Guest Xcen Posted June 17, 2003 Report Posted June 17, 2003 Hi!Yay! Just received my Core PCB (thanks again Smash!)I am going to order some samples to build my first MB.I am wondering, for MIOS (future project) what chip is needed?PIC18F452-I/ML; PIC18F452-I/P; PIC18F452-I/PT; PIC18LF452-I/L; PIC18LF452-I/P; PIC18LF452-I/PTFor the MB64: PIC16F877-20? (Not available as free sample?)And finally, for the BankStick chip: ? (Heard you could get those as well but I'm not sure...)Anything else I should get?TIA! Quote
jeroddumas Posted June 17, 2003 Report Posted June 17, 2003 Youb need the 18f452 i/p. Ordered those from the sample site also. hmmm wonder if my 40 days are up so i can order some banksticks ;D ;D ;D Quote
smashtv Posted June 17, 2003 Report Posted June 17, 2003 Just received my Core PCB (thanks again Smash!)I can't take any credit for that, I merely passed them on in behalf of a very cool Midiboxer. :)Have Fun!SmashTV Quote
basta73 Posted June 17, 2003 Report Posted June 17, 2003 18F452 I/P is definitely it, The banksticks I got were the 24LC256I/P, and I also got the 24LC512I/P, cause you never know what the future may bring. Quote
Guest Xcen Posted June 17, 2003 Report Posted June 17, 2003 Nice! Thank you :)Any info on the 16f for the mb64? There is the 16f877A that seems available as a sample, would that do?Smash: you're right so here is the correction:Thanks anonymous MBer for the cool gift and thanks Smash for all the rest :) Quote
Guest Xcen Posted June 19, 2003 Report Posted June 19, 2003 Bump! (Just to make sure no one knows :P ) Quote
Guest Xcen Posted June 21, 2003 Report Posted June 21, 2003 I don't mean to be annoying but could some1 clear up this question for me? :)Any info on the 16f for the mb64? There is the 16f877A that seems available as a sample, would that do? Quote
Guest HiM Posted June 21, 2003 Report Posted June 21, 2003 How or indeed where do you get these free samples? Quote
Guest Xcen Posted June 21, 2003 Report Posted June 21, 2003 Hi there!microchip is giving free sample pics... you can get them on their website at http://sample.microchip.com/I was just asking about if I could use 16f877A instead of PIC16F877-20... otherwise I'll just buy a 16f877a! Quote
TK. Posted June 22, 2003 Report Posted June 22, 2003 Yes, the PIC16F877A is working, you only have to take care with the JDM programmer. This chip has a special setup, and you need to increase the IO delay to 20 in order to lower the programming voltage.Best Regards, Thorsten. Quote
Guest Xcen Posted June 22, 2003 Report Posted June 22, 2003 ok so I just need to build/configure the JDM module differently?Will that affect performances in any way?Thanks! :) this project is getting me very excited but I don't know that much about electronics :) Quote
Steven_C Posted June 22, 2003 Report Posted June 22, 2003 JDM stays the same. IO delay is a menu option in IC prog Quote
Guest Xcen Posted June 22, 2003 Report Posted June 22, 2003 OK nothing else will change right?I'm gonna place the order today!I'm also trying to scavenge a DIP housing from an old motherboard for my pic :) Unsoldering is harder than I thought heheheEDIT: ACK! Is it the pf16f877a-I/P or pf16Lf877a-I/PI'd say the first one but I want to be sure (can't understand the difference between the two)I should be done asking questions about that after this one :) Quote
Guest Steve_C Posted June 23, 2003 Report Posted June 23, 2003 why don't you just order the regular pic16f877-20 (20 means 20 mhz, make sure you order a 40 pin version, P and I/P just refer to the temperature range, I/P is for hotter environments I think. Both will work in a midibox) from microchip? Order a pic18f452 while you are at it, for future upgrades. (and a bankstick chip) Even though you will wait for your free sample, you will be building the rest of it while you wait anyway. Quote
Guest Xcen Posted June 23, 2003 Report Posted June 23, 2003 Thanks for those additional details, it really helps :)As for the 16f877-20 it wasnt available as a free sample so that's why I took the other... I could've ordered it but I'm not really good in electronics so I prefer to "practice" on free chips :) I got some banksticks as well as the 18f too :) Quote
Guest Flownezz Posted June 24, 2003 Report Posted June 24, 2003 Microchip stopped shipping to australia :'(. Quote
stryd_one Posted June 24, 2003 Report Posted June 24, 2003 Yeh when I start making synths professionally, you know who's products I WON'T be using!Bastards... I saw their logo on a champcar race last night... For the price of that Ad they could have shipped enough PIC's to bury me alive!!!Still that 18F is pretty impressive ;D Quote
reincarnate Posted June 24, 2003 Report Posted June 24, 2003 I got my samples from Microchip after 2 weeks, even though they said 4 months, so worth going for even if you think your box will be finished by the time they arrive. Quote
Steven_C Posted June 24, 2003 Report Posted June 24, 2003 I got a free sample... including pic16f877-20, and I live in Australia, that was about 2-3 months ago max.... There is a microchip office in Epping, Sydney. (though I ordered from the website, took 2 months to arrive!!) Quote
