How Do I use ST software Libraries to set-up an Interrupt using Button S1, S2 or Reset on Keil Dev Board MCB-STR9 ?
Hello Ciaron Dixon,
If you want to use the ST Libraries (including ST Exeption Handler) and you use Keil startup code from file STR91x.s than you have to check the setting Setup Library Exeption Handlers. Use the Configuration Wizzard to check this setting in file STR91x.s.
