How to conditionally compile multiple binary executables

How can I configure an ESP-IDF project to conditionally build multiple executable binaries from a common source set?

Regards,
Steve.

Re: UART ISR not located in IRAM

Hi @ESP_Angus

Would it be safe to only place functions in IRAM that are called by enabled interrupts?

For example if the pattern match interrupt is disabled can these functions be excluded safely from IRAM etc?

Thanks,

Re: ESP32 External RTC 32K

We also want to do this, any information regarding its viability would be appreciated.

If it is possible to use an externally generated clock to supply just XTAL_32k_P, can XTAL_32k_N be reused as a GPIO?

Thanks

Re: New tool for "make monitor": idf_monitor

@ESP_Angus, It would be really helpful to be able to disconnect the 'monitor tool' and then re-connect it again later without causing a reset to the board. Is there no way to achieve this? For example, I am running some long term tests to check timing etc. and I want to connect to the board to check...

Re: [Video]: Bleutooth BLE and C++ classes

@Kolban Hi Neil, I have a few questions / suggestions: 1) Given your answer to my question about IDF version, do you not find that you encounter problems as things are changed (potentially daily) in the latest active IDF? Or do you take a snapshot of the latest IDF when you begin to develop a new pr...

Hey Neil, just wondering which version of the IDF your'e testing this code against?

2.0 being the current stable release, but further changes and enhancements are in 2.1r1

Re: [Video]: Bleutooth BLE and C++ classes

Hi Neil, I believe indications and notifications are two slightly different things. Both automatically inform the client/central device of a change to the peripheral/server characteristic but they differ in the acknowledgement: Indication (requiring an acknowledgement from the client/central device)...

Re: [Video]: Bleutooth BLE and C++ classes

Great work Neil. I was thinking that the BLE interface could do to be a bit simpler myself. The use of C++ classes looks like a good way to go. Wonder why Espressif didn't do it like that in the API.
Looks like it'll make building BLE peripherals much easier.
