Are you cloning it? Hi Derick, ********************************************** int file; Starting EBB SPI ADC Example I work through the code in some detail and explain how to write the code for the reaction timer. I added a note to the chapter6/ web page on this issue for bone70. Unfortunately I cant get the Qt in the cross-compile environment to install. I do plan to do a pass on the book for 3.14.x now that it has been officially released. minicom is opening but not able to see the data, here i not did any Thanks for that. fine..

The Vref pin in Figure 8.A1 does not have to be set at 3.3V, however it is a useful initial range. If so, how do I enable the SPI0 device?
