Hello,
I'm working on a project which need that the HPC connector I/Os are supplied by Vadj = 3,3V.
So I use an I2C IP to program the UCD9248 component. (impossible to use the GUI software)
I've developped a code which send to this component the following frames :
(slave adress + write bit), page command, 0x0003 => to select the rail 4
(slave adress + write bit), Vout command, 0x3400 => to configure approximatively 3,3V
then i put vadj_on_b down to supply.
I've removed the jumper J65 before power on the card.
With an oscilloscope, i can see all those frames running on the I2C bus.
But When i probe the vadj voltage, i measure 2,5V.
Could someone help me programming this?
