TASK$3$

In this task you will display a $3-$bit binary number depending on the analog input voltage value.

LEDs should be $111$ for highest analog voltage $($all three LEDs are on$)$ and $000$ for the lowest

$($all three LEDs are off$).$

Configure ADC to be in single conversion mode. Use TIMER$1$ and

HAL$\_$TIM$\_$PeriodElapsedCallback to perform a single conversion with each timer interrupt.

Timer$1$ update interrupt period must be $20ms.$

Application notes:

Use CubeMX configuration tool and HAL Library for this task

Use Timer$1$ interrupt callback to start a single ADC conversion every $20$ms

Use ADC in single conversion mode and restart conversion inside Timer interrupt

callback.

Component list:

$1$x STM$32$F$401,3$x LEDs, $1$x potentiometer, jumper cables
