naprogramovanie ATmega164A

[fagi]

tdravím

potrebuje si naprogramovat tento mikroprocesor no a používam AVR8-Burn-O_ma a programator http://www.fischl.de/usbasp/
normálne som si nastavil v menu tento mikroprocesor a ako prve som chcel prečítat fuse ako su nastaven no nejde mi ich prečítat Burn o mat napíše toto :
avrdude.exe: AVR Part "m164" not found.

skušal som aj slov sck na programatore ale no nepomohlo

mal by som stiahnut novšiu verziu Burn-O _Mat alebo čo hmm ?

[Tribec Zacks]

ak nemas analyzer, skus dat ledky cez rezistor na sck a data a nejaky pomaly clock speed, mali by prebliknut ked chces detekovat alebo programovat mcu, zistis tym ci ten programmer chce nieco s mcu robit. ak nemas externy krystal na mcu a ten bol predtym naprogramovany na externy krystal, tak ho musis pripojit. a hlavne skontroluj vsetky prepojenia poriadne. a jj stiahni novsiu verziu, najlepsie aj niekde v release note pozret podporu mcu a bugy.

[dan21]

pozri ci ma AVR8-Burn-O_ma v konfiguracnom subore podporu pre m164. Avrdude ma config kde to mas definovane
Vyzera to ze tvoj soft nepozna (nema definovane) m164

v tom config subore bolo napísane toto :

[dan21]

takze skus pouzit m164p

[fagi]

no a jak ?

[Tribec Zacks]

V klude prepis ID v tom konfiguraku na 'm164'

[dan21]

V tomto ti neporadim, kedze AVR8-Burn-O_ma nepouzivam a ani nepoznam

[fagi]

no prepísal som to na configu na 'm164'
a začalo sa diat toto:


avrdude.exe: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.02s

avrdude.exe: Device signature = 0x1e940f
avrdude.exe: Expected signature for ATMEGA164P is 1E 94 0A
Double check chip, or use -F to override this check.

avrdude.exe done. Thank you.




či som mal všade prepísat to na m164 ?

[Tribec Zacks]

Vypada to ze budes muset poguglit presny konfig pre tvoj mcu do avrdude, neviem ake su presne rozdiely medzi "164" a "164p", ale ak nepouzivas nic specificke co je medzi nimy rozdielne, tak by ti program mal fungovat, pridaj flag -F k spustaniu avrdude. Flashnut ti to flashne a malo by to ist, ale nerucim ti to, ak su rozdiely v poistkach, alebo v niecom podobnom tak tam je riziko ze nieco nepojde.

[fagi]

a ako tam dam to -F ?

[dan21]

alebo v konfiguraku skopiruj celu definiciu m164. Prepis meno, signature ..........

[fagi]

dobre prepísal som v configu na signaturu už mi to ide a ide to na vnutornom RC oscilatore a teraž chcem nastavit na externý 16MHZ kryštal tak by som mal dat takto ?

[dan21]

http://www.engbedded.com/fusecalc/

[fagi]

možem sa spytat načo je tento bit ? CKDIV8 čo tým nastavím ? to ako ked mam tam 16MHZ on mi predeli frekvenciu 8 ? väčšínou robim s megami 16 a 32 a tam daco take nieje ?

Clock divide by 8. Ano, vydeli 8.

[fagi]

takže ked dam 16MH kryštal tak mi pojde na 2Mhz aj CPU aj periferie taže nema byt zašktrnuty dobre?

[Tribec Zacks]

16/8 = 2. <- co vsetko je clocknute tymi 2MHz sa docitas v datasheete, ale ano aj periferie u avr.

to ci ma byt zaskrtnuty, alebo nie, zalezi na tebe. ak potrebujes 16MHz, tak nema byt zaskrtnuty. ak ti netreba rychlost a potrebujes optimalizovat na spotrebu, tak to je jedna z moznosti ako ju znizit..

[fagi]

cudný priebeh ,aj ked retenem to ta tak to zostane

este mam takú záhadu

som skušal napísal daco robit s casovacmi generovanie pwm no ale nefungovalo mi to ale vo while(1) mam taku cast programu čím kontrolujem ci to sa dakde mi nezacyklilo
nakoniec som ten program očesal až na to ninimum že to len akoby" bliká s ledkou" som tento program :


#define F_CPU 16000000UL
#include <avr/interrupt.h>
#include <avr/io.h>

int main(void)
{
DDRA |= (1 << PA0); //output pin

while(1)
{

PORTA |= (1<<PA0);
for(int i=0;i<4000;i++){}
PORTA &= ~(1<<PA0);
for(int i=0;i<4000;i++){}


}
}

proste obycajne blikanie no na osciloskope mi toto zobrazí niečo akokeby sa tam prerušovalo a ani resetom sa to nezmení ale až odpojením a pripojením programatora, zaujímave že je to dost taký nepredvídatelný problem, a neviem si vysvetlit čo ho spôsobuje

[Tribec Zacks]

mas dobry pullup na resete? s pripojenym programmerom ti to moze robit sarapatu, zalezi co je v programmeri..
