Subject: MAX1236 with smbus (CS5536 ACB0)
Date: Mon, 13 Oct 2008 03:20:48 +0200 [thread overview]
Message-ID: <48F2A270.8060307@leipzig.freifunk.net> (raw)
I want to connect a MAX1236 (ADC) [1] to a I2C/SMBus in a
PC-Engines/ALIX board to monitor some voltages.
This board have a AMD geode CPU with an an I2C companion (scx200_acb.c).

but i cant access the MAX1236 on slave address 0x34.
(0x4c is the onbard LM90)
Does "I2C no" means the CS5536 is a plain smbus without i2c support?
Regards
Andreas
