tx buffer to pin

[Morten]

Hi I have an ADC that just recive, but i will need to make an buffer that makes tx values and just send them to a output pin.

So I wonder how i should code this and if it possible?

Hi.I am using the nrf51822 PCA10001 as master to the spi, and mcp3201 ADC to recive, but my code need me to make a fake Tx buffer and send them out on a GPIO pin. So i have both transmit and recive. So i wonder how i should do this?

Sorry for bad explanation.

My scenario is that i have build a adapter card with i2c and spi. The spi's function is just to read +in and convert them to digital output. I have now got my CLK and CS to work. The problem is that i dont know how to make an interupt handler to stop the clk signal when the data is recived. MCP3201 is miso only thats why i thought that i needed a fake buffer. another problem that i have is that i dont get any miso data back even when i test the spi master example that is with the nrf51822.

so i just wonder if you maybe have som tip and tricks. From Morten, (Hope this make things better to understand).
