Once the Vitamin C is used up, the solution turns blue, because now the iodine element and starch are present. The advanced timer TIM1 can choose 65536 kinds of frequency division, and the frequency division coefficient is 1-65536. The clock of each timer can be separated by the system clock. Except that TIM4 and TIM6 are 8-bit timers, the other timers are 16-bit counted. Now after a short time as the reactions keep proceeding in this fashion, the Vitamin C gets gradually used up. STM8S timer basic interrupt timing.STM8S timers are divided into three categories. The net result, at least for part of the time is that the solution remains colorless with excess of iodide ions being present.
