@MarkT and @Pio - Thanks so much for you help with all this. Pio - your reference to that TI document was a lifesaver. I really like the circuit you've laid out and would go ahead and construct it if it werent for the fact that Im already way...

@Pio - Thanks for the attention to this. Do you have any suggestions as to how to do that? Read that TI note and very useful. So - and correct me if I’m wrong - I should put a capacitor across the second stage feedback resistor of value...

Mark - Thank you. In this application the teensy pin is set to output as I am using the teensy to modulate a -10/+10vdc signal. Wouldn’t setting it to input_disable obviate that? Also, there are 1uF capacitors at both power supplies into the...

All- I am using Teensy 4.1's for my static Boeing 727 simulator which uses OEM parts and have run into an issue using opamps with the Teensy. I have designed a circuit to use the 3.3 PWM output of a Teensy 4.1 channel to modulate a -10 to +10vdc...

All - Thank you for the help. After reinstalling everything, I noticed a small but ultimately significant error in my code which I think led to the problem. I had introduced a ‘float’ variable when I should have introduced a ‘FlightSimFloat’...

@MarkT - I thought that using that command wasn't necessary with the Flight Sim Controls line checked in the Tools/USB tab (none of my other sketches use it and they work fine). As I said, it compiles and will load on a 4.1 but not on the 3.5...

Mark - You are correct but that occurred when I copied it into the post. I made sure it’s not there and it’s still throwing that error. Thank you & 73’s! Jon KA3BPR

Hi all - I am new to this forum and very new to the the Teensy. I appreciate any advice anyone might have as to how to solve this problem and thank you for your patience. I am building a static Boeing 727 simulator using all OEM parts. One...
