Can’t control the aux, all just being static.
Trying to reset doesn’t seems to do anything.
Measuring pin 7 I measure 60mV from it, oddly when probing this pin with my mutimeter the output actually spit something out.
I then connect the driver to battery and hook up an LED to the output to see if it actually a meaningful current, and it is. Proding pin 7 light up the led just fine
Stupid question: is the switch working? Should be PC3 / pin 18, and I’d expect it to be high when not pressed, and low when pressed.
Probing in voltage mode or contuinity/diode? Do you have the EN pin wired high?
yeah, the e-switch is fine. Its high when left floating.
Voltage mode, didn’t do anything to EN pin. Need to find my second multimeter to see if that pin actually goes high when I measure pin 7
Just remeasured it, there is actually 2.9V from pin 7, it follow the supply voltage minus ~.4V when I change it.
I don’t think it suppose to do that judging from the code?
We’re talking about pin 7 on the at1616, right? If so, that’s very odd as it should be the DAC output, which should be no higher than 2.5V. Seems like the controller isn’t working at all.
yeah, pin 7 on the mcu. Can’t really tell if the ATtiny1616 is broken or fw is hecked in it, we’ll see in couple of days when I can reflash it
Is it have DAC?
The ATtiny1616?, yeah.
PA6 or pin 7 in 20-Pin VQFN version, supposed to be the DAC0 output
this is definitely wrong, either with the FW or the mcu itself. Nothing else I can do for now without reflashing it.
the code call for 2.5V for the DAC0, unlike what its doing on my driver
Yes MCU do have but is it used ?
Not on mine, but it supposed to.
The code set the DAC0 for pin 7 to be 2.5V, but instead the output is following the driver supply voltage -.4V like I mentioned earlier
So either the mcu is broken or the code inside it, since this also happen with pin 11 to enable the buck and op-amp, nothing else to do currently aside waiting for my flashing kit.
I could be wrong on these as its not my expertise, but its almost definite that the issue with my driver is from the mcu itself, with it not outputting proper signal and it not responding to the e-switch presses
