Other Parts Discussed in Thread: DS90UH949-Q1,
Dear TI Exprts
Our customer is using serializer DS90UH949-Q1 and deserializer is DS90UH948-Q1 and a touch panel over I2C of the deserializer(DS90UH948-Q1).
Now they met with a problem need your help: Touch Panel cannot be used normally
At most of the time, touch panel can work normally, but sometimes it cannot be used,rebooting the system will return to normal.
When the touch panel cannot be used, the I2C CLK of 949 is pulled to 0V; the I2C CLK and data of 948 are normal(High)
Can you give me any advices? Thank you very much~
