Why nothing changed after calling function TPMS_FLASH_ERASE() and TPMS_FLASH_WRITE() ?
What's wrong with code below ?
fosc = 8MHz, fbus = 4MHz
FCDIV = 21;
// Fclk = 4MHz / (21+1) = 181.18KHz - 150KHz~200KHz
//----------------------------------------------------------------------------------
const BYTE CParaAddr[] @ 0xD200u =
{
0x44, 0x55, 0x66, 0xff, 0xff, 0xff, 0xff, 0xff,
0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff,
0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff,
0xff, 0xff, 0xff, 0xff, 0xff, 0xff,
};
......
FCDIV = 21;
SendDebugContent(CParaAddr[0], CParaAddr[1], CParaAddr[2]); // receive data are { 44 55 66 }
mRfData1 = TPMS_FLASH_ERASE((WORD)CParaAddr); // the function return 0x00, ERASE succeed ?
mCommonBuffer[0] = 0x77;
mCommonBuffer[1] = 0x88;
mCommonBuffer[2] = 0x99;
TPMS_FLASH_WRITE((WORD)CParaAddr, &mCommonBuffer[0], 10);
SendDebugContent(CParaAddr[0], CParaAddr[1], CParaAddr[2]); // still { 44 55 66 } not { 77 88 99 }
why?
