Re: Pins SPI, ESP32 S3

We are using these functions to configure the GPIO:
gpio_reset_pin(GPIO_NUM_26);
gpio_set_direction(GPIO_NUM_26, GPIO_MODE_OUTPUT);
And the, we put the GPIO to '1', but always stays in '0':
gpio_set_level(GPIO_NUM_26, 1);

We tried some other GPIOs and they work fine

Re: Pins SPI, ESP32 S3

Hi, Firstly, thanks for the answer! Anoter question related to this... We have the ESP32-S3FN8, which does not have In-Package PSRAM. We want to use the GPIO26 (SPICS1), which according to the datasheet is used for In-Package PSRAM. As we do not have, it should be that easy to use as a normal GPIO, ...

Pins SPI, ESP32 S3

Hi all, I'm doing a design in a custom PCB including the ESP32-S3FN8, and I have some questions about the usage of certain pins, concretely the 32, 33, 34 and 35. Theorically, according to the datasheet, these pins are used by the flash in package. But can we also use these pins for another thing? A...
