Hello,
I am using a Teensy 3.2 as 16 bitd digitizer into a Pulsar receiver for my radioastronomy hobby http://f1ehn.pagesperso-orange.fr/pages_radioastro/Images_Docs/PSR_Mes_2016_revA2_Eng.pdf .
I need to improve the clock stability to be better than 0.5 ppm.
I plan to remove the Teensy 16 MHz crystal and enter an external clock to the EXTAL input.
I have read the Chapter 25 OScillator on the " K20 Sub-Family Reference Manual".
Hardware seems clear for me but I am not clear with the Software update.
My SW is based on the OScilloscope application http://people.cas.sc.edu/rorden/SW/oscilloscope/oscilloscope.zip
and the stinsyncArd.ino firmware.
Sorry, I am an RF man and not a programmer ;-)
Anybody could help me on the SW modification (If needed) to put the Teensy 3.2 with an external 16 MHZ clock ?
Thank you and best regards.
