Incorporating TJ's new BLE code with AD5933 #14

Closed itkwon closed 9 years ago

itkwon commented 10 years ago

I just saw his code with using MSTimer library to coordinate the sampling frequency.
I think the incorporation should be done later after his code is completed. I can work on manipulating measurement cycles to modify the sampling time, but it is not sufficient.
After looking after his code, there is a some routine with if statement, if the writer is true. I saw that it is true when the timer is activated. I think the code for measuring impedance should be inserted in there.
Also, I need to work on to find a right cycles to measure the signal, and find a way to incorporate by modifying the library.

TODO
1. Modify the library not to wait during the acquisition. 2. Add function to check whether the value is ready. 3. Do some experiment to calibrate the cycles to measure.

After the Android can input frequency sweep.

  1. Program the Arduino to change the Freq 1k-100k (Current: 50k)

Plan to incorporate AD5933 into BLE

  1. Changing Measurement Rate in Non-Sweep Mode
    1. Set REPEAT_FREQ after send a data.
    2. Get a data
  2. Sweep Mode
    1. Probably receive the result in array.. How to transmit?

Pre-programmed to incorporate BLE and AD5933 for non-sweep mode.

BLE_Debug_Timer is complete on my side. Il Taek, you should be able to view it and update your library accordingly.

tunjid commented 10 years ago

Note: from the app, the user can write in 2 ways:

  1. The user enables frequency sweeps and writes 3 values: the upper frequency, step size and lower frequency.
  2. The user disables frequency sweeps and writes a single value, the single frequency to the upper frequency. The remaining 2 vales will be written as 0.

You should probably use this as a check for your library whether to trigger frequency sweeps or not.

Thank you for letting me know. I think the notification mail went to spam folder. I read your comments, and thank you, but I cannot work right now. I will work on from Thursday. Hopefully, I can work on if my tasks are completed early.

No problem, take care of school business. Chat with you on Thursday. On Oct 6, 2014 12:28 PM, "Il-Taek Kwon" notifications@github.com wrote:

Saw that TJ updated new incorporated form. I will work on it.

I think TJ(@tunjid) already have done this.
