Powering WF32 through USB - seems dead

Question

My first time trying out a chipkit.. so I'm a newbie.

 

I have a USB cable from the PC to the USB port on the WF32 and there doesn't seem to be any life at all. 

 

Should I expect at least one LED to light up? No serial port detected either..

Hi bletweaker,

 

Is the jumper on J15 (next to the SD card slot) set to UART? I believe the board normally ships with the jumper block on the EXT (external) setting.

 

Thanks,

JColvin

Thank you! That helped.

 

But now, though I get the LEDs lighting up, I still don't have a COM port showing, so I can't do anything with MPIDE. Is there a driver that's needed?

 

Thanks

Your computer should (in theory) automatically download the FTDI driver that is required to interface the WF32 board with your computer. But before we get into that, lets check a couple of things first before we get too far ahead.

 

What type of computer are you using? Windows, Mac, etc?

 

When the board is first powering up, you should see some strong pulses on LD1/LD2 (as you already mentioned eariler) as well as LD3 being constantly lit up for about 2 seconds while LD6 flashes on and off during that time. Are these LED's lighting up on your board? 

 

Thanks,

JColvin

Thanks for helping. During power up :

 

LED1/2 - no activity

 

steady state : 

 

LED3 : solid, LED6, blinking.

 

I'm running Windows 7 and have no problem with the stock (Atmega) Arduino board (Duemilanove from 2009 )

BTW, the jumper J15 was originally set to UART and I moved it to USB after the first reply here.. The UART seems to refer to the J1 jumper - I don't have a cable with a mating connector for that one. Is that the one we're supposed to use?

Yeah, that jumper is a little weird. The UART connector on JP1 allows power to flow from the USB-mini connector to the board, which is labeled as both UART and J1. The USB option on JP1 allows the board to draw power from the bit Type-A usb connector that flash drives fit into. So you would use whichever jumper setting you plan on powering your board from (the barrel jack or one of the two USB connectors)

 

As for the LEDs, the fact that LED 3 and LED 6 are lighting up shows that your board has the bootloader on it, so we're good in that respect. The LEDs 1 and 2 would be representative of RX and TX which the computer utilizes through the USB port when programming/communicating with the chipKIT. This isn't my field of expertise, but I agree with you that you'll need the correct drive installed. I would first try installing the one that comes with MPIDE. The installation application should be in: "mpide-0023-windows-whatever_version_you_have/drivers/chipKIT_Drivers" with the chipKITDriverInstallerApplication_v10 I believe.

 

Let me know how it goes.

 

Thanks,

JColvin
