I2C Master status

[Anonymous]

Hello

   

I read the return value of SCB_I2CMasterStatus() after executing SCB_I2CMasterReadBuf(). The value is infinitely 0x04, SCB_I2C_MSTAT_XFER_INP. Its mean are "Transfer in progress". It seems that Slave returns Nak.

   

So even if I try to send next transaction by SCB_I2CMasterWriteBuf(), I2C does not work anything.

   

Do you think why this is happned?

       

Thanks.

Can you please post your complete project, so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.

Hello Bob,

   

Thank you for your suggestion.

   

Now, I resolved this issue by waiting a long time before accessing to MBR3 from PSoC4 and by using another API for manual control.

   

Thanks and regards,
