Subject: Configuration of MAX7301
Date: Thu, 3 Mar 2011 05:57:28 -0500 [thread overview]
Message-ID: <AANLkTi=y=5Xs1GJVsMjxH-js6pDTn37844NNAGK2oM1t@mail.gmail.com> (raw)
Hi,
I am trying to interface the MAX7301 IC with my Samsung S3C2440 processor.
The problem is the S3c supports only 8 bit word length for SPI transfer,
whereas my MAX requires 16 bit word length.
I couldn't find any info on the datasheet to use the IC on a 8 bit word
length. can i make the max7301_write function,
static int max7301_write(struct spi_device *spi, unsigned int reg, unsigned
int val)
{
u8 command = reg & 0x7F;
u8 data = val & 0xFF;
spi_write(spi, (const u8*)&command, sizeof(command));
spi_write(spi, (const u8*)&data, sizeof(data));
return 0;
}
Will this make the IC work? Please share your ideas.
--
Regards
Vikram
