Hi everybody !
I'm currently working on a project with a ADuC847 and I would like to copy the content of SBUF (data register of UART) to SPIDAT (data register of SPI). Here is a part of my code:
T3CON = 0x83; //9600 Baud rate
T3FD = 0x12;
SCON = 0x52; // UART enable, variable baud rate.
SPICON = 0x2C; // SPI enable, slave mode
while(!RI); //interrupt flag of UART (Set when SBUF is full)
if(ISPI==0 && RI==1)
{ SPIDAT = SBUF; // This line doesn't work. Value is still egual to 0
value = SPIDAT; }
RI = 0; ISPI = 0;
Someone would have any idea ? thanks in advance,
Guillaume.
I'm not telling that the processor has a serious design issue ! But I have to send data which come from the UART and send them via the SPI. I just want to create a "link" between UART and SPI. I guess that I have to do this with the two data registers SBUF and SPIDAT. I'm right? I absolutely do not question the processor.
For information, the hardware work well, it's an Analog Devices kit (EVAL-ADF70xxMBZ2). The problem is certainly my code!
