STM32 Development Log: Timer settings

Always backup main.c before generating code. 

 HCLK = 200 MHz

1. D2PPRE1 = /2, again multiplied by 2 for APB1 Timer Clock , APB1 Timer Clock alone is back to 200
2. APB1 Peripheral Clock = 100 MHz, APB1 Peripheral Clock is not multiplied by 2, it is 100 only
3. APB1 Timer Clock = 200 MHz
4. Prescaler = 199, Counter Clock = 1 MHz, Auto Reload (Period) = 199
5. 200e6/200 prescaler = 1e6, 1e6/200 prescaler = 5000 Hz
6. control loop Period = 200 µs, update Frequency = 5000 Hz
