bufferGetAtIndex( ) Question

2012-04-02 by englsprogeny1

AVR GCC
Atmega8
Using: Procyon AVRlib



In an attempt to look into the UART_Rx buffer
I make the following call:

UART_Buffer[count] = bufferGetAtIndex(uartRxBuffer,1);

I get the following Error:
error: incompatible type for argument 1 of 'bufferGetAtIndex'


-----------------------------------------------------
Looking at buffer.h:

//! get a byte at the specified index in the buffer (kind of like array access)
// note: this does not remove the byte that was read from the buffer
unsigned char bufferGetAtIndex(cBuffer* buffer, unsigned short index);

--------------------------------
from uart.c:
// receive and transmit buffers
cBuffer uartRxBuffer;				///< uart receive 
cBuffer uartTxBuffer;				///< uart transmit 

_____________________________________________________

I don't understand what is wrong with:  uartRxBuffer (as it is type:cBuffer )


Any ideas?


Thanks!

Isn't the first argument a pointer to a type of cbuffer so should be 
 
UART_Buffer[count] = bufferGetAtIndex(&uartRxBuffer,1);

What version of GCC are you using ?
 
Regards

Steven,

You are correct.  I don't know why but I had it in my head that uartRxBuffer was an array....

Thank you!
