I'm starting with programming on these boards I have no experience or arduino
this is the code:
#include "stm32f4xx.h" // Device header int main(){ GPIO_InitTypeDef a; }
The program marks me error where it says: GPIO_InitTypeDef a; error: use of undeclared indentifier 'GPIO_InitTypeDef'
When I compile this: compiling cmsis_rv.c... D:\keil\Demo14\RTE\CMSIS_RTOS_Validation\RV_Config.h(10): error: #5: cannot open source input file "ARMCM3.h": No such file or directory #include "ARMCM3.h" C:\Keil_v5\ARM\PACK\ARM\CMSIS-RTOS_Validation\1.1.0\Source\cmsis_rv.c: 0 warnings, 1 error ".\Objects\Demo14.axf" - 4 Error(s), 1 Warning(s). Target not created. Build Time Elapsed: 00:00:10
I have done it as it is in the tutorials. I've tried copying the Blinky sample routes and neither I hope you can help me
