Hi~ this is Morgan Park from one of your Korea Disty.
I got an issue on Updating the Gauge Configuration Parameters.
One of our customer tried to change configuration but it's pending now.
We found something to be casue this issue as below.
1. SubclassID in Quick start guide and Technical reference doc are different
- Quick start guide page4. figure1 : OLD_DC[2] = I2CReadBlock(0x4A, 2, 100)
- Technical reference page12. section3.1, step8 : rd 0x43 OLD_DesCap_MSB; rd 0x44 OLD_DesCap_LSB;
2. New Checksums are different
- Technical reference page12. section3, step 11 : left side(0x1F), right side(0x58)
Actually both I and our customer are checked(computing) 0x58 is right as below.
-----------------------------------------------------
OLD_Csum = 0x8A
OLD_DesCap_MSB = 0x04
OLD_DesCap_LSB = 0xB0
temp = mod(255 - 0x8A - 0x04 - 0xB0, 256) = 0xF3
NEW_Csum = 255 - mod(243 + 0x04 + 0xB0, 256) = 0x58
NEW_Csum = 0x58
-----------------------------------------------------
And then customer applied another parameter value they're ganna use in same way. But it didn't work too.
And now soft_reset(step12) does't work.
Please explain why SubclassIDs are different and what "0x1F" means.
There's no additional docs in website and TIK now.
I hope your detail answers soon.
Thanks.
