     85
     86To interact with the data for the hex displays in raw mode, the following functions must be used:
     87{{{
     88WarpV4_UserIO_WriteRaw_[LeftHex|MiddleHex|RightHex](baseaddress, value)
     89WarpV4_UserIO_ReadRaw_[LeftHex|MiddleHex|RightHex](baseaddress)
     90}}}
     91
     92The ''value'' for the WriteRaw function must be 8 bits wide and arranged as follows [A B C D E F G DP]. The ReadRaw function returns a 8-bit number in the same order.
     93
     94'''I2C LEDs:'''
     95
     96The 8 LEDs that are not directly connected to the FPGA but controlled through an IO Expander can be written to using the following function call:
     97
     98{{{
     99WarpV4_UserIO_Write_ExtraLeds(baseaddress, value)
     100}}}
     101
     102where ''value'' is 8-bits wide with each bit corresponding to each LED to be written.
