Thanks, I also use a RPi3; last week, I began to make an UI, draw on canvas; now I will explore what I can do whith ThreadpoolTimer; I do'nt know how to use it; I found something with Dispatchtimer and time span (run in local but yet tested on RPi): declare: Dim tsr As New TimeSpan (10000000)' 1=100 ns Dim tmr As New DispatcherTimer Dim i As Int32 beginning: Private Sub Btn1_Click() tmr. Wow Hits 2014 Download Rar here. Copy Crack Into Install Directory. Interval = tsr AddHandler (tmr.Tick), AddressOf tmr_Tick tmr.Start(). Action: Private Sub tmr_Tick() i = i + 1 Btn1.Content = i End Sub. Hi IotGirl, For windows universal (in Visual studio) I find 14.0.25527.01; up to now, I have only send to Rpi simple programs with Buttons and canvas to see if I can install Something; I try to make running first the main in Visual Studio ( universal). Back to ThreadPoolTimer; in the xaml.vb page, I can't create one ThreadPoolTimer; if I create a class ThreadPoolTimer, I can create Something (dim Tpt as new ThreadPoolTimer); after Tpt is known but I can't add no property TreadPoolTimer has good methods and I ask myself how Erik has use ThreadPoolTimer to make timer. So I use old App and fill it with new code; and for Dispatcher Timer, it works in Debug mode and release on the Rpi,but very bad; steps are lost and maxi speed of this kind of timer is around 20 steps/sec (50 ms, even jf TimeSpan.frommillisec is 5); to drive the motor, I use small interface board (kind TB6600),with use of 3 pins:step, sens,enable; run very well Under python Linux, I must see with oscilloscope what is on Gpio pin with IoT; but the way was right, because I could update (if wanted) the canvas and textblock.
