ATtiny1616 ADCX WCOMP into EVSYS
Hi all, Wondering if the ADCX WCOMP when triggered generates the event on EVSYS. It doesn't mention if the event is from ADC sampled, WCOMP or both. Cheers Andrew...

AtTiny1616 - A better means to control/override TCD0 outputs
Hi all,   I have TCD0 generating a square wave outputting to three outputs   //TCD0     TCD0.CMPACLR = 0x09;        //Clear A...

Converting a float into an int with greater than 11 bit exponent?
Hi All, This has probably been asked for in some shape or form. It's not a problem I've come across as I rarely do float maths, but the PID library I'm using is doing just that....

I2C library using INT for clock-stretched write?
Hi,   Just extracting myself out of Arduino where going through the code they use I realised they're looping to write to I2C.   I need to recreate the 2004 LCD library...

Segger "cannot compile this l-value expression yet" on most peripherals
Using the latest version of Segger Embedded Studio which supports SAMD21 CMSIS out the box. I can see that samd21.h is importing samd21g18au.h which is correct.   EIC-...

SAMD21 -> External Interrupts Lock CPU
After many days a user kindly found why my external interrupts weren't firing. This is resolved, per say. I have other interrupts working fine. As soon as I press a button, which...

SAM21 -> Ext Interrupt Code Review
Hi all, Going to be a few of these type of questions I reckon as I get to grips with this CPU. Here I've wrote a handler for 6 buttons. I'm still restricted by the Arduino...

SAM21 Clock(s) Crash Course
Hi, I'm upgrading an AtMega2560 to a SAM21 board and am struggling to make sense of all the clock options. I'm hoping for a crash course! The project doesn't need any power...

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 {  ...
