Hi,

by “Led display” you refer to LabBoard display? Nothing on the LabBoard lights up and work? Is flat cable firmly attached to TotemDuino?

If yes - could you measure between GND and +3.3V and +5V pins using multimeter to check if power comes in?

So green blinking LED means that TotemDuino is working fine. Reset won’t help here.
There is a problem with LabBoard not getting power or something is damaged.

Also try a few more tests to indicate the problem:

  • Toggle 3.3V and 5V switch on TotemDuino. Is green LED blinking and red LED is on in both switch positions?
  • Hold SET- button and plugin in power cable to TotemDuino. Does 0.5 LED light up?

I have all the power on +5V, -5V,VREG (2.07 V) , Vin (15V) but nothing on the 3.3 V

There is also 5V on pins 26,27 and 28 of HT 16K33

Ok, so the problem is clear now. One last check is required - disconnect flat cable from TotemDuino and measure 3V3 pin voltage. This is required to indicate if TotemDuino 3.3 voltage converter is bad or there is a short in LabBoard.

When flat cable disconnected from TotemDuino there no power ( 0V) on lab board pin +3.3V

10

Did you mean TotemDuino 3V3 pin? There will be no power on LabBoard if flat cable is disconnected. Measurement should be done on TotemDuino itself.

Sorry I measure 3.3V on the totem Duino board
