Q: can USB-UARTS really manage that 0.1ms inter-char spacing ??. There are many buffers in play here.. plus the 1ms USB quanta effects. Seem more optimistic than realistic ?

 

I guess it would depend on how you feed it, wouldn't it?

 

The Python code seems to be attempting to space the bytes 100us apart, which is what is fed into the channel.

My point is the USB buffers and USB packet quanta, will not keep anything like 100us byte spacing.

The average data rate can be paced (assuming Python can deliver a 0.1ms delay), but the buffering means there is no guarantee of 100us between each byte.

Anyone got a Tiny817 + Python, who can comment out that delay and check operation ?

[without doing any research] I'd think that if my AVR fed my FT232R a continuous "packet" of bytes that the FT wouldn't send each individually 1ms apart. 

Well yes, however that's going in the other direction. The FS USB frame is 1ms, and the PC will read multiple bytes in that time, if they are waiting. The highest FS USB UART speed in theory, is around 9MBd (12MBd-overhead)

HS USB has a 125us frame (and larger buffers)

Still seem to be some supply issues, but I think I can get the various bits without waiting with a combination of suppliers.
Mouser did sell all of their stock of tiny817; Mouser has placed orders for 2 reels of tiny817 (both temperature ratings) with an ETA of about one month from now.

In the meantime, microchipDIRECT has 3 reels of tiny817 125C with a low minimum (25) plus the partial reel fee.

tiny1617 - microchipDIRECT has more than 3 reels (low minimum, partial reel fee)

Surprised that microchipDIRECT sold all their stock of the full kit; it has a one three month lead.

Surely the clearing out of the ICE was intentional. They sold off at a discount so they can fill up with a new batch where the housing does not say "Atmel"..

It is quite plausible that the "ibdly" inter-char spacing is a relic from early debugging, or from before the correct two stop-bits configuration was in place.  UPDI can handle a much tighter byte-stream.

Did jump out at me...

Did you confirm removing it ? Does removing it give a useful speed gain on larger downloads ?

I think the half duplex is managed by the data blocks, as the host knows when the remote will reply.

All of those are

except for the

- Secure AVR BLE IoT Node Field Engagement Board

 


Introduction
============

This example demonstrates an AVR IoT node powered by ATtiny1617 and secured by
ATECC508A. RN4871 BLE module is also equipped on this kit to enable the
connectivity. The kit is battery powered and can be connected to smart phone
app via BLE at any time. The main MCU and BLE module are featured with low
power operation and fast wakeup response, the end customer will not notice
the difference between sleep mode operation and active mode operation. Open
the phone app, discover the node and connect it in one go. All the
authentication and connectivity functions run in background.

- Secure AVR BLE IoT Node with ATtiny1617

Supported evaluation kits
------------------------

- Secure AVR BLE IoT Node Field Engagement Board

Running the demo
----------------
1. Press Download Pack and save the .atzip file.
2. Import .atzip file into Atmel Studio 7, File->Import->Atmel Start Project.
3. Build and flash onto field engagement board.
4. Open phone app "Secure AVR BLE IoT Node" and connect to the selected node.
5. If passing node authentication, it will show the range between phone and node on the first page.
6. Swiping left, the second page shows the temperature log from the node.
7. Swiping left to the last page, it shows the tri-axial acceleration data from the node.

hehe, I wonder how does a change to the document only result in To Improve Manufacturability  ?

 

Has anyone seen which packages are offered for the Atiny32xx series yet ?

Simple, if a bit of the silicon doesn't work then you remove any reference to that function is the datasheet...... devil

Ahh yes, I've seen exactly that in action..... done by Philips for their CMOS Logic, when we reported some test values with a query.

Surprised that microchipDIRECT sold all their stock of the full kit; it has a one month lead.

In stock but very low quantity and the lead time is now nearly three months.

I'm concerned that tiny1614 will not stay in stock at microchipDIRECT for long.

Reasons :

  • tiny1617 was briefly available
  • distributors will become aware of tiny1614
  • Microchip's "Letter to our clients"
  • no hints of a tiny1617 Xplained Mini
  • tiny1614 is a match for 1.27mm pitch protoboard

I'm seeking interest in a group buy of tiny1614 before it goes out of stock.

No commitment in this thread.

Commitment occurs after I buy a snippet of a reel of tiny1614, create the group buy thread in Marketplace, then appear before a postmaster per your order.

Risk to me is due to minimum quantity, partial reel fee, unsold tiny1614, value for it's at cost, USPS vagaries, and currency conversion.

Risk to you is due to value (tiny1614, postage, package, any USPS delivery assurance); no minimum quantity with payment "in the mail" shortly after successful delivery.

 

If interested, please answer :

  • Are you in?  Yes, indeterminate, or unknown1
  • If yes, what quantity of tiny1614-SSFR?  Less than 100 for I'm not a distributor (I'm a third party of lesser relative means)

Thank you for considering this.
