ok, but this is a very uart example.......i am sending a single character. I can use the keil debug

OK, but i haven't oscilloscope or logic analyzer....

Hi, thanks for your answer. I didn't use the OR, but there is the weird character. I didn't understand this:GPIOA_AFRH=(GPIOA_AFRH & ~0xFF0) | 0x770; // PA9/PA10 AF7I used int for registers but nothing...WIthout the adapter the circuit cannot works.....

the weird character is this: ÿ. I use a baud rate of 115200.

Hi eveyone, i am using stm32f207zg and i want to do a multi channel conversion with adc1. The input pin are PA5 e PA6. The problem is when i play the program: in particulare using debug i note that adc doesn't conversion as the sequence is defined.

Hello everyone, I am using stm32f207zg with usb ttl converter with ftdi chip. I want use the usart1 for communication with PA9 e PA10 pins as TX and RX of usart1. I use as virtual terminal, termite, and when i play the program, appear weird characters.
