Insert the following definition of the delay() function after Error_Handler(). It is not an in-built function therefore we will have to define it as well. In between these two functions, we are calling the delay() function. The case where we are specifying the third parameter as GPIO_PIN_RESET, it sets the onboard LED pin to LOW whereas when we are specifying the third parameter as GPIO_PIN_SET, it sets the onboard LED pin to HIGH. USB) ST-Link GND (even-numbered pins from 4 to 20) to BP Ground. Apart from the STM32 Blue pill board used in this tutorial, there are many other popular STM32 boards like the STM32 Nucleo Development board. That means the current required to drive coils by applying a sequence of control signals is also almost 200mA. To use a ST-Link to programme a blue/black pill (BP) under external power, connect it like this: BP under external power (e.g. This is necessary because the current consumption of 28BYJ-48 is around 240mA. Remember to replace ‘LABEL’ with your own pin label. To use a 28BYJ-28 stepper motor with the STM32 Blue Pill, we will be required to attach it with the ULN2003 motor driver. Notice that we had labelled the onboard LED as ‘LED’ hence we have specified LABEL_GPIO_Port and LABEL_Pin : the first two parameters as LED_GPIO_Port and LED_Port. This function will be responsible for setting the onboard LED pin either HIGH or LOW. Now what is happening is that the HAL_GPIO_WritePin() function takes in three parameters: the onboard LED port, the onboard LED pin, and the state of the pin. HAL_GPIO_WritePin(LED_GPIO_Port, LED_Pin, GPIO_PIN_SET)
