hello everybody !
I have used a code source example for UART in order to comunicate with terminal (cutecom) on linux.
I arrive to send and receive data with cutecom ( I use a FTDI for USB --> UART that i have plugged on LPC11U14).
My program work.
Now, I want to send the data that i recovers in UARTbuffer to SPIbuffer?
So in my project files, I have imported SSP.C and SSP.h (I found on website)
This SSP.c file allows to do a Loopback test, write/read on SEEROM or communicate with Master and slave.
I ask me how we can send directly data...
So my first idea is to create a global variable( a table) and copy the UARTbuffer to SPIbuffer.
How i could do it ? I write an example on the fly
int main ()
{ int8_t toto;
uint8_t* ptoto=&toto;
SystemInit();
UARTInit(9600);
SSP_IOConfig( SSP_NUM ); // allows to configure IO SSP
SSP_Init( SSP_NUM ); // allows to initialize SSP
while(1)
{
if(UartFlag==UART_Flag_DataReady) // allows to know if there are data
{
toto = UARTBuffer[0];
toto = SPIBuffer[0];
toto +=8;
UARTSend(ptoto,1);
SSP_Send( 0,ptoto,1);
UartFlag=UART_Flag_WaitRx; //ok for next octet
}
}
return 0 ;
}
Thank for your answers
