T++ 2.0 on Arduino IDE 1.8.2 'class USB' has no member named 'Init'

davedarko · Mar 26, 2018

Hey there,

I've run into a little problem, I can't compile code that has worked before and still compiles on a customers Mac. I'm running Arduino 1.8.2 on my mac, to work with a Teensy++ 2.0 that is connected to a MAX3421E and needs the USB host shield to work. It seems to have no idea what the pins 'Pb0' to 'Pb3' are, too.

If anyone has any ideas, please tell, I'm not sure what went wrong here.

Code:

  2016-10-08 UPDATES
  2018-02-02 starting on the EEPROM stuff again
  
  EEEPROM thoughts 
  - 100.000 write cycles
  - maybe external eeprom better suited (More than 1 Million Erase/Write Cycles)
  - 1k EEPROM ATMEGA32U4 (leonardo)
  - 4k EEPROM AT90USB1286 (teensie 2++)
  - max 408 customers / rides per day
  - with 10 reads of 16bytes

  https://github.com/felis/USB_Host_Shield_2.0/issues/286
  - had to remove RFID stuff for now, due to conflicting SPI stuff

Maybe you've selected a different (not Teensy++ 2.0) board in Tools > Boards?

davedarko · Mar 26, 2018

Right, should have written that I've tried changing the board from teensy++ 2.0 to another chip/board and back again, but it didn't help.

PaulStoffregen · Mar 26, 2018

Please try again and if it still doesn't work, copy and paste the errors you get.

Your first message has this:

Code:

Warning: Board tiny:avr:nyan doesn't define a 'build.board' preference. Auto-set to: AVR_NYAN

"Board tiny:avr:nyan" definitely means something other than Teensy is selected in Tools > Boards.

PaulStoffregen · Mar 26, 2018

Also, please use Arduino > About to check which version of Arduino & Teensyduino you are using.

davedarko · Mar 26, 2018

this is something I get with every board I select, even with compiling for the ESP8266 boards... not saying that it's not weird, but it didn't seem important so far.

davedarko · Mar 26, 2018

Arduino 1.8.2
Teensyduino 1.41

PaulStoffregen · Mar 26, 2018

Well, I tried just now on Arduino 1.8.5 with Teensyduino 1.42-beta3 (the latest). I installed the libraries from these two locations (you didn't give specific versions or info where to get the copies you are using).

https://github.com/felis/USB_Host_Shield_2.0

https://github.com/jcw/ethercard

When I click Verify, it doesn't compile, but I get very different errors.

Code:

A quick search turns up this conversation on Arduino's forum about that error:

https://forum.arduino.cc/index.php?topic=377409.0

PaulStoffregen · Mar 26, 2018

Ok, I did a little digging... it seems the problem is pretty simple. Newer versions of USB Host Shield 2.0 have renamed "HID_PROTOCOL_KEYBOARD" to "USB_HID_PROTOCOL_KEYBOARD".

To make your program compile with the latest version of Arduino, Teensyduino, USB Host Shield 2.0 and EtherCard, all you need to do is add "USB_" to that name on line 109 of your program. Easy, right?

Your program also uses USB Keyboard, so Keyboard needs to be selected in Tools > USB Type. Otherwise you'll get: 'Keyboard' was not declared in this scope

Here's a complete copy of your program, with that 1 line edited for compatibility with the newer USB Host Shield 2.0 library.

  - maybe external eeprom better suited (More than 1 Million Erase/Write Cycles)
  - 1k EEPROM ATMEGA32U4 (leonardo)

  - max 408 customers / rides per day
  - with 10 reads of 16bytes

I'm sorry about the missing information and thank you very much for trying this. The truth is, I just copied it a long time ago and never thought about versions and can't find what version I used. I had hopes that the "USB init" would be indicating something more obvious.

I should refresh before posting - Paul, thank you very much!

T++ 2.0 on Arduino IDE 1.8.2 'class USB' has no member named 'Init'
