I’m using a dw1000 with tcxo. After entering the deepsleep I turn the txco osc (on pic: PB7) off and vddbatt are not anymore on high level too. On wake up i need a complete new init of dw1000 to tx and rx again. What i’m doing wrong? Can i use the deepsleep with an tcxo or I can’t? Is there a problem when the vddbatt is low on deepsleep?
Enter sleep mode code:
dwt_configuresleep( DWT_PRESRV_SLEEP | DWT_CONFIG , DWT_WAKE_CS | DWT_SLP_EN ); dwt_entersleep(); /* then turn off txco (PB7)*/ .... /** then turn on txco (PB7)*/ dwt_wakeup(); /* complete new init of dw1000 needed? why? */
