Do you have Teensyduino installed?

Thank you for the reply @Yaakov , Yes I have installed teensyduino which installed all libraries also in hardware/avr/libraries
this code compiles smoothly on board Teensy 3.2
but due to unavailability of PDB in Teensy 4 this code is failing

I'm totally confused on how to proceed over this

 

Well, if you can't port the code then nothing except get a 3.2.

I can't vouch for any of these sellers, but here's some listings and there are many more on AliXpress. Apparently there must be some plans out there for cheating on a PS3 using one so that might be the reason for scarcity combined with a parts shortage.

I have not used the Teensy boards so all I can suggest is to put the Teensy 4 aside until more documentation is available and buy a Teensy 3,2 for this project:

Sorry, I dont want to buy teensy 3.2 due to time constraints as it says 45+ days delivery and most don't deliver to India, I just want to know how that code can be tweaked for Teensy 4

It's not a matter of tweaking, it needed to be ported because the code is hardware dependent. Perhaps you can hire someone to do it.

 

I did the search you should have been doing and found this: I believe it supports Teensy4:

He said he.is using Teensyduino already. The trouble is a hardware incompatibility between the 3 and 4. The 3 has hardware Programmable Delay Blocks and the code writes directly to registers that aren’t there on the 4.

But which version of Teensyduino is he using? Version 1.56 is supposed to support Teensy 4.

It could be a problem if he is not current but this situation is limited by the hardware incompatibility even if he’s got an outdated Teensyduino.
