STM32 OLED Display and Measurement Initialization - Code Breakdown

The code snippet initializes and configures the OLED display, sets the voltage and current values, and starts the timers and encoders for measurement. \n\nHere's a breakdown of the code:\n\n1. `OLED_Init();` - Initializes the OLED display.\n2. `OLED_Clear();` - Clears the OLED display.\n3. `extern float SET_V,SET_I;` - Declares two float variables for setting voltage and current.\n4. `__HAL_TIM_SET_COUNTER(&htim3,((uint16_t)(65535-SET_I200)));` - Sets the counter value for Timer 3 based on the current value.\n5. `__HAL_TIM_SET_COUNTER(&htim4,((uint16_t)(SET_V20)));` - Sets the counter value for Timer 4 based on the voltage value.\n6. `HAL_TIM_Base_Start_IT(&htim1);` - Starts the high-level timer with interrupt for timing purposes.\n7. `HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1);` - Starts the PWM output on Timer 1, Channel 1.\n8. `HAL_TIMEx_PWMN_Start(&htim1, TIM_CHANNEL_1);` - Starts the complementary PWM output on Timer 1, Channel 1.\n9. `HAL_TIM_Encoder_Start(&htim3,TIM_CHANNEL_ALL);` - Starts the encoder input on Timer 3 for current measurement.\n10. `HAL_TIM_Encoder_Start(&htim4,TIM_CHANNEL_ALL);` - Starts the encoder input on Timer 4 for voltage measurement.
