Other Parts Discussed in Thread: TIGER
Hi,
We saw that you recently updated smbus module in the latest SDK. However, it increases ~700B code size. Since we are very size constraint, we want to know if there is a way to optimize it.
Can we eliminate any unused features by specifying build flag upon local build of SDK?
Also, currently, we only use I2C_SMBUS controller on our project, I don't understand why "smbus target" related code is involved here.
Attachment: Code size diff (only show majority difference, coming from smbus.a)
