AVR128DA support?

Hi,

is there any chance that the new AVR128DA familiy will be supported by Bascom?

(BASCOM-AVR version : 2.0.8.2 )

I certainly hope so!

They are the "new and improved" AVR's, incorporating many of the features that were originally brought out in the Xmega series.

They also come in both surface mount and PDIP formats, so they are easy for anybody to use.

This requires a lot of work and I think this qualifies for extra charges. Like after so manny years pay full again.

Best regards

it depends on how much interest there is in the xtiny add on.
and of course in this new series.
i did not see PDIP but maybe i overlooked something.

The problem with xtiny was that i started with preliminary docs which changed a couple of times. some casings were removed.

edit : oeps, overlooked it.

Hi Mark,

I believe the PDIP version exists, which I think has usually been of interest to Bascom.

Check you Support eMail, I sent you an eMail a while back offering to send you a few AVR128DA48's to work with, if you so desire.

Take care,

JC

Mouser in Austria offers it at a price of 1.95 Euro at 25 pieces and over 600 in stock.
I am sure most other Electronic Companies do offer it also.

The question is, what is the correct programmer unit for it and will Bascom support it.
Atmel's Studio ver.7 not, maybe they will come out with a new version.

Best regards

Having had a read through the spec sheet this AVR has two very useful parts
for power monitoring or generation.
A 12bit ADC
A zero crossing detector

I can see this in a lot of diy power monitoring projects

It has a lot of other nice features like the xmega

I like the two level interrupt.
With that you can make the free running ADC some kind of sytem clock that allways has priority.
And 'weave' dynamic calculated timer actions around that.
I have setup something with Atmega1284 to accurately control the timer in a proces that measures the time constants.
Hopefully to be used as a position sensor("-less") actuated solenoid.
There are workarounds to make sure that ADC allways has priority with traditional AVR's like Atmega1284, but the two level interrupt makes it easier.

On the other hand, except for the PDIP and 5V, what would be the benefit over the 32Mhz and ISP-programmable Xmega? Xmega32E5 costs €2...€2,50.
Is it (really) less complex? Why isn't it 32Mhz, should we expect a better but again different version...?

These look great to me. 28pin PDIP with 24 MHz clk., 12bit ADC and a DAC! I hope Mark adds this one to the list. It would have been even better if they had made it pin compatible with Atmega328 so I could upgrade old hardware but that is asking to much.

Offer with proper working UPDI programmer will help to sell Bascom upgrade.

Yes, I also blocked several 1616 errors in the macro before I came to the conclusion that by default they have the fuses set to 0, which shuts down UPDI. From this state it is possible to get a 12V programmer. Just after resetting the processor, send a 12V pulse to the UPDI pin and the processor will enter the programming mode.
I assume that Bascom works with UPDI as well as with other programmers and reads the fuses from the circuit, so unintentional overwriting should not occur. I haven't tried it in Bascom yet, but I'll soon try as soon as the expansion from Mark arrives and I'll have some time.

To olhexy
Yes, the UPDI interface should also work on a virtual com from Bascom. Mark writes it in his post.

Mark:only downside of updi is that it is shared with RESET line on most chips. This means you can not have reset since updi is default. ok you can program it, but then the updi is gone.

Starting UPDI is false on txd. Due to interference, it is better for the application to have UPDI turned off. In case of accidental start-up, the current consumption is up to 2mA. This is important for battery operation in a low power application.
You can use this https://www.tindie.com/products/leonerd/avr-updi-programmer-with-12v/
(I invented it a little differently last year, mainly I didn't let 12V into the input of the converter)
In the data sheet, for example attiny1614 page 472, it is described what the pulse should look like when communication starts.
If Mark ever has time, he may add this option to the programmer. I personally switch PD0 to RESET, I had problems with current consumption as I wrote above.
