#163995 - MY FINDINGS AND HARDWARE CONFIG Responding to: ???'s previous message |
ACCORDING TO DATA SHEET, I HAVEN'T EXCHANGED MOSI AND MISO PIN ,AND ACCORDING TO MY HARDWARE CONFIGURATION,I AM USING FIRST PIN OF PORT1 AS CHIP SELECT.5TH PIN OF PORT1 AS MOSI PIN,6TH PIN AS MISO ,7TH PIN AS CLK.
NOW,I AM RECIEVING WAVEFORM ON MOSI PIN DURING READ AND WRITE CYCLE,GETTING CLK ALSO,BUT NOTHING APPEARS DURING READ CYCLE ON MISO , I AM FEELING MIGHT BE I AM SENDING START BIT ,OPCODE AND THEN ADDRESS IN WRONG WAY. AS THERE ARE TOTAL 9 BITS TO BE SEND INCLUDING START BIT(1),OPCODE(2) AAND ADRESS(6). I AM SENDING INSTRUCTION IN TWO BYTES.fIRST,I AM SENDING FIRST BYTE AS 0000000SB,AND SECOND BYTE AS OP1OP0A5A4A3A2A1A0,IS THIS IS THE CORRECT WAY TRO DO SO?I AM FEELING MIGHT BE I AM WRONG IN THIS THING |
