je continue à partager mon expérience sur le rf1100se / cc1101.
Apres avoir configuré les registres ca se comporte un peu mieux :
-le 1er senddata ne bloque plus mais me renvoie un failed
-le 2eme senddata bloque mais je crois que c'est le comportement normal a moins de modifier le bon flag
j'ai vérifié quelques registres en lecture, je retrouve bien mes valeurs passées en écriture, donc coté SPI tout va bien à priori.
Un module complexe mais qui offre plein d'options possibles.
Prochaine étape : un senddata avec succès
