Thanks, Sprite! Then we will rename our components to something else.

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...

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...

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...

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

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 ...

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

Could anyone please provide an answer to this topic?
Thank you very much.

Could anyone please confirm this issue?
Thank you very much.
