Hello, from what I understand the CW-Lite does not allow triggering/glitching off a GPIO line 1 time at a specified time after AND then a second time at a specified duration (only 1 gpio trigger event). The second time glitch is allowed only on the Husky?
I currently have 1 glitch upon resetting the processor working, but it seems I need a second glitch to get past the second stage protection.
Note: This is executing in boot ROM so I can’t add GPIO flips in the code itself.
Right now i’m triggering off a reset line of an STM32 processor. I’d prefer to have 2 glitches based off the reset line. If that isn’t possible, trying to figure out different ways to achieve the same results.
So, I’m looking at options:
- Set up a second microcontroller to do the glitch via a fet
- Set up a second microcontroller to sample the reset line and set a gpio out, then flip a gpio a period of time after that. And I could set continuous glitching so it just triggers off both gpio flips
- Figure out how to implement what this person did. I’m thinking this will be too painful.

erm it seems what i really want is num_glitches but it is husky only.
