If CPOL is set, the SCK pin has a high-level idle state. Note: There is no particular order in which these pins are arranged. ), so there is a limitation that we can only use an interrupt for ‘Pin #X’ on one of Connect the serial cable to the UEXT lines of the UART interface (pin #3=TX and pin #4=RX). Now you might be wondering why we are not using the micro-USB port to program the board just like any other Arduino boards. That example was based on polling method where the code continuously monitored the logic state of a GPIO input pin attached to a push button to determine the delay amount. STM32 Primer - A minimal example. The counter of IWDG is start from 0xFFF and reset the MCU when the counter reach 0x000. STM32 is a diverse family of 32-bit microcontroller used in a wide variety of applications today, ranging from simple toys to even complex control systems like home appliances. Main point: For pin IO configuration, use GPIO_Init() in the library or function GPIO_Init_Mode() (simpler to use) introduced here. It is just the reset; used to reset the uc once new code has been uploaded. instead of GPIOA0, GPIOB12, etc. Now there is a new tutorial that explain how to use TIMER in PWM mode with spreadsheet for calculate the values of PRESCALER, PERIOD and PULSE that is here.
