In the example from Keil I have this setting for SPI

/* Configure SPI1 pins: SCK, MISO and MOSI */

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7;

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;

and

SPI_InitStructure.SPI_Direction = SPI_Direction_2Lines_FullDuplex;

SPI_InitStructure.SPI_Mode = SPI_Mode_Master;

for MISO the GPIO is output Alternate function push-pull,but the MISO is Master input Slave output,and for Master mode MISO is input,is OK to use this setting?,and why MISO is output?

Hi there my name is Gavin and I live in scotland. I am trying to write an assembly program for a random dice. I was wondering if you woud know how to initialize the ports and use the timer with the thumb assembly? I have been scouring the net and can't seem to find what I'm lookin for. Many thanks for any help, Gav
