Re: SDCARD/MMC MODE

Hi!
check
arduino-esp32/libraries/SD/examples/SD_Test/SD_Test.ino
and arduino-esp32/libraries/SD_MMC/examples/SDMMC_Test/SDMMC_Test.ino for pinout
Your pins used in SDMMC, not used in SD mode

Re: ESP32 with Triac

Hi!
Make interrupt to zerocross detect. in this interrupt setup timer interrupt.
In timer interrupt make enough time pulse to triac,
or set the triak on, and next zerocross interrupt switch the triak off

Re: High voltage controller with ESP32 ?

Hi!
use Solid State Relay (SSR)
or use optotriac (MOC30xx) + triak to switch main power

Re: ESP32 SD Library Won't Recognize SD Card After Reinserted

Hi!
In the loop delay 2sec.
Remove/insert card in this 2 sec?
In the loop can't wait to insert card, if no card, after 2sec start start_sd() and mount failed.
I don't try this....
