Resolved! Power Supply for STM32F4 Board via USB Vbus
Hi! I am working currently on a stm32 F407, I am implementing USB Communication Device Class with the microcontroller being a device. The microcontroller is powered via the STLink but I wanted to change that and supply it through the usb I am using f...
i2c slave address conflict between B-LCDAD-HDMI1 and B-CAMS-OMV.
When using both B-LCDAD-HDMI1 and B-CAMS-OMV together on STM32M747I-Disc, HDMI has no output. Finally, found that i2c address of OV5640 use the same address of ADV7533 CEC-DSI. Any solution?
