Good day,

I have some problem here, I took some code from another project, I rewrote some parts. But my camera do not want to work. I just want to read the ID of camera through I2C (or so called SCCB), but I always get 0xFF. I even tried to scan all I2C devices (0x00-0xFF). Here is some code:

I use STM3210C-EVAL board with stm32f107 mcu. I connected camera to PB6 (SCL), PB7(SDA), 2.8V voltage and ground. Maybe I did something wrong, but I cannot find the mistake..
