Web21 Mar 2024 · Quick recap and some SEO terms for anyone googling this: if the INPUT_PULLUP or INPUT_PULLDOWN aren't working on ADC pins like GPIO25 or GPIO32, … WebSD pull-up requirements apply to cases where ESP32 uses the SPI or SDMMC controller to communicate with SD cards. When an SD card is operating in SPI mode or 1-bit SD mode, the CMD and DATA (DAT0 - DAT3) lines of the SD bus must be pulled up by 10 kOhm resistors. SD cards and SDIO devices should also have pull-ups on all above-mentioned …

Web9 Mar 2024 · If you enable its internal 20k pull-up resistor, it will hang at around 1.7V instead of the expected 5V because the onboard LED and series resistor pull the voltage level down, meaning it always returns LOW. If you must use pin 13 as a digital input, set its pinMode () to INPUT and use an external pull down resistor. Web17 Sep 2024 · If your async onRefresh function completes very quickly, you may want to add an await Future.delayed (Duration (seconds: 2)); after it, just so the UX is more pleasant.
