[PIC] Code reusablity for two DHT11 sensors in PIC1f877a

[7ezhil7]

I am doing a project in PIC16f877a with 2 DHT11 sensors.The sensors where placed at different places.But the code for both of the sensors were same.I would like to reuse the code.I dont know how to do that...

#define dht11pin locpin;
#define dht11dir locdir;
........
........
void main()
{
locpin=PORTAbits.RA0;
locdir =TRISAbits.TRISCA0;
}

I tried above code but i shoots an error as 'undefined locpin'.
Please suggest me a way to reuse my code.

Who knows, what library did you used and how it works...?

 

[7ezhil7]

I haven't used any library..i have programed using dht11 datasheet.

Basicaly, that means, that we don't have any chance to help you...

Is there any way to reuse code in PIC?
By any choice can I pass a pin as argument to another function?

 

[Easyrider83]

pin as argument is a most popular and basic way. Sure, it is a best choice for your purpose.

Just an example:

typedef struct
{
  unsigned char I2C_Address;
  unsigned char (* I2C_SeqRead) (I2C_SW_InitStructTypeDef * I2C_Struct);
  unsigned char (* I2C_SeqWrite)(I2C_SW_InitStructTypeDef * I2C_Struct);
  I2C_SW_InitStructTypeDef * I2C_SW_InitStruct;
}BME280_InitStructTypeDef;

I2c driver for BMP280 sensor. Works with s/w and h/w i2c.
