Considering some of the men I've worked with over the years,
it's understandable you come across as a bit gruff at times.
Puts them off balance before they can suggest you aren't
going to be part of their boys club.

Or I can just do snark and leave.?

Cuz she's peevish.? ;-)
But when it comes to RF design, tends to know more than the rest of us put together.
So we mostly put up with it.

Jerry, KE7ER

Mark,

Not at all.? ?
Its just traffic, and it was? the original complaint too much traffic
and larger stuff was harder to take...

Well, why did you reply to something long dead?? FIrst the assumption
is people use the web version and then even look at the subscription settings.
Or know they even exist, that include the wiki, photos, and files...

Oh right its groups.io, same topic needs to pop up periodically
as its been long forgotten...? ? ;)

Is it wrong to reply to older threads now?

I was looking at the group's space and attachments and saw this post about attachment size.? One option for sure is no email, but I think the OP needed to keep emails going but had a hard time dealing with large attachments.? I seached and found out that groups.io allows one to limit attachment size on emails.? I didn't know that before and thought that some others may appreciate the info.

I don't understand the reason for your peevish reply...

This string was moribund since june and suddenly its a thing?

FYI I chose the most aggressive stance, no email at all.
I use the web and I get to see it all.... even that the message before this is from June 7!

If using flash, put what has been EEPROM data into RAM, make any changes there for current operating mode.
Have an explicit "SAVE" command to store from RAM to flash, establishing how it boots up.
Flash is typically good for 100,000 erase/write cycles, that's an awful lot of "SAVE" commands.

Ideally also have a backup flash sector, and "SAVE-TO-BACKUP", "READ-FROM-BACKUP" commands.
Will need that when your cat steps on the power button while you're doing a "SAVE",

Hi Hylton,

Each user may control their own email/attachment preferences.? Just click the "Subscription" link on the left menu, then click on the drop-down arrow for "Advanced Preferences".? In this section, you can choose your attachment size limit to receive, or even set it to zero bytes.? Then the attachments will only appear as downloadable links.

Cheers and 73,


Mark

Mark,

Generally space is not the issue, though its just being courteous.
I've seen way too many fuzzy and other marginally useful
pictures.? That prompted my comment.

And a side note,

JPEG has excellent compression methods; a file compressed at a quality level of 60 will still look excellent but will save 3-4x the space and download faster.

Size as the mega is only the older uno size board...

Price is not the issue usually as people are hanging expensive
displays and what not.

For a lot of stuff the Nano EVery was a solver for me as it fit the footprint.
Less EEprom for the aps i do it not an issue.

If the number of write cycles are low I think flash can be used as well.

Allison,

I had wondered that too. Must be one or more of price/size/heat/power issue?

I will combine two comments.

Since the mod manual will be likely electronic, the size of the images relative
to the page is not as important as resolution.? ?That makes it easy to bring up
the page and seriously enlarge it for detail on the screen.

That means lots of photos, at high resolution, and most importantly in focus for
the area of the board discussed.? Enlarged and fuzzy is not useful.

Further the result should have updated legible schematics.

What's interesting is the Arduino mega was passed over
completely. With more IO and 250K of flash,more ram and
EEprom yet for work that otherwise fits the 8bit realm it
was passed.

Not knocking the 32bitters but they eat flash faster,
and Eeprom is likely external anyway.? The got used because
they were ubiquitous or cheap.? For DSP or dsp like work
they are a better for for the math needed.

The Nano Every, gets some of that at the cost of EEprom
but its easy to add externally if it were really needed.

In the final MOD doc would you please make the photos full page.

will give the encoder software a try in the Pico version. Will let you know how it works.?

I get why Dr Lee pushed so much functionality off onto the Nextion. He was trying to squeeze as much as possible into that poor nano.

I am hoping that with the newer processors we can reduce the lioad on the Nextion making the maintenance of those screens?much more doable (and perhaps supporting dumb lcds too). So will definetly take a look at how you did things in the future.?

础诲诲别苍诲耻尘…

This one has been tested in a v6 and it fits (best not to include the lcd socket).?

Have not tried to fit the one with the external i2c connection into a v6 so there could be mechanical issues.?

Yes, the software and voltage are the real issues. You might also worry about the pull-up voltage on the i2c bus.?

I have actually designed a Raduino board that could take nano,nano every, nano IoT, nano ble and the rp2040. See gitHub.com/aj6cu. ?I have a jumper for 5v vs 3.3 and another set for the Nextion display d8/d9 vs rx1/tx1.?

?

The main challenge is the software. The software serial library is a problem (the teeny serial provided by kd8cec doesn’t compile and at least one of those platforms doesn’t support the real software serial) so I moved the Nextion connection to hardware serial 1 with the required pin changes.?

Also the kd8cec uBITX memory manager doesn’t work with the rp2060. So I am rewriting it…
