SCK and SPI question ?
Yes I used fosc / 128 for setting up CLOCKF.... I changed to 0x6800....still the same ...produced "ting" "ting" "tuck" "tuck"....when I see at logic analyzer...it's sending the...

SCK and SPI question ?
I can hear "teng" ....."teng"....."teng" with this code : while (p <= &HelloMP3[sizeof(HelloMP3)-1]) { //loop_until_bit_is_set(VS1003B_PIN,VS1003B_DREQ...
