tacq=2Tad, Tad=2*Tosc (or Fosc/2) sinon je pense a sa
-----

[antek]

C'est écrit dans la doc et ça dépend entre autres de la résistance de source.
Avec ton schéma il faut au moins 50 µs

[invite2fd0e04b]

101 = 12 Tad
et en ADCS2:ADCS0 101 = FOsc/64
je pense ke les reglage sont la ou je je me plante ??

Ce que tu montres est le choix de l'horloge du CAN.
Tacq est une durée : temps entre ADC_ON et ADC_GO, c'est à toi de le réaliser dans le programme.

bonsoir,


Je ne pense pas que le probleme soit principalement sur le choix de TAD .....
2 tests realisés avec un 16F1847 ,
un à 8MHZ et choix TAD Fosc/16 ( OK dans le tableau)
un à 1Mhz et choix TAD avec FOSC/64 (Non preconisé dans le tableau)
dans les 2 cas il n'y a aucun probleme pour detecter une mesure depassant 512 point,
seuil pilotant la sortie led .
.
Test en reel et non pas en simulation .
J'ai utilisé un potar de 22K (lineaire).. pour simuler le diviseur R10K +CTN10K
Le seuil est bien situé autour de la position milieu du potar..
C'est d'ailleur un moyen bien plus fiable de tester ce bout de programme..

Le bit fin de conversion bascule bien APRES tous les TAD necessaires , si j'en crois ce tableau ?
La condition à verifier est que la division de FOSC , via la config des bits ADCS1 ADCS0 soit dans une zone valide
dans le tableau.. Apres si on choisi une frequence trop basse.. la mesure dure plus longtemps,
et peu éventuellement presenter une legere instabilité...



Il me semble qu'il doit aussi exister une delay minimum entre chaque (mesure) relance de conversion ADC.
Dans l'exemple ci dessous , A 8Mhz il y a >38µS entre chaque mesure (SANS ACTIVER la sortie sur UART ).

bonjour,

il n'y a aucun probleme avec TAD ou FOSC ....
j'ai pu testé aussi sur un 18F2550 que j'ai sur un module MikcrorE Startup USB kit 2550
test fait avec 1MHz Fosc interne
meme Tad=12 et FOSC/64
entree ANA sur RA0
mais LEDpin sur RA1 !


Au fait, tu fais comment pour relier ta led LEDpin sur le port D avec un 18F2550 ?
dans le monde reel , bien sur..
