Re: I2C display plus other I2C devices, 3.3V #ubitx

Our group, the TSW actually had this working long before CEC used it and the only problem you might run into is the Si5351 can accept no more than a nominal 3.3V signal level on the I2C lines. ?If you connect a device to the I2C bus that has pullups to the 5V supply on the data lines, you risk destroying the 5351. ?Address wise, as long as you stay away from the 5351's I2C address, you can have more than one thing operating on the bus. ?

Subject: Re: [BITX20] I2C display plus other I2C devices, 3.3V #ubitx I have not yet done the mod, however KD8CEC at Hamskey.com has used the I2C line to link in second displays and Nano's for increased functionality.? To me that would imply that you can use the link to the Si5251. |
