Line 24:
Line 24: − DOUT on the temperature sensor should be connected to DOUT on the ADC and pin 96 on the FPGA. This can be accomplished by cutting the existing DOUT trace near the temperature sensor and soldering a wire to DOUT on the ADC. DIN on the ADC can then be connected with a wire to pin 5 on the FPGA, or if possible, simply left connected using the original trace. In this configuration, pin 5 on the FPGA will become the SPI MOSI (master out, slave in) line, and pin 96 on the FPGA will become the SPI MISO (master in, slave out) line. DIN on the temperature sensor is left tied to ground, since it is not needed.+

Pin 5 on the temperature sensor should be connected to pin 18 on the ADC and pin 97 on the FPGA. This can be accomplished by cutting the existing DOUT trace near the temperature sensor and soldering a wire to DOUT on the ADC. In this configuration, pin 5 on the FPGA will become the SPI MOSI (master out, slave in) line, and pin 97 on the FPGA will become the SPI MISO (master in, slave out) line. DIN on the temperature sensor is left tied to ground, since it is not needed.
