after moving a whole project from C to a c++ project, had trouble with the lcd librarry.
On the C project, the library works fine. But in C++ i get the following error
Error[Pe513]: a value of type ''int'' cannot be assigned to an entity of type ''TLCD_NAME_t''
Error[Pe511]: this operation on an enumerated type requires an applicable user-defined operator function
This is the initial declaration of TLCD_NAME
typedef enum
{
TLCD_RS = 0, // RS-Pin
TLCD_E = 1, // E-Pin
TLCD_D4 = 2, // DB4-Pin
TLCD_D5 = 3, // DB5-Pin
TLCD_D6 = 4, // DB6-Pin
TLCD_D7 = 5 // DB7-Pin
}TLCD_NAME_t;
This is the code
where it points the error
GPIO_InitTypeDef GPIO_InitStructure;
TLCD_NAME_t lcd_pin;
for(lcd_pin=0;lcd_pin<TLCD_ANZ;lcd_pin++) {
// Clock Enable
RCC_AHB1PeriphClockCmd(LCD_2X16[lcd_pin].TLCD_CLK, ENABLE);
GPIO_InitStructure.GPIO_Pin = LCD_2X16[lcd_pin].TLCD_PIN;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;
GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
Ok, from what i mannaged to understand is that it wont let me assign numbers to its structure positions, why? How can i increment each position of it?
