Support Ultra-Low Power Himax HM0360

[superware]

Hello,

Himax HM0360 is an Ultra-Low Power camera, pretty cheap for such low power consumption and internal motion detection (any supported alternatives?), supporting 8-bit parallel CMOS level interfacing.

It's currently being marketed "for Raspberry Pi Pico", using the 1-bit interface and monochrome variant (HM0360-MWA) so that a single frame (640x480x8bit) will fit in the RBP Pico RAM. ESP32 with PSRAM seems much more suitable to support this camera (including the RGB variant HM0360-AWA), no idea what's the historical reason though.

• How complicated will it be to support it in esp32-camera? Since it doesn't seem to support SCCB (only "pure" I2C") etc.
• I'm trying to interface it with an ESP32-S3 board, currently only managed to communicate via I2C, is there a quick tutorial/sample code that generically (without using the esp32-camera infrastructure, just pins and frequencies definition) grabs frames through DMA/EDMA to PSRAM?

Thank you in advance!
