feature/openssl: fixup the file and code style
2016-11-15 22:11:01 -05:00
examples: Standardise naming of files, symbols, etc. in examples * Use "example" in all example function & variable names, ie use i2c_example_xxx instead of i2c_xxx for example functions. Closes #198 https://github.com/espressif/esp-idf/issues/198 * Mark example functions, etc. static * Replace uses of "test" & "demo" with "example" * Split the UART example into two * Rename "main" example files to end with "_main.c" for disambiguation
