How to use PCA9532 led dimmer with basic stamp???

Koco86

Hi everyone,
My english is not good.

I need use PCA9532 (http://www.semiconductors.philips.com/pip/PCA9532BS.html) to control some LED with with basic stamp. I have BS2p24-IC connected to PCA9532 via I2C bus and use "I2COUT " command in program code, but it not work... I'm in big stress, because I must finish this project tomorrow.

Please, help me somebody
Thanks a lot

Koco86 -

It would be real helpful if you showed us the program code that you are using now, so we can help you to correct it.

Koko86 -

Two other things ocurred to me as I was waiting for your response. However, as regards that response, please also mention what the actual problem is - "it not work" doesn't tell us much

I trust you are aware that there are only 2 permissable sets of pin ports that can be used to access I2C devices with the BS2p series of PBASIC Stamps. You may either:

Specify 0 in the first parameter and then use pins 0 and 1 (SDA, SCL)

OR

Specify 8 in the first parameter and then use pins 8 and 9 (SDA, SCL)

and no others. Additionally whichever pair of pins you use, each will need to have a 4.7K pull-up resistor on it (SDA and SCL).
