hello every one , i need conversion of a digital data ( BPSK signal) on 8bits to analog signal to visualise on osilloscope , so i connect the I/O of FPGA to a home made R2R DAC , but i have a sine wave on my osilloscope without phases inversion , what is wrong ?? , i want to purchase a R2R pmod of digilent , is it suficient to obtain my signal or i must add some progammation on vhdl ( SPI or I2c...) ??
