    Groverkaw reacted to Toby in Understanding SPI read from slave   
    Hi Folks
     
    Ive recently started looking at using the F2802x SPI. For my application I would like to be able to communicate between two F2802x devices a string of 8-bit chars of arbitrary length (+using FIFOs), and I have a few questions.
     
    The slave device is able to request read service from the master by means of a GPIO line to the master that the master has configured as an external interrupt.
     
    The thing is I am not understanding the steps required for the master to begin a read from the slave.... I checked out the data transfer example (sect 1.5.5) in the SPI ref guide (SPRUG71B) but TBH I didn't really understand what it was trying to convey...
     
    I guess the master needs to transmit dummy bytes for every byte that it wants to receive, is that right?
    But how should the master "know" how many bytes that should be? Maybe it just keeps going until the slave clears the TALK bit?
     
    Thanks

    Hi !
     
    At first sorry for my bad english ...
     
    I am beginner and  a new user of Texas MCU/DSP . My first question
    is very simple. In the several examples we can see very intersting codes,
    but I would like to know where can I  find the reference doc where I can
    find the list of all commands and syntax. For example :
     
     GPIO_setMode(myGpio, GPIO_Number_0, GPIO_0_Mode_GeneralPurpose);  GPIO_setDirection(myGpio, GPIO_Number_0, GPIO_Direction_Output);   But now if I want to read the value on the PORT_0 I assume it is ---> Direction_Input ? Where can I find this information ? For ADC, TIMER and so on too.... ??   Thank you for your support. Sorry for my stupid question....   Best regards, Oblivion
