Got my trinket today. Was planning to do the internal mod.
Have been having a bit of a mare with the trinket though. I haven't had any luck with even getting it to be detected by my PC to allow me to programme it, or any other computer which I have access to for that matter.
When the trinket is plugged it, I get the green power light, and nothing else. The RGB LED doesn't blink. Doesn't get recognized as a connected device in Windows. Nothing. I am at the point now where I reckon the board is knackered and I should get a replacement, but was hoping somebody with more experience with this can point me in the right direction for a bit of troubleshooting. I am aware that the trinket has an issue with USB 3.0 ports, so have tried laptops with US 2.0, to no avail. I have tried various USB cables to try and rule that out. I have tried using Ubuntu to see if it will be detected in ubuntu. I have not even been able to get the trinket to show at all on a PC. I have ordered another USB sync cable incase this is the issue.
If somebody might have had any issues with the Trinket M0 before that might be able to offer an insight, I would appreciate it.
I've spent long enough on this tonight now, so I'm going to bed and will check back here tomorrow.
Thanks to anybody who is able to offer any advise or pointers.
If you didn't change any files - the trinket comes with some python file + a couple of others when you plug it into your pc via a usb cable. After a second or two an led starts cycling through various colours + the power led is also lit.
If you pressed the reset button twice - you see some different files.
If it doesn't show up on your computer as a drive, you should try using a different laptop. Or just supply 3.3 volts + gnd to the relevant pins as the usb port might be dodgy - if it starts cycling the led through various colours you'll know it's a laptop/usb cable or usb connector problem - otherwise maybe the bootloader hasn't been programmed or the device is defective.
