Other Parts Discussed in Thread: UCD90160
Tool/software:
I currently using UCD90160A IC in my design. And I encounter issues as below:
a. When I run the i2cprobe command in a high-temperature environment (45°C), sometimes it fails to detect the UCD's addresses (0x0C, 0x41, 0x7F). Please advise. Thank you!
root@(none):/# i2cprobe 1
Valid chip addresses: 0c 21 22 41 70 71 7f
root@(none):/# i2cprobe 1
Valid chip addresses: 0c 21 22
root@(none):/# i2cprobe 1
Valid chip addresses: 0c 21 22 41 70 71 7f
b. When I try to read the 'Manufacturing Info', some information is occasionally lost.
