Hi,
I started to use attiny85. bootloader uploaded using arduino isr and blink sketch uploaded using digispark clone using this tutorial.
I had much success. led is blinking on programmer (pin1). I see which (physical) pin is making the blink using my multimeter. I made sure to get the GND and 5V pin right.
HOWEVER - when I take the attiny out of the programmer and onto a breadboard (just gnd + 5v connected) - same pin does not "blink" (tested same pin with same multimeter...)
it seems to be something the digispark clone programmer is doing which I am not replicating on the breadboard. I have tried to pull up the (already pulled up) reset pin usink a 10K ressistor - no change there...
anyone had this issue before? could not find this in this forum...
i am a experienced arduino and esp boards programmer.
I'll appreciate any help.
edit - just to note - isp programming via arduino works just fine. I suspect fuses setup to match some protocol on the programmer...
