Teensy 3.2 + USB Host Shield #700

Open escape-lib opened 2 years ago

escape-lib commented 2 years ago

Hi all,

I'm really at a loss here. I purchased the full sized USB shield (as I couldn't get the mini in Australia) to use with my Teensy 3.2. On my Arduino UNO it functions perfectly fine, however with my Teensy, it fails the board_qc sketch.

`Circuits At Home 2011

USB Host Shield Quality Control Routine

Reading REVISION register... Die revision invalid. Value returned: 09

Unrecoverable error - test halted!!

0x55 pattern is transmitted via SPI

Press RESET to restart test`

My pin connections are as follows (following this SPI hookup guide: https://www.pjrc.com/teensy/td_libs_SPI.html):

INT -> D9 SS -> D10 MOSI -> D11 MISO -> D12 SCK -> D13 3.3V -> 3.3V + RESET GND -> GND VIN -> VIN

VBUS is jumped to 5V & my VIN coming from the Teensy is 5V.

Thanks.

Not sure if it's relevant, but the Value returned: 09 only returns 09 when there's no USB device plugged into the shield. Once a USB device is plugged in it returns 00.

it isn't. See the state machine return values.

it isn't. I don't see why you would want to use this library on a teensy 4.1, especially since it already provides EHCI USB, which is high-speed USB.

I’m using a Teensy 3.2 (as said in the title and the post) not a 4.1 - the 3.2 does not provide native USB host capabilities.

it isn't. See the state machine return values.

I'm unsure of what you mean by the state machine return values - I couldn't find reference to that in the documentation.

Unfortunately, UHS2 scatters the codes. https://github.com/felis/USB_Host_Shield_2.0/blob/a321ad36ab4dd9ea000ffa809532a937ffca06d0/UsbCore.h#L90 and... https://github.com/felis/USB_Host_Shield_2.0/blob/master/max3421e.h#L214

PIDERR is 0x09
