- Revision:
- 85:024bf7f99721
Release 85 of the mbed library
Main changes:
- K64F Ethernet fixes
- Updated tests
- Fixes for various mbed targets
- Code cleanup: fixed warnings, more consistent code style
- GCC support for K64F
There is a known issue with the I2C interface on some ST targets. If you
find the I2C interface problematic on your ST board, please log a bug
against this on mbed.org.
