Software / Re: Splash screen replacement
« on: July 12, 2017, 12:41:43 PM »
I've come to pretty much the same conclusions. Designing a new board is out of scope for this project and 320x240 should be worth a try before rejecting. However 4d system seem to have a 3.5" display with both resistive and capacitive touch at 320x480. Doesn't support SPI slave though so we'll need to switch to serial but that shouldn'tīt be a major problem.
Believe resistive touch is the better choice in this case as its less prone to accidentally trigger while fiddling around with the device.

I've tried both firmware 2.1.0 and 1.1.1 (which I failed to upgrade to 2.1.0, see separate thread). Not quite sure about software package but at least the display with 2.1.0 was installed along with its corresponding package.
It shows up at every start-up. I've set the display to clear in the first part of Arduino setup but the splash is still briefly visible during power up. When performing a hard reset (reset button) while still being powered this happens so fast that I can't see the cleo-splash.

Thanks for the tip Rudolph. I've been looking for something like that but Riverdi has a relatively low resolution (320x240) compared to Cleo (480x320) on the same size of display. 3.5" is pretty much the sweet spot size but I need the higher res.
Any chance you have another suggestion? I relatively new in this and don't really know the market.

Thanks, I do hope there are some solution to it. I'm evaluating the screen for a small volume industrial application and to most part Cleo is a really useful product that saves a lot of development time. However since the device will be turned on and off at every use,  the cleo splash-picture is causing some user questions. Having the firmware version shown briefly is fine the cleo picture looks a bit too toy:ish in this case.

Is it possible to change the smiling-Cleo splash screen or make it become blank until the arduino application takes over?

Software / Firmware update fail
« on: June 26, 2017, 10:50:11 AM »
My first CleO updated without any issues but the second one I tired wasn't succesfull and I hope someone could help me out.

CleO firmware version is 1.1.1 (from splash screen) and I try to install v.2.1.0 with CleO PC tools 0.4.7. I've tried this on two different computers. The first attempt from a w10 computer it failed with a message I unfortunately didn't capture. On retry it said "No DFU capable USB device available" and I can't find it in device manager.
I then moved to another computer with w8. In this case it shows up as an unknown device in device manager and I can convince it to use winusb but when reconnecting its again unknown. When trying to run DFU upgrade after installed as winusb I get the Error log below:

Software / Download problem for software packages
« on: June 12, 2017, 10:43:28 AM »
The download of new software packages is painfully slow on an otherwise very good connection. I had the download fail halfway through after 30min. Was the same problem yesterday.

I also had a hard time trying to get my Cleo to work until I found this thread which pointed in the direction that the reverse board might be faulty. It turns out that D11 is connected to ground. When connecting my Uno to Cleo with patch cables it works fine.
Really didn't expect the passive reverse-io board to be the problem. Is it a faulty batch of Reverse boards (rev 1.1)?
