They probably realised that what THEY think is a "popular feature" is something that no one cares about ...  we'll see. |

It's a vaporannouncement?
I wonder if someone jumped the gun in announcing the announcement.
Atmel's press release page shows "integrating LCD controller into popular AVR XMEGA Family" on the 21st. Is that a "popular feature"?! (if so, maybe AVRFreaks is the wrong audience). |

I believe it's the new XMEGA B series, which has been in development for quite a while. Yes it has an integrated LCD controller which not all the hobbyists will care about (but large manufacturers of thermostat controls and so forth will) but the headliner is the *lack* of capabilities; they're essentially ATXTINY. Hopefully the prices will reflect that.

| So an Xmega169?? Will we now get X-Butterflies to play with? |

| It is also first XMEGA in TQFP-100 package (lots of GPIOs) with USB and fixed ADCs. |

Yes, but a bunch of those pins are dedicated to LCD segment control so I'm not sure you actually get more GPIO than with smaller devices.

Now I'm neither in the industrial production or having any experience on the mega169, but since I recently received a minor quantity of some 4cm tall 5digits LCDs this Xmega B-series suits my current need perfect.
I'm working on a micro amp meter, which just uses the internal ADC of an Xmega. It should give a resolution about 25micro amps between 0-5A. But since the LCD has 40 segments it's quite a few I/Os being used.
With the new B-series drivers for the LCD are ready to be used. It even has a true USB for logging purpose instead of using additional level converters and USB/serial converters.
If you want to read more on my progress more can be read on here: http://nerdclub.dk/2011/10/micro-ampere-meter/ <-- It's in danish but google translate does a good job.
For version 2 I've just purchased the Butterfly successor: XMEGA-B1 Xplained |

Can any one confirmed the ADC bug fixes?!?! Atmel did not mention them on the product release.
Also, where can I get a schematic/reference design for these XMEGA-B1 Xplained boards?
Thanks guys |

Hi Mario.
My experience with schematics is that Atmel will give it away as soon as someone is asking for it.
But with such a new board I'll guess an update for AVR Studio 5 together with ASF will be release within few days.
If not I'll get a board within 5-7 days which is not supported with drivers  |

Unless you own an STK600  |

Thanks simon
I just hope they fixed the ADC bug fixes on this one. |

Me to, since I need an precise ADC on each bit.
Anyway. I've wrote Atmel support, and post whatever answer I'll get. |

I ended up ordering the board before they're gone. $48 total after $20 shipping -ouch!
I checked the errata section and did not notice anything relating to ADC. It's fairly recent (10/11/11), so I'm assuming ADC bugs are squatted.
I'm not sure what Dean meant with his comment about these parts being essentially "ATXTINY."
After reading the datasheet the only thing lacking was a dedicated DAC. These parts do have less timers, usarts, SPI, and I2C's. Otherwise, they include the standard features of other xmegas plus the USB and fixed ADC.
Why are people saying that "LCD" feature are not popular with hobbiest? |

Did you not read the other thread (from about here onwards):

It's a segmented glass controller. When's the last time (in 5 years say?) that a hoobyist ever bothered with segmented glass when they can just use an HD44780 type character display or a KS0108/T6963 GLCD? I suppose the segment controller is fine if you want to make a 3.5 digit DVM or something? But most people want to write "Hello World" as a bare minimum. |

haha 20$ shipping. You must be close to the shipping central!
I ordered this + 2 other xplain boards and they wanted 33$ shipping.
With a 99$ voucher and a own payment on 13$ the shipping cost was fairly large percentage of the total amount.
And regarding the LCD controller I totally agree with Clawson.
I too would not have had any interest in this uC if I didn't had a lot LCDs laying around waiting to be used. I would prefer the T6963C LCDs since they can do both graphics and text |

Ok, basically half DMA channels (2 vs 4), but the controller on these newer xmegas seems to be improved. Also half the event channels (4 vs 8) with no improvements (exception of USB triggers). It seems like it is indeed missing EBI (external bus interface), but to be honest, most people don't used it anyways - GPIOs are the preferred method to interface with srams, flash etc.
But you're right about the integrated LCD controller, why create such a mediocre controller?!? Even the AVR butterfly has a better controller. Why not upgrade instead of downgrade? It seems like Atmel should have integrated the controller from the butterfly and not do a segmented controller.
Oh well, at least I can still use 16 of those LCD pins for GPIO -wait the XmegaB1 Xplained doesn't bring out port g or port m (nooo!).
So is life |
