I am not sure this is...

    How robotic camera like SoloShot work?What technology they use?

    Thank you very much,If they say there need an additional device for indoor operation then that means they are using a default system that can work in outdoor only,right? :) So most probably its GPS.:) Also do you think and RF beacon method can work perfectly in a system like this? - - -...

    How robotic camera like SoloShot work?What technology they use?

    Hi All, I happened to read about 'personal robot cameraman' devices.There are a number of devices available in the market SoloShot,Pixio etc You can watch a YouTube video https://www.youtube.com/watch?v=tc7AZWaHm4o .Basically its a robotic camera that can follow you and you have to wear a...

    Communication between Arduino through Xbee not working.

    Okay,Thank you very much.As I already bought NANO compatible IO boards now I have to use the nano itself.

    Communication between Arduino through Xbee not working.

    Okay,Thank you very much.BTW all of the nanos are 5V or is there any 3.3V versions?.The IO shied is compatible with 5V version ..right?

    Communication between Arduino through Xbee not working.

    Okay,I have searched a lot but I couldn't find out any,In any time if get that webpage kindly let me know Thank you - - - Updated - - - Let me ask you one more think I am planning to buy these arduino nano **broken link removed** And this NRF board **broken link removed** Do you think both...

    Communication between Arduino through Xbee not working.

    Okay,Thank you very much.I directly connected 5V to my old NRF24L01 chips,so i think they are already damaged:).Anyway my IO shield will reach here in 2 or 3 days(the same one that you shared the link) and once I get it I can test the code in real hardware. BTW if you don't mind,is there any...
