Im try send data from slave to master with interrupt. (with 2 F28335)

master continuous send data to slave, in main {SpiaRegs.SPIFFTX.bit.TXFIFO=1;}.

slave is including rx interrupt program. and read data. Then in rx interrupt programme, slave send data to master (for example 0x0015). but slave dont send. Could u give me example programs ( master program and slave program) ?

Hi Gokhan,

Did you refer this sample code: C:\ti\controlSUITE\device_support\f2833x\v133\DSP2833x_examples_ccsv4\spi_loopback_interrupts

You can configure for slave and master accordingly.

Regards,

Gautam

Hi Gokhan,
Did you solve the problem?
Remember that the SPICLK pin is used as the input for the serial shift clock, which is supplied from the master one. Slave Data is transmitted to the bus when appropriate clock signals are received from the Master.
