please help us;
we area trying to spi interface b/w 1176 with 7462 nfc reader , i checked with logic analyzer it will not generating any signals . help us to how to configure and send data,
how to change the wakeup mode , the default we press "F8" it will debug, i wants to change spi intrupt to wake up and data to sent and receive in spi only , in this case it prints the data in console we wants to prints the data in terminal how to change it ...
thankyou.......
