ATtiny implementation stops working after some time #2

Open simonsunnyboy opened 3 years ago

simonsunnyboy commented 3 years ago

After a certain usage time depending on the system to which the prototype is connected, it stops working and button presses on the SNES pad are not registered anymore.

Plugging out, waiting some time and plugging in makes it work again.

Observed on Atari STE: approx 1,5h until device becomes erratic Observed on PC with DB9 to USB HID joystick interface: approx 10min until device becomes erratic

Assumption: RC oscillator of ATtiny becomes irregular on heating up.

Stability to be tested with a proper oscillator added to the design. Verification first with more stable Arduino implementation.

The Arduino Nano/Mini Pro version suffers from the same problem. There the erratic and stop behaviour starts after about 10-15mins being connected with my USB converter.

I presume this is still an issue?

I was hoping to use your ATTiny adapter to connect a SNES controller to an Amiga 600 but it looks like you haven't uploaded a schematic yet?

Thanks
