Other Parts Discussed in Thread: TUSB1064
Hi,
I am planning to drive the I2C interface of TUSB1064RNQEVM development kit.
My current setup is:
- i2c_EN = 1 (jumper connected to VCC)
- SDA = 1 (jumper connected to 1K and VCC)
- SCL = 1 (jumper connected to 1K and VCC)
(R76 and R78 resistors are not present, as expected)
I did check the voltage for each pin and I have noticed that SCL maximum value is 1.9V (expected 3.3, because the pull up).
Even if I send a single message through the I2C interface, it does not work. For some reason the SCL does not reach 3.3 V at any moment.
Can you help me to understand what is the problem and how can I get info from the device through I2C interface?
