创维频率高频头的软件控制源代码，基于pic系列单片机-Skyworth frequency tuner control software source code, based on the pic series of single-chip

An RS232 port controls a TSA5512 via a PIC16F84 This allows a TV tuner to be scanned across its full range. 4MHz crystal for the PIC, the tuner has it s own internal crystal. Use a MAX232 for level shifting. SCL RB6 SDA RB5 Din RA1 Dout

国外AVR单片机驱动tuner原理图和源程序-I ve always liked real small chips like the Atmel 2323 and PIC 12C508. Despite their size, they contain some real power. The 2323, for instance, can be clocked at up to 10 MHz (and more if overclocked), and will perform at ab
