Hello All,
I'm tasked with talking to a device with the 5529 Launchpad. The device address does not matter here. I'm using a protocol analyzer to see what's coming out of the pins and all I get is the address. I'm using the potentiometer wire example in Energia 11. Pull ups are enabled in the debugging tool. I'm using 3.0 and 3.1 as SDA/SCL.
- model of LaunchPad used and revision number
- 5529 LP. Rev 1.4
- model of the MCU used
- 5529
- model of BoosterPack used or model of the sensor or actuator or screen
- I2C with address 0x2C
- name and version of the IDE used
- Energia 11, latest
- OS the IDE is running on
- Windows 7, 64 bit
- whenever possible, minimal code to replicate the issue
- Example code under Energia->Examples>Wire
I'm doing something wrong as I don't see others with the issue.
