5.55 CMD_LOGO - play FTDI logo animation
The logo command causes the co-processor engine to play back a short animation of the
FTDI logo. During logo playback the MCU should not access any FT800 resources. After
2.5 seconds have elapsed, the co-processor engine writes zero to REG_CMD_READ and
REG_CMD_WRITE, and starts waiting for commands. After this command is complete,
the MCU shall write the next command to the starting address of RAM_CMD.
C prototype
void cmd_logo( );
Command layout
Examples
To play back the logo animation:
cmd_logo();
delay(3000); // Optional to wait
While( (0 != rd16(REG_CMD_WRITE)) &&
(rd16(REG_CMD_WRITE) != rd16(REG_CMD_READ) ));//Wait till both
read & write pointer register are equal to zero
