Posted on March 09, 2015 at 17:56I can't understand how come TIM1 frequency is 42 MHz. Here is my config: 12 MHz HSE -> 168 MHz PLLCLK (MCO/4 = 42 MHz, checked) APB1 prescaler = 4 APB2 prescaler = 2 so TIM1, as it clocked from APB2 x 2 frequency sho...
Posted on January 26, 2015 at 14:48 Hi, It's already a few weeks I'm trying to bring up a solution of the USB Host via USB HS module with internal FS PHY. The same code works fine if I use OTG_FS module, once I pass to OTG_HS I'm starting ...
