sdCard support, m5stack coreS3

[mhaberler]

Hi Sukesh,

we discussed this over at LovyanGFX - I got this to work with M5Unified/M5GFX but not with LovyanGFX for a m5stack coreS3 target - so here I would have a potential fallback even if I like LovyanGFX

it seems the coreS3 is part of the BSP, but I'm pretty fresh to esp-idf

could you guide us through an example of adding a new target?

I guess this involves tickling the component manager to add the board support

thanks in advance!

Michael

Not sure what the catch is but it says

The SD card is not working simultaneously with the LCD screen. We are working on a fix.

I don't have that device to test it.

It should work if you don't re-initialize the SPI bus (for uSD) if TFT & SD Card are on the same SPI bus.

so was my theory, and I tried that with lovyan but didnt get far
I'll have a look at the BSP approach eventually, currently the cores3 is not the top option and better variants like the LilyGo or Sunton units dont have that issue

It was working fine in my ESP32-TUX project which uses LovyanGFX.
Maybe something specific to CoreS3?

good point
I'll revisit that

Did you try their Arduino sample?

no, because at some point in time M5CoreS3 was way behind what M5GFX/M5Unified offered with less hassle and it seems M5Stack was dropping the M5CoreS3 lib altogether in favor of M5Unified - which made sense

but thanks, yes I should try that
