Shifter doesn't work

[Gavin-Perry]

There are lots of shifter libraries out there but I wanted something really simple (only need one bit set at a time) so I chose yours. I'm running on a RasPi Pico using IDE 2.3.2 with Earle Philhower's Board Manager The example program doesn't work. I expanded it with some Serial.print statements to find the problem. As soon as shifter.digitalwrite(bit,state) is called the program halts. I've attached the source I used. Comment out the shifter lines (//1) and it runs (doing nothing useful) with those line it halts before the first loop finishes. .ino file renamed to .txt to upload, 2 UF2 files (with and without the shifter running) in the zip file shift595digitalwrite.ino.txt shift595digitalwrite.zip

Hello

Please, can you share me the error you have (the full output of the arduino ide)

And how to configure your board in my environment to test what is happening

[Gavin-Perry]

Do you have a Pico? I gave you the source code and the compiled images that you can run. Do you get the same behavior?

Hello

No, I dont have one :c I'm trying to setup my environment as your to check why it fails (IDE, boards, etc), can you share how you setup you environment?

When I compile the library it works (for adruino UNO), may be is some invalid keyword with your board Can you also share me the link of the documentation of your board?

[Gavin-Perry]

There is no problem compiling. If you don't have a PICO to try it on you won't see the problem. Program runs until shifter.digitalWrite() is called then hangs. (I may have the capitalization wrong here, but it is correct in the program.)

Do you have any (assembler) code that is AVR or hardware specific? Removing the 2 calls to the shifter.... (//1 in the code) and the program runs fine. I tried changing pins but that isn't the problem. ShiftRegister74HC595 works fine so I can use that instead if you don't have resources to fix it. Gavin

Hello

So it compiles and generates a "binary" that you uploads to your shield and then fails, with the Serial.println you found that fails at shifter.digitalWrite() right? there is any logs of the execution?

The library depends on #include "Arduino.h" which may is not available in you microcontroller It just fills and array with the data And then writes data out Maybe shiftOut because is an arduino specific code

[Gavin-Perry]

Sorry not to get back to you. Turns out I had crossed wires to my second chip! All works fine now. Thanks!

[danny270793]

Nice to hear that, let me know any other questions do you have :)
