[En-Nut-Discussion] Error in 7segtst.c

[Sinisa Dumanic]

After all I successfully init the SPI. But I still can't run my LED display.
I have Olimex SAM7-EX256 board and I make connections on following way: 

uC          AS1108 
MOSI1     DIN 
SCK1       CLK 
SPI1 CS0  LOAD/CSN 
GND         GND 

Then I make changes in Nut/OS Configurator: 
Uner AT91 SPI Bus Controller I change CS0 Port ID (Second Controller) to
PIOA_ID and CS0 Port Bit (Second Controller) 21. 

I define: 

#define NUT_CONFIG_7SEG_CS 0 
#define NUT_CONFIG_7SEG_SPIBUS spiBus1At91 

Did I need to change anything more ? 

Also can you explain other functions: 

extern int Spi7segCommand(NUTDEVICE * dev, uint8_t addr, CONST void *txbuf,
void *rxbuf, int xlen); 
extern void print_7seg(NUTDEVICE *dev, char* chars); 
extern void dot_7seg(NUTDEVICE *dev, uint8_t dotNumber, uint8_t dotCommand);

Sorry, my fault. Was a leftover from an older version of Nut/OS.

Add and modify the following defines to the 7segtst.c:

#define NUT_CONFIG_7SEG_CS 0
#define NUT_CONFIG_7SEG_SPIBUS spiBus0At91

Modify means that you have to select the right chip-select and the 
correct SPI-bus where you connected the display.

Best regards,
Ulrich
