Out of interests sake, what version of Optiboot is this bootloader?

Just been reading the "ATmega1284P: End to End using 1.0 IDE " thread.

Cheers

Ok thats fine, thanks.

Ill give it a try

Hi again...

Is that pins_arduino.h file correct?
It looks to be the TH version with 40 pins... the SMT version has 44 pins.

Thanks

You are the man, thank you very much.

My PCB will be arriving tomorrow, so I will text it as soon as its built, no doubt the same day it arrives, and let you know.

again, thanks heaps

Awesome thank you!
Can you please recompile it to use UART0?
That would be amazing.
Much appreciated.

You are using the smt part right?
What core are you using?

Thanks

Hello,

Yes, lots of 1284P chats going on at the moment.

I havent yet found a 1284P-AU (SMT Package) bootloader though for 20Mhz. Just wondering if anyone knows of one?

CrossRoads suggested the mighty1284 bootloader, https://github.com/maniacbug/mighty-1284p, but I believe this only goes to 16Mhz and if changing it to 20Mhz then millis() and micros() will be off etc.
Its been many months since I have played with these things, but rusty. Having to catch up.

If anyone knows of anything suitable, can you post a reply.

Thanks

Hi,

I was just curious if you are planning to upgrade this library to Arduino 1.0?

Hi there,

Sadly no, too many other things on the cards, havent had a chance to get back to this yet.

Haha - awesome smiley

Currently reading a high speed input from my Frequency Generator of 1.3Mhz (1.32790Mhz actually) smiley
Thats as high as I can produce with this generator.
Dont know if the freq generator is the accurate one or if The Brick is the accurate one, but they are reading very close.
The Brick is reading 1328437 and the Freq Generator is 1327902, which is a difference of 535Hz at that range, about a 0.0004% difference smiley-cool

I think I can live with that.

Logging it to SD Card, displaying it on the LCD and transmitting it over Bluetooth to the Laptop - not bad, not bad smiley

Playing around with the RTC and an LCD, thought I would take a snap.

Just created a multi-tabbed program to test out all the features of the board, which is running on it at the moment.
Still far from perfect but getting there.

Hi Tony

Sure have. Just need to get these prototypes tested to iron out any problems that may exist - I havent found any yet on the functionality, but have identified a few improvements I want to make (only minor things).

But yes, I would like to offer this for sale - that is the plan. I have a company in Australia potentially interested, so I will be sending them my prototype once I have it built and have a program in it, so they can have a look/play. I have a smaller version of this designed on paper too called the Brickette, which features an inbuild 4D Systems uLCD-32PT display in the case. Picture attached. But that one wont be prototyped until The Brick is fully sorted etc.

I think these would be a good 'upgrade' for people on here who want to take their arduino to the next level and use it on a machiine etc, as the Arduino isnt really intended for final products - but can be obviously.

Open to suggestions at any stage.

Regards
James

Right,

Here is the first draft of the documentation if anyone is interested.

Still in progress.

Wow just did a count, there are 232 discrete components on The Brick.

25 IC's
53 Resistors
44 Capacitors
28 Diodes
45 Headers/Sockets of various sorts
+ the rest.

smiley-grin

Just for useless but interesting stats - ha.

Hi Liudr

Yeah sold 4 prototypes at cost price, just so I could actually get some built and tested.

HMI wise - well the Brick has facilities to plug in a character LCD and mount that into the case, or a 4D Systems touchscreen and mount that into the case. So in theory people could utilise your HMI with little effort, or use a 4.3" touch screen etc from 4D Systems, which has their own programming software - or use it in SGC mode and treat it like a standard graphics LCD and draw stuff on the screen with commands.

I will post a DRAFT version of the documentation I am working on for The Brick shortly. Note, it is still in Draft so may contain information with is wrong or incomplete.

Cheers
James
