it's OK, we like to hear frome you every now and then to knwo all is well.

micro-

how about one of these ? digikey it had the same footprint but only one counter/ timer..

link is broken, but if I were to make to choose a new processor now it would be an Atmel ATmega48

summary datasheet for Atmega48
http://www.atmel.com/dyn/resources/p...ents/2545S.pdf

check out pages 18-21 for the different sizes available I'd stick to the 20Mhz chips since that's what the current chip is. the only thing left is to check digikey and see what the availability is because they only stock the common options... which is what we would want anyways.

These chips have several advantages first if I would ever run out of memory I can get the same chip with up to 16k of memory (8 times the current chip although 4k should be pleanty)

second they can be really tiny 5x5x1mm... much smaller than the current chip

and that's just to name a few physical details... there's a few programming advantages too.

try this digikey pdf


Attiny861v-10pu-nd

this processor has the same footprint for the boards it would make it easy ..

It looks like a good chip there are 2 things that concern me... the pinnout is different enough so that it could never be a drop in chip, and also it doesn't have as many IO pins. It has 16 instead of 18. That isn't really a problem though because currently only 13 of them are actually used.

This chip does have some of the advantages of the Mega48 too... the main one is that every IO pin is an interrupt. This means the gun could be put in sleep mode whenever you're not shooting and not kill yout battery... I actually wrote the code to do this before I realized that it would never work because the only interrupt is the trigger.

Here is a list of what i found when doing a pinnout of the Board. If anyone wants a full pinnout of the Microcontroller or a reverse engineered schematic on the board let me know and i'll either email it to you or post it if i get enough requests.

Port B
PB7 - N/C
PB6 - ACE
PB5 - Tournament Lock
PB4 - Display RS
PB3 - Display DATA IN
PB2 - Display CLOCK
PB1 - Low Voltage
PB0 - N/C

Port D
PD7 - N/C
PD6 - Display CE
PD5 - Bottom Button
PD4 - Top Button
PD3 - Solenoid/Warp Feed (at the same time)
PD2 - Trigger (HES)
PD1 - N/C
PD0 - N/C

Can someone double check these? I haven't gotten far enough in the code to use all of them yet and it would be extreemly frustrating if i had this part wrong. Send Me a PM and i'll edit my post so as not to confuse anyone who reads this later.

Paul ;
I cannot find a reference to pd7 on the chip diagram. Any thoughts ? Could you e-mail me the schematic of the board ?

Kayle

Yea guess I put that in there just to make things symmetric... In actuality you're right PD7 does not exist. The other one had 7 so I just made that one have 7 and left is as N/C. sorry for the confusion

[KayleAGD]

are there any pins that cannot be moved by programming ? other than VCC and GND

old AT90S2313 ...... new ATtiny861

PB7 - N/C
PB6 - ACE ...... PA2-PIN 18
PB5 - Tournament Lock ...... PA3- PIN 17
PB4 - Display RS ...... PB0- PIN 1
PB3 - Display DATA IN ...... PB1- PIN 2
PB2 - Display CLOCK ...... PA4- PIN 14
PB1 - Low Voltage ...... PA5- PIN 13
PB0 - N/C

Port D

PD6 - Display CE ...... PA6- PIN 12
PD5 - Bottom Button ...... PB6- PIN 9
PD4 - Top Button ...... PB5- PIN 8
PD3 - Solenoid/Warp Feed ...... PB4- PIN 7
PD2 - Trigger (HES) ...... PB4- PIN 4
PD1 - N/C
PD0 - N/C

I can make a crossover to move connections but the fewer the better. Better get youre programming fingers warmed up I think we can do this. Can you send me the diagram of the board ? That would save me alot of time ..

I'll send you what I got, but pm me your email again, can't seem to find it.

up

[LorneCash]

it's a clasic... I gotta bring it up

[zigss]

figured i'll try to help out the up post

Anyone know why Lorne's website is down and if the files are mirrored/archived anywhere? I bought the programmer more than a year ago, but never got around to flashing my gun. Also, any chance the programmer works with Vista?

Thanks,

Mine is an old serial programmer and it works perfectly with Vista. Don't know about the site but if Lorne doesn't mind I can get you a copy of 1.8. PM him first to make sure, ok?
