Re: C++ programming with ESP32 Lyrat

Note that C and C++ are mostly interoperable, and ESP-IDF (the SDK ESP-ADF is built on top of) supports the base C++ language as well. You should be able to write additions for ADF in C++ if you so desire, even if we don't have explicit examples of it.

Re: Timeouts for a specific task | Error correction | Architectural advice

That's very hard to answer without looking at the code, I think.

Re: Can't get unit test to work with IDF 4.0

You need an extra helper tool called 'xxd', which is used to convert the jpeg image into something that can be embedded in the binary.

Re: SPI Master Slave handshake with spi_device_queue_trans

You cannot use the same t_send; by queuing the transfer, you effectively hand over ownership of that memory to the SPI subsystem (and as such, you shouldn't in any way) until it gets returned to you using get_trans_result.

Re: Timed out waiting for packet header

This is a really generic error that just says 'can't communicate with the ESP32' and can be caused by lots of things: from the ESP32 not getting into boot mode to you having selected the correct com port. Can you try connecting to the serial port that the NodeMCU provides directly and see if you get...

Re: Share embedded certificates between projects

You could make common_files into a component (by dropping a component.mk into the dir), then use EXTRA_COMPONENT_DIRS in the project makefile to refer to that path.

Re: which external flash can i use for replacing internal flash

Let me stop you here:
I want to use micro sd card as main memory
If you mean 'instead of the internal SPI flash', that's not possible, period.

Re: Executing instruction from ram gives "InstrFetchProhibited"

The Xtensa has pretty rigidly separated instruction and data buses; the 0x3Fxxxxxx range is strictly data-only, while the 0x40xxxxxx range can only execute instructions (and allows 32-bit aligned loads/stores to get those instructions there). I'm not sure what you use to get the memory range, but yo...

Re: failing to use external RAM

I don't recall if that's the case, sorry. Should be easy to check.
