Recently started to contact stm32, still stand a book wrote a OV7670 on TFT display program, completely according to the book did not appear what problem, the program but I again on this foundation to add their own things stuck in the problem, after

# # code:
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */
It is my own program, but will appear after add stuck problem
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */

Add back not to brush full screen, and then want to show that camera data needs to be set the address

Thank you for your bosses!!!!!!
