Hi Ben, just to let you know - it seems as if the ECIO keeps unplugging itself from USB after I program it. The device keeps coming and going from device manager. I've unticked the option within power management for the ECIO, but still it keeps doing this for about a minute. The drivers have been in...

Hi Ben, OK - when I used PPP, it seemed to start the code at 0800 and not 0400 as was for you. That is strange! Anyway, I noticed that the configuration bits I had set on MPLAB kept changing each time I built it - which is very strange. So I ended up setting fuses in the code itself but for some rea...

Hi Ben,

thanks for looking into this.

I tried to call the header afterwards as you suggested, but MPLAB then gives an error asking for the header file.

I am attaching the hex file for you to have a look at.

Thanks again for your help.

Hi Ben, thanks for the reply.

Unfortunately, I cannot just keep org as it gives an error.

I tried it without all the top bit and still getting nothing from it.

yes - I do believe the compiler sets the tris registers according to each command selected.

Hi Guys, I am trying to use CCS compiler to work with ECIO40. I am using the MPLAB IDE. Currently all I am trying to do is light up an LED. However, once the PIC is programmed, the onboard LED keeps blinking as if it is in reset - and does not light up the LED I am expecting. My code is as follows; ...

Hi Ben,

thanks for your help. It worked without any problems

Hi,

I've got an ECIO 40 board which I am currently using. I've got windows 7 64 bit on my computer - and the drivers on the website are not compatible. Is it possible for someone to send me the 64bit drivers please.

Thanks.

Thanks for your help.

Seems to be working off the external power now.

Hi Ben, I've tried resetting the the device while plugged to the external power supply - but still nothing happens. While in external power, if I connect the USB cable, the onboard LED lights up, but I cannot program the chip. I've tried to reset it while connected, but nothing happens (LED doesn't ...

Hi, Thank you for your reply. I have the Jumper setting to External, and powered the ECIO board via a DC 5V supply. I have an internal clock generated via the PWM and sent to pin C2. I've looked at that pin using an oscilloscope, but the value of the pin is 0 and will not give a clock output. All ot...

Hi Guys, I've got an ECIO40 development board with the PIC 18F4455 chip onboard. I want to connect it to an external 5V power supply. I've set the jumper to EXT, connected 5V to VDD_IN and both VSS to ground and nothing happens. The onboard LED doesn't come on like it does when powering from USB, an...
