И снова NRF24L01, Нет напруги на VDD_PA Опции

[viael]

Использую библиотеку с сайта нордика. Все регистры пишу согласно примерам. Все пишется и читается нормально( смотрю отладчиком ).
В режиме приема на ноге IEREF=1.2V на VDD_PA=0V. В режиме передачи и там и там по нулям.Соответственно ничего не принимает и не передает. Модули самодельные по мотивам референс дизайна. Может какие то тонкости есть...?

вот код

З.Ы. Перепаивал чипы на новые (из другой партии), но тот же эффект.

Вопрос закрыт. При инициализации надо очистить буфер приема и передачи.
