LOL… :sunglasses:

every year a supprise how they will taste… this year I’m not really excited :wink:

btw you’ve seen this ?

conclusion : use a better TXCO

I like them!

in general… or this year ?
last year’s Herring was a bit fatter / smoother but ok… I’ll go to the shopping center later today and have a few more… just to be sure :wink:

Honestly: the few times I had occasion to eat fresh herrings in Netherlands I always liked them and I would not be able to tell the difference. :yum:

any news on the supercap front… NO not really :sunglasses:

mayby this… what about 4x paralell ?

but ended up buying a few of these :sunglasses: for solar experiments/nodes
I think a little solar panel + reverse protection diode will do the trick for a small LP node

Is there any recommended 'tool out there , that can recognize what bootloader is currently on the target 328p 'system ?

I only found this article from Nick Gammon
http://www.gammon.com.au/forum/?id=11633

@BoRRoZ, the bootloaders I’ve put there https://github.com/hallard/Pro-Mini-ICSP-FTDI are just (as mini core) from official optiboot https://github.com/Optiboot/optiboot

I just compiled them and placed them to avoid you nasty compilation stuff and because 2 years ago, I opened an issue to Minicore to ask to put the compiled version with serial of 250K to minicore for 8MHz and It was rejected.

I’m glad now minicore have these compiled version and even with 1M speed, so you can use them with no problem, they should be the same.

Take care of your crystal, if you are using 8Mhz you will have issue with speed 115200, see my old article here
I strongly suggest using 250K version, will works every time at 4, 8 or 16MHz

Bonjour @Charles ! :sunglasses:

tnx for the info.

I want to burn it on the mentioned module which has an 8 mhz x tal… don’t know anything about the qualtity so I follow your advise.

Which programmer do you have ?

I was thinking using a 3v3 arduino mini pro

:sweat_smile:

Yes it’s do able of course, but programming fuse and other always a headache like that because all are in config boards files and you don’t really see if all went fine.

My 2 cents, and what I’ve done, buy a real AVRISP MKII (no more manufactured) programmer and flash with Atmel Studio as described here https://github.com/hallard/Pro-Mini-ICSP-FTDI
Note to low down 5V output to 3.3V to avoid burning RFM95 during flash process :wink:

I was able with low cost chineese programmer after again headache burning another firmware to get them working with arduino IDE flash.

This one should works

thank you Charles… I will first study all this before burning anything :roll_eyes:
