Migrate projet teensy 3.5 to teensy 4.0

pedroborges · Apr 18, 2025

good, i was using teensy 3.5 with the code controlling a led panel and it works well.

i bought a teensy 4.0 to try it out.

I changed the arduino program to teensy 4.0 and uploading a lot of errors.

with teensy 3.5 the code works fine, but with teensy 4.0 no longer.

I am attaching the library files configuration that I use in Teensy 3.5

link libraries teensy 3.5 - https://we.tl/t-ciXNfrXTq1

would appreciate help

It would be more useful to post the code you tried to use on the T4.
Have you read the file MIGRATION.md in the SmartMatrix-master directory? It describes some changes that are required to get that library working on a T4.

It would also help if you posted some, or all, of the error messages.

thanks , I didn't read the migration file; I removed the library I was using for Teensy 3.5, and installed the new library to use on Teensy 4.0

el_supremo · Apr 19, 2025

You may be using the correct SmartMatrix library for a T4, but your own code is still expecting a T3.
For example in Boardinfo.ino you have:

Code:

/*
 Read the MAC address
 http://forum.pjrc.com/threads/91-teensy-3-MAC-address
 To understand what's going on here, see
 "Kinetis Peripheral Module Quick Reference" page 85 and
 "K20 Sub-Family Reference Manual" page 548.
*/
void readMAC(uint8_t word, uint8_t *mac, uint8_t offset) {
  noInterrupts();         // Disable interrupts
  FTFL_FCCOB0 = 0x41;     // Selects the READONCE command
  FTFL_FCCOB1 = word;     // Read the given word of read once area

The comment indicates that the code is written for Teensy 3. You will have to find the equivalent function for a Teensy 4.

Similarly, the errors caused by this statement in the configureInputDMD function in InputDMD.ino:

Code:

  CORE_PIN10_CONFIG = PORT_PCR_MUX(2) | PORT_PCR_PE | PORT_PCR_PS;

are because it is specific to the Teensy 3 architecture.

You'll have to figure out how to replace these, and the other errors in Watchdog.ino, with code that works on the Teensy 4.

Pete

pedroborges · Apr 19, 2025

Thank you, because I am already using the SmartMatrix 4 library.

The question is what kind of changes I will have to make to the code

pedroborges · Apr 19, 2025

The old library was smartmatrix 3, I removed the smartmatrix 3 library and put the smartmatrix 4 library

el_supremo · Apr 19, 2025

Yes, the problem isn't with the Smartmatrix library.
The problem is that the original code written by Eli Curtz (i.e. all the code in your RGB_DMD_Branco directory) is written specifically for the Teensy 3.2 and uses code which directly accesses the hardware registers of the T3.2.
It will not be an easy task to convert this code to work with the Teensy 4.0 or 4.1.
