I would like to display the value, which is read from register on my computer screen. int init_spi_read(void) /* Data is being read from SPI, MISO */ { char read; read = S0SPDR; while (!(S0SPSR & 0x08)); /* check for the SPIF bit */ return (S0SPSR); /* if Bit is High, read status register*/ printf("The data read from ADC is %c", read); } when compile no error but when I want to read value from hyperterminal com...it doesn't display.....where am I doing error ??? Thanks.... Sridhar.
