Hi Daniel,
Yes that's the exact same problem I got with my ReversIo - shorted D11 to ground.

Not at all what you would expect from a module comprising a PCB and some headers - as a bonus I got a deaf Cleo as well - both were replaced after we'd tried to remote diagnose (the slow way with questions and answers on here!).

A very Merry Christmas to everyone :)

I think you will find that, simply, SPI is on different pins between the UNO and the MEGA.

See this reference on the Arduino site ...

The only way you can standardise the SPI connections between UNO and MEGA is to use the 6-pin ICSP connector and CleO doesn't use this plug - so no easy fix  :(

The SD contents are included in the updated ZIP file for CleO at version 1.0.1 on the resource area of this very site

Fred, I'll second that request for info on EVE please.

You did check the CleO itself didn't you? - there was a micro-SD pre-inserted into my CleOs.

Of course, now, it may be the initial version and may need to be updated with the latest CleO download.

Well I tried the new package including the new PCTool on my Windows 7 64-bit desktop machine and tried to see if it might fix my duff Cleo.

Plugged Cleo in, got a new USB device "working properly", fired up PCTool, located the update firmware button, clicked it and Bam screen blacked out and the PC rebooted itself.

I daren't try it again with my working Cleos in case it kills them.  :(

I don't suppose there is an Apple (iMac) version is there (Mavericks)?

Hi Fred,
I picked up a parcel from the post office today containing the replacement Cle035, a Reverse-IO and stylus.

Checked the Cle035 - and it worked perfectly out of the box (as did the stylus of course  :) )

But ... you're not going to believe this ... the Reverse-IO didn't work. Tried it with a NerO and a regular UNO - definitely not working. It's a simple board just PCB and pins but the Cle0 refuses to work with it - back to Cleo smiling at me.  :(

I'm going to have to check the connections and see if there is a dry joint or something there   :o

Update: I tried running CleO and NerO (back to back) but with the suspect Reverse-IO fitted topside - ie not in use and the sketch wouldn't start - only smiling Cleo. Not buzzed the Reverse-IO out yet but it looking more like a short somewhere rather than a break?

Update2: My new Reverse-IO PCB has a dead-short between adjacent pins D13 and GND. Can't see anything obvious but it is a solid short-circuit.

Lucky aren't I?  :'(

The only problem I have with Mikroe modules is the documentation (or lack of) usually all you get is example (assembler) code or for some esoteric (to me) processor.

The only limited C I have learned is "Arduino flavoured" so trying to rework the Mikroe supplied examples sometimes doesn't work right.

One other point with a lot of the newer modules is that they are 3.3v - they might come with a voltage change link (a tiny zero-ohm SMD resistor) but the logic is 3.3v based so might get upset with the Arduinos 5v logic and the Mikroe Arduino shield does not include any level shifters (well at least my shield doesn't) gotta be careful with the data port volts there.

That might be a idea for NerO mkII - system voltage switch to run the whole Arduino on 5v or 3.3v to keep peripheral chips/modules happy.

Yup not in USA but 'tother side of the pond  :)

I get Chinese modules from Ebay but they take a month to get here  :(

I have some Mikro modules and development boards they are good quality but quite pricey (certainly compared to Chinese modules) and their "click" modules all come with a standardised pinout.
Mikro also have an Arduino shield with two Click sockets on it - would be a good fit for CleO.

Cleo underneath a Uno or NerO (with long pins) and a Mikro Arduino shield on top gives you two Click sockets to play with.

Had a good rummage and found about using the PCTools.
I've installed it properly but it comes up with a windows error "dfu-util.exe has stopped" then PCTools reports upgrade failed.
I am using Windows 7 64-bit home premium SP1
Tried running PCTools as admin - no difference still failed
Tried running in [XP] compability mode - success dfu-util works but fail cleo upgrade failed again
Dfu-util reports "no such file or directory could not open file cleo_firmware.bin.~~tmp for reading"

In the c:\users\public\documents\cleo pc tools\ folder is a "CLeO_Factory_Firmware.bin" (258,048 bytes)

I'm stuck

Prashanth has suggested I *might* have old firmware in module #84 and that I should try updating the firmware - I shall try that this evening.

Does the screen report version (besides 1.0.0) in the numbers presented on screen at switch-on?
(I never got round to actually seeing if the numbers were the same on both CleOs - will check that too)

Odd the way the duff CleO had IRQ on D2 out of the packet and the good one was on D3.

Well I edited the scribble sketch, adding a delay after the first Show keyword ... and the darned thing worked again.
removed the delay and it still worked.

Really weird. At least I've got my sketchpad back  :)

starting with a working scribble pad application on the good CleO
plugging the duff CleO into my NerO gets me just a smiling Cleo.

Changed Cleo.h entry IRQ to 2, shift the jumper on good & bad CleO to #2 - recompile and upload - good works, bad still doesn't
Changed Cleo.h IRQ back to 3 reset both jumpers to #3
Changed Cleo.h Chip Select to 7, shift the jumper to #7 on both CleOs - recompile and upload - good works, bad still doesn't
Changed Cleo.h Chip Select back to 10, reset both jumpers back to #10
Same again, recompile & upload - however somewhere down the line my scribble application won't work on either Cleo

tried reloading scribble.ino, replacing from downloaded Zip -still broken no idea why

Tried speedometer and nixie both compile and upload and work on the good Cleo and just the darned smiling cleo on the bad one.

Prashanth sent me a "debug" sketch...

Code: [Select]
#include <SPI.h>
#include <CleO.h>
void setup()
  /* Initialize CleO - needs to be done only once */
  Serial.println("Before cleo begin");
  Serial.println("After cleo begin");
  /* Start building a screen frame */
  Serial.println("Before cleo start");
  Serial.println("after cleo begin");
  /* Draw a string "Hello World" at (160, 240) */
  CleO.String(160, 240, "Hello world");
  /* Display completed screen frame */
void loop() {}

Good CleO outputs this...

Before cleo begin

After cleo begin
Before cleo start
after cleo begin

I get a small white font "Hello world" in the middle of a portrait black screen.

But with the bad CleO I get this...

Before cleo begin




... repeating forever

Don't know what happened to my scribble sketch I can't make it work any more and that was a really nice demo.  :(

Hi Fred,

I'm at work at the moment (Air Traffic Control no less  :) ) but will have another crack at NerO and CleO when I get home - circa 5:30 and report my findings.

Given that I have now found out about the IRQ setting line in the code I *might* be able to change the code to use the other IRQ to see if I have an IRQ 10 break. Not the "right fix" perhaps but possibly worth a shot.

Its annoying that the display itself is clearly working but you can eventually get enough of smiling Cleopatra  ;)
