"Frequency selection is very straight forward. Use L1 variable coil to tune to the lower or upper frequencies that you want to receive and then use just
100K potentiometer to fine tune to any specific frequency. Potentiometer doesn't have to be mounted on the PCB. You can conveniently mount it on enclosure and use leads to connect it to the PCB. If you intend to use TDA7000 as regular 88 - 108MHz FM receiver the recommended voltage supply is
4.5 - 5V."
Chcê to sterowaæ przec uC ¿eby mo¿na by³o pokazywaæ czêstotliwo¶æ na wy¶wietlaczu... Czy dobrze rozumiem ¿e mo¿na raz ustawiæ sobie L1 i po¼niej rególowaæ czêstotliwo¶æ potencjometrem? Czy nie da³oby siê wiêc zrealizowaæ tego na ds1802 ?
Jak ¼le my¶lê to podpowiedzcie jak inaczej to mo¿na zrobiæ... :)
Ps. Chodzi mi oczywi¶cie o zakres FM...
