Fluent frequency modulation

Posted on February 08, 2016 at 09:59 Hello there, I am using STM32F4. I am trying to make an application, where I could be able to modulate the frequency (not pwm) of one channel for example in range of 1k - 20k Hz. The problem i encountered...

Question regarding Bit-Banding

Posted on February 08, 2016 at 09:02Hello. I try to use bit-banding feature in a STM32F303 uC on GPIO registers (exactly to change mode of a pin in MODER register). But as I see, all GPIO registers in that uC are on addresses which starts with 0x48....
