Hello,
i am trying to read an external Flash over SPI.
On oszilloscope looks data well, but my variable a and b is wrong.
Code:
SPIM_SpiUartWriteTxData(0x03); // Readcomand
dummy = SPIM_SpiUartReadRxData();
SPIM_SpiUartWriteTxData(A_high); // Adress
dummy = SPIM_SpiUartReadRxData();
SPIM_SpiUartWriteTxData(A_mid); // Adress
dummy = SPIM_SpiUartReadRxData();
SPIM_SpiUartWriteTxData(A_low); // Adress
dummy = SPIM_SpiUartReadRxData();
SPIM_SpiUartWriteTxData(0x00); // Dummy
a = SPIM_SpiUartReadRxData();
SPIM_SpiUartWriteTxData(0x00); // Dummy
b = SPIM_SpiUartReadRxData();
I use SS Pin automatic. And a read 16 bit value (2 times dummy 0x00 at mosi pin)
My problem is, a und b is wrong.
Somebody know, was can the problem be? Component "SPIM" has default settings. Master Mode, CPOL 0
Thanks
Best regards
Alex
