So its now 100% working! It turns out I wired DAC0 to the wrong pin on the shield . Had fixed the software side long ago and just didnt know.
Thanks for the help, its a nice bit of software the serial commands you’ve made are really handy! For anyone else who has issues and googles their way around hopefully this thread can serve as an answer to save you the time…
GUIDE to using Teensy 3.5 and prop shield with Proffie OS 5.9
If it dosent work after doing these things you probably have made a wiring error or your SD card is too slow or loaded with the wrong files.
The pjrc prop shield fits on the teensy 3.5 fine. Line up the GND in the top corner of the shield with the GND on the teensy I reccomend you only use pins where they are needed to save on soldering and if you make a mistake. I used male and female headers.
The teensy 3.5 has a slightly different pin layout so you need a jumper wire from pin 22 to DAC on the prop shield. Note the writing is at an angle so its easy to solder to the wrong pin… this wont do any harm but it wont work. (See purple wire in the photo)
I’ve attached the config files I used feel free to just use those. To do it manually there are very few changes you need to make.
The internal SD card is enabled with this line
sdCardSelectPin = BUILTIN_SDCARD
you will also need to make sure that the include for SD.h
#include <SD.h> has been called before this line. I just put it in at the top of the config file.
