Hi,Chuma87 wrote: ↑Wed Feb 05, 2020 2:43 pmExtra fact:
I use the GPIO_13 pin (wake up) to receive a frequency sent to me by the CDM324 sensor, then analyze it, and after that, take a photo and save it in the SD, which also uses GPIO_13. All this works.
But when using the DS1302, it does not work, and the 5 pins are connected, including VCC & GND (DS1302) to POUT 3.3 / 5v & GND (ESP32-cam)
hello, i really hope someone could help me with these too. it is difficult for me to find the way to connect esp32 cam with RTC..Chuma87 wrote: ↑Sun Jan 26, 2020 6:41 pmHello partners. I would like to know if an RTC module DS1302 can be connected to esp32cam. GPIO13 already in use, what other pins can I use for CLK, DAT and RST?it doesn't let me use GPIO4 because FLAsh is already using itCode: Select all
DS1302 rtc(GPIO_NUM_2,GPIO_NUM_12,GPIO_NUM_15);
