Nucleo F103RB ADC behaves different from other Nucleo boards using MBED lib
In case of Nucleo F103RB why the first time ADC timeouts as image below and return zero, while 2nd time onwards it catches the EOC flag. Does external trigger for ADC takes time to raise TIM1_CC1 in order to set the EOC and complete the ADC conversion? What is the reason behind this behavior which does not occur with other Nucleo boards?
