AtMega2560 -> Maximum ADC Frequency
I've an Arduino almost entirely reconfigured with the software as optimised as I can get it. Interrupts do little work, set flags and work is done in the loop.   There are...

ATtiny1616 -> Comparator Latch Hack
My LUT's are all used up and I'm trying to get creative with a latch and the event system. In the diagram below the comparator is one of the three internals, so there are three...

ATtiny1616 -> Comparator Hysteresis Variance
I'm using a resistor divider, the fabulously low 0.55v reference, and "50mV" hysteresis to net a turn off and on point of the equivalent of 9.5v and 14.5v. It works very well...

ATtiny1616 -> VLM Fairly Broken?
Hi, Depending on what source is used (a few are attached), and which version, the Attiny1616 might support the following levels -   typedef enum BOD_LVL_enum {  ...

[Code Review] DIY C Buffer Filter/Analysis Function
Hi,   I've a circular buffer presently holding up to 30 reads (period of a frequency). Occasionally some noise creeps in which I need to deal with prior to calculating...

ATtiny1616 -> CCL LUT And Edge Detection Woes
This problem is killing me. I've been on it for two days now and wondering if I just have stuck with PIC16.   Inputs (all working)   AC0 -> Over Voltage AC1 ->...

ATtiny1616 -> Zerocross Detection Circuit using AC1/DAC1/FVR
Hello all,   I've a zero-cross circuit for low Hz (<200Hz) but potentially higher voltage (80v) which is working well in terms of reading a signal but less so in terms...

Attiny1616 -> TMRB Repeated event when interrupt not cleared?
Hi,   I have a conundrum to verify. I've three comparator signals; one is for reset, one for over-voltage and one for under-voltage.   If over-...

ATtiny1616 -> ADC or CMP for shunt current measurement
Hopefully my final ATtiny1616 question. I've a circuit where there's no space for an op-amp and a requirement to do a very rough current usage approximation. As there's no space...

ATtiny1616 -> ADC0 Window Comparator Int won't fire
Been on this one two hours now and still a no-go. ADC is using 0.55v ref, channel is correct, global ints enabled. I've give it a very low WINHT value just to be sure it'll be...

ATtiny1616 -> Frequency Measurement (TMRB) Diagnosis
I've a 20Hz signal coming in to AC1, which interrupts correctly. I feed the output via EVTSYS into TMRB0 which has been set up for frequency measurement on falling edge...

ATtiny1616 -> Releasing WOx from TMRD
Pin PC1 I have set as an output. As this is is also controlled by TCD I've ensured the FAULTCTRL register for that pin is disabled.   TCD0.FAULTCTRL = 0; PORTC.DIRSET = 1...
