Posted on June 21, 2018 at 16:38I got this STM32 NUCLEO-F767ZI. The USB port (CN1) on it got broken.I know I can power the board from Vin, but is there a way I could upload the code / communicate with board without using CN1 (USB port).Thanks#stm32...
Posted on June 21, 2018 at 16:19Hello there,Our new device use STM32F413ZG MCU, and use STM32CubeMx to generate Keil uvision5 project. The device USB as serial port to transmit data.In the STM32CubeMX, I chose USB_device is Communication Device Cla...
Posted on June 15, 2018 at 10:00Hello, I am using TIM2 peripheral and many times f(DTS) is mentioned , what is that ?also what is the purpose of clock division settings ?does it divide the internal clock ? (CLK_INT)#stm32f4 #timer
