Re: Name conflicts between user and esp-idf components
Thanks, Sprite! Then we will rename our components to something else.

Re: Is it possible to support 9-bit multi drop bus on UART?
Another trick we came up that would allow a 9th data bit using the hardware UART is to reconfigure the parity on each byte. For example, if 9th bit == 1 and (data[0:7] & 1), odd parity is configured, and even parity is configured if !(data[0:7] & 1). A similar logic applies to 9th bit == 0. While be...

Re: Name conflicts between user and esp-idf components
From esp-idf build system documentation : If two or more of these directories contain component sub-directories with the same name, the component in the last place searched is used. This allows, for example, overriding ESP-IDF components with a modified version by copying that component from the ESP...

Name conflicts between user and esp-idf components
As of esp-idf v4.1, the idf_component_register macro is one of the preferred ways to register components into CMakeLists.txt. However, if folder name matches between a user and an esp-idf component (common names e.g.: "log" or "bt"), CMake chooses the first folder it finds and adds it to the include...

Re: Is it possible to support 9-bit multi drop bus on UART?
Hello Tom,
You are completely right, a software-emulated UART would do the trick. I have been looking for implementations on the Internet, but most (if not all) are MCU-specific, so they would still need to be adapted to the ESP32.
Thanks a lot for your help,
Xavi

Is it possible to support 9-bit multi drop bus on UART?
Hello, We are designing a device based on the ESP32 which acts as a bridge between devices using the MDB/ICP protocol. Tipically, a UART configured to support 9 data bits is used for this purpose, since the protocol defines a frame as: Start bit | Bits 0 to 7 | Mode bit | Stop bit Where mode bit is ...

Re: esp-idf use of std=gnu99
Hi Angus,
Thank you very much for your answer and the examples provided. Then I guess std=gnu99 is there for historical reasons, right?
Best regards,
Xavi

parttool.py crashes when retrieving partition info
