I should do a production run of my analog-toolkit, my small STM32G431 dev-board. It comes in handy again and again, I have broken out most useful peripherals, USB, PD, UART, I2C, HRTIM, TIMs, Op-Amps, Comperators, the DAC and of course a bunch of ADCs (with on board capacitor, pull-up, pull-down and biasing options).

I just recently used its ADC and comperator in parallel to measure the time between two tigger events. The ADC was reading the averaged analog rail on which the trigger event occurred, setting an internal DAC to the negative comperator pin, with the the analog rail going to the positive comperator pin. The comperator was then set to start and stop a timer. Basically an automatic trigger voltage was measured and set via the adc, while high speed trigger events triggered the comperator, handy!

Assembling a few this evening by hand, a friend asked me for one. I should really have a few assembled, giving them out to friends, like with the OtterPills!
