Micro sd

Hello,

You provide only 3 different pin for tf card but need mimimum 4 ?

Thanks

1 bit mode, so only 3 IOs are required. Please see the example

[telemac73]

I try to have it workin in micropython and no example

[telemac73]

I have also test with the example and i get same error i test with 4 different sd card:

E (2173) sdmmc_req: sdmmc_host_wait_for_event returned 0x107
E (2173) sdmmc_sd: sdmmc_check_scr: send_scr returned 0x107
E (2174) vfs_fat_sdmmc: sdmmc_card_init failed (0x107).
[ 2275][E][SD_MMC.cpp:138] begin(): Failed to initialize the card (0x107). Make sure SD card lines have pull-up resistors in place.

Thanks i will try )

@telemac73
I am already trying it... I built my own firmware (based on clean micropython 1.21.0 and esp-idf 5.0.2) with changes that @dotnfc suggested in https://github.com/orgs/micropython/discussions/10598 but sd card is still not working... I hope I will figure it out and then I will inform you :)

Guys, you probably have to power on the peripheral from which SD card is powering as well.
PWR_EN (GPIO 10): output, high

@aokhrimenko thank you!!! You are absolute legend and I am totally stupid :D You can see in that other discussion I mentioned above, that I tried everything, I even flashed back original firmware from here and tried Arduino testSD sketch and I am probably totally blind because I completely missed fact that in that code, they trigger gpio10 to 1... I even checked schematic many times and yea I am blind... -_- Ok, so now it works even with micropython - slightly modified micropython - https://github.com/orgs/micropython/discussions/10598#discussioncomment-7545637

This display has good at SD card functionality . TFT_eSPI library also worked fine to draw & Fetch JPG image from SD card . But touch has certain issue to display next scroll. It gives ghost touches continuously of same value and not being integrated with TFT_eSPI library. Please help to resolve touch library
