Would it be possible to accept data from two seperate serial ports and plot the received data on one chart?
Also could we have a feature to add a scale(s) for X & Y axis?

Thanks

I am trying to measure roll and pitch degree of moving object (sort of a cylinder).
I am bit of confuse, is that your algorithm can measure roll pitch degree of moving object?

Thank You

Instead i used this code, but on the serial Chart i receive random symbols.

hdlc_send_float(Interval_msec);
uart_send_char(“,”); //
hdlc_send_float(Xaxis);
uart_send_char(“,”);
hdlc_send_float(Yaxis);
uart_send_char(“,”);

This post just to submit an issue about SerialChart. Having multiple USB/serial transceiver (i.e. FTDI chip) connecting different development boards, the virtual COM number assignement may grow quickly. In my case using COM5 I can connect the serial port but usign COM19 I can’t: SerialChart returns a message box error “Could not open port COM19″.

Could be a bug in the COM port configuration parser that only forsee COM port names ranging from COM1 to COM9? I get the same messages with all COM port with two digits number.

What is the purpose of tmpf *= interval / 1000.0f?

I get what it does (multiply tmpf by time stamp difference once divided by 1000 for unit conversion?), but how does that actually calculate the angle change in degrees?

Thank you,
Keehun

I’m a novice programmer, and just getting the data is hard. If you don’t do it, or don’t have the time, do you know anyone knowledgeable on the iPhone4 who might help me?

Thanks,

I am building my final project that using accelerometer, i am using your Serial Chart but i have some problems with it,

first, why it response (due to the changing of accelerometer value) become so slow.. my input for serial are :
320,333,367
320,333,367
319,333,367
319,333,366
320,333,367
320,333,366
319,332,366
320,333,367
319,333,366
320,332,366
(represented my analog read of accelerometer using arduino..)

Second, i want to make my chart to be more ‘zooming’so it will make the detail of the chart bigger,

could you help me how to do/fix those things?

I am building a balancing robot (prototype for a Segway really) and using the IMU & Starlino code, however, I have a few queries:-

Using RwEstX I amd finding there’s too much lag and as a result my motors don’t respond quick enough. So, I have been trying RwAccX which is a good bit faster, but lose the benefits of Est.

On my Arduino (328 powered) I have measure my main loop scan time at over 5mS, which I believe doesn’t help much.

Finally, the output range of RwAccX/RwEstX is -1.00 to +1.00, and so by the time I multiply that up to suit my PWM output values required then I’m losing a good bit of resolution, especially around zero where the deadband created by such means my motors don’t react.

Any hints/tips?

Ian.
