Hello people ,
we need some help from ST for solving the ST7538-Q interfacing with SPI .I don't even no where I have to ask the question .currently I am working in powerline communication using st7539-q and we are trying to communicate ST7538 -Q via SPI interface using this pins
RX( MOSI),
TX(MISO),
CLR/T(SCLK),
RxTx and REG_DATA for selecting the transmission (or) reception (or)control register read (or)control register write I can selecting using this pins (REG_DATA AND RxTx).....LIKE 00,01,10,11
TB= 417 Micro seconds
TCC=2*TB=834 Micro seconds
TCR=TB/4=104.25 Micro seconds
we are doing the as per the SPI clock diagram and and with this timing but we cant get nothing in the RX(MOSI)..Actually in datasheet they told if we do like SPI CLK DIAG we get some internal control register value but our mosi pin only on high nothing it will send.....
do you have a source code send it it will helpful for us
thank you
Plz give some response because we are struggling with in it .
