مشکل با ماژول RFM12b

سلام، من چندتا ماژول RFM12b خریدم ولی هنوز نتونستم باهاشون اطلاعاتی ارسال و دریافت کنم
مدارم رو با 3.3 ولت بستم
اینم کدهام:

فکر میکنم نمونه کد آماده برای سند و رسیو با RFM12 دارم اگه پیدا کردم قرار میدم

فقط مطمئنید ماژول با 3.3 درایو میشه ؟

با عرض پوزش برنامه برای send receive با pt2262-72 بود ! تنها PCB های مربوط به RFM12 موجود بود !

ببخشید کار با pt2262-72 چطوری هست؟دیتا هم میشه باهاش جابجا کرد؟ تا چه فاصله ای؟ ممنون
