Hi,
I am reading thru the Esp32-p4_technical_reference_manual_en and it very unclear even for a simple query. For instance, I see some example code used GPIO14 for SDIO function, however in the documentation there is no alternate function for GPIO14! So how in the world it works?

Esp32p4 and MIPI camera sensor
Hi,
I am a little bit confused about the MIPI interface on the ESP32p4 and the camera sensor that supports it. I noticed that a lot of camera sensors like i.e ov5640 come with a dedicated module board that I believe performs so level shifting of the camera signals. My question is why can't I ...

Missing DMA IRQ in dvp_isp_dsi example code
Hi,
I am playing around with ESP32p4 controller + ov2640 driver. The sensor identifies itself correctly by replying 0x2640 to ChipID i2c command. I have programmed the PCLK format and everything else withing the driver code + verified with a scope that pclki, HS, VS and data lines all toggle. The ...
