Now in use STM32F207 Ov2640 adjustment, timing problems encountered, configuration, according to official svga format output HREF clock is wrong, according to the specifications, HREF effective time of 800 tp, then wait for tp 390, entered the next line, but I debug the clock wait time only less than 1 us will enter into the next line, PCLK is 24 m, for the great god who know how to configure!!!

To be the same in the rear of the sensor, find detailed fae support

CodePudding user response:

Again carefully,

CodePudding user response:

Now is 800 * 600 can enter the DCMI interrupt, but if change resolution of 320 * 240 words will not be able to enter the interrupt, STM32F429 according to modify the program, the basic configuration is consistent, are there any restrictions on it is DCMI STM32F207?

reference 1/f, fog oasis response:

can be used to the same in the rear of the sensor, find detailed fae support

OV2640 still a lot of, the use of use STM32F4 tuning is very much also, but couldn't find her STM32F207 debugging experience, but the theory is the same
