This concerns us all.
this new family is very interesting, but you have to discover it step by step. this is what i'm going to do with a little development card. The first notions :
lighting a led, displaying with an LCD and making a buzzer work.
then we will go further with your collaboration. This is a complement to Mark's samples.[img:34dca9a9ee]https://www.mcselec.com/userpix/115_20220127_172449_1.jpg[/img:34dca9a9ee]

I reserved some ports for I2C, SPI and serial port. The added zip file gives the schematic

Each time you use this µp with a new sensor, or a new application, you can complete this post
many thanks

:wink:

Hello _jarek_ and Mark,

I tried the DAT for the 192, works great.
Thanks for the great support

Have a nice weekend
Andreas

Haha. Much as I've enjoyed the back-and-forth of this particular tennis match, it's time to go and make and test the thing.

Besides, I'm terrified that you might find yet another flaw in the circuit :wink:

i used Jacek's version and modified it slightly.
i also added the 192c3 version.
not tested with real hardware but based on atmel inc files and other tested dat files.

You want to duck out just as we succeed over-engeneering it? ;D

Hello _jarek_
perfect, i will check the DAT file. May you have also a DAT file for the ATXmega192c3 type?

Ciao
Andreas

hello, check out this version:

The supply is half wave 24 VAC so can supply the voltage and current to lift the output even when the maximum supercap charging current of 33 mA is being drawn at power up.
I've changed a couple of values to try to improve the performance. I had to use the LM317 in the simulator as there is no 3.3 V device in the library.
The Power_on sense voltage (green trace in the graph) rises to the input high threshold (~1.75 V) 6 seconds after power on. Vbat reaches the 1.8 V BOD level after 105 mS and the supercap reaches that level after 17 seconds.

I'm happy with that behaviour.
Thanks to everyone for all the suggestions and exchange of ideas.

Hello
Please help me, I want to use hardware counter for external pulses on ports d.1 and d3 (Xmega128)

od portd.1 work good, but I don't know how make it for portd.3 at the same time

[code:1:209c39e0f8]
Config Event_system = Dummy , _
Mux3 = Portd.1 , Mux2 = Portd.3

Config Event_system = Dummy , Mux0 = Portd.1
Config Pind.1 = Input
Config Xpin = Pind.1 , Invertio = Disabled , Slewrate = Disabled , Outpull = Totem , Sense = Falling

Config Tcd1 = Normal , Prescale = E3 , Capturea = Enabled , Event_source = E3 , Event_action = Capture 'stary

'interrupt every one second
Capture_e:
cnt1= Tcd1_cnt 'counter pulses portd.1
Print#1 , "p" ; cnt1
Tcd1_cnt = 0
Return

[/code:1:209c39e0f8]

Let me say: my apologies, as I did not understand your intention.
[quote:e58af96ec1]We may have been talking at cross purposes.[/quote:e58af96ec1]
Yes, sort of.
