I have built the Explore 100 and am having issues with some commands to configure it. GUI TEST LCD PANEL – DOES NOTHING GUI CALIBRATE –ALSO DOES NOTHING but if I touch the screen it reports “Touch not calibrated” The screen is a 5 inch and the backlight command works OK Do you have any ideas? Regards Jim |

Show us a copy of your options. OPTION LIST also GUI TEST LCDPANEL doesn't have a space between LCD and PANEL Jim VK7JH MMedit |

So, if you issue GUI TEST LCDPANEL and press return, do you get the demo? If not: OPTION LCDPANEL NOCONSOLE - disable the LCDPANEL console for now. Connect via a USB-serial adaptor or the USB port(which version of the E100 do you have?) Issue the same GUI TEST LCDPANEL command via the USB-serial adaptor - does it work now? Perhaps there is some issue with GUI TEST LCDPANEL or touch testing commands, when MMBASIC is configured to use the LCD panel as the console. I would not think so, but it is best to test this idea. I will see if I can rustle up an E100 and a 5" LCD, set them up as you have, and see if I can get the same problems. Oh, and welcome to the forums, BTW.  Smoke makes things work.

Hi, Made no difference i’m afraid. Some commands (SDCARD, RTC) seem to work but anything to do with the screen appears not to. Maybe a faulty screen? PS the backlight command does work! Regards Jim |

Do you happen to have another LCD you can try? Smoke makes things work. When the smoke gets out, it stops! |

No, you would need another 5" parallel interface one. This is odd. As you are using a PWM pin to control the backlight, that mode DOES NOT use the 1963 chip to control the backlight, it is just a pure PWM control signal, and will work on the backlight, regardless of what the 1963 controller is actually doing.

have you tried the alternative driver (without the 'A') OPTION LCDPANEL SSD1963_5, LANDSCAPE, 48 you would have to disable the original one first OPTION LCDPANEL DISABLE VK7JH MMedit |

Thanks, I disabled the lcd and used the option without the “A” same result no GUI test. I have ordered a replacement panel in case Should I move the zero ohm resistor to 1963_PWM and see if the backlight control still works? Regards Jim |

The screen is totally blank and the console,test or calibrate commands do nothing.I can vary the backlight. regards Jim |

Make sure the 10K pulling RD on the LCDPANEL high is in place. Pin 6 is specified after v5.3 to nominate the RD pin so that BLIT etc can work. > option list OPTION AUTORUN ON OPTION LCDPANEL SSD1963_5, LANDSCAPE,, 6 OPTION TOUCH 1, 40 OPTION SDCARD 47 OPTION RTC 67, 66 Latest F4 Latest H7 FotS |

I thought so, the GUI commands are really meaningless 99% of the time unless you actually have some standard text displaying. As the post above said, go back and check connections, soldering and voltage, it could be a display fault but I'd exhaust other hardware tests/faults first. EDIT: I assume you're looking at the backlight LEDS in the PANEL to tell that the backlight can be changed when using the backlight command? NANO Inverter: Full download - Only Hex Ver 8.1Ks |

The Micromite just sends commands to the LCD Panel and does not expect a response (the panel is just a receiver of data, it does not reply). This means that you can change the backlight and not receive an error... even if the panel is faulty or not connected. Geoff Graham - http://geoffg.net |

hi, Using pin 6 for backlight did not work reverted to 48 and the backlight works and responds to the backlight command from 5% to 100% tried the touch option_no response sdcard option 47 did not work as i am using the micro socket on the PCB so used 52 files command read the sd card OK You are correct, I am watching the backlight leds to gauge the panel is on I have given the panel a good inspection for bad solder joints etc, all seems OK Regards Jim |

Who built the M100? I was thinking more along the lines of checking the M100 LCD socket and supply lines. NANO Inverter: Full download - Only Hex Ver 8.1Ks |

pin 6 is for the RD pin, an additional optional parameter after v5.3. There is a sneaky comma in there, the 48 is left out if you are using the PWM backlight. Not adding the pin 6 option will not stop it working provided the 10K pullup is there, just not allow use of BLIT and transparent text which need read mode enabled. this might be useful Latest F4 Latest H7 FotS |

Jim, Do you have access to an oscilloscope? If so, at the console, start the LCD test with GUI TEST LCDPANEL then look with the oscilloscope at all the control lines and the data lines on the LCD connector of the E100. You should see some activity. - pulses from zero to 3.3 volts. I had a problem just earlier today where the MM pin used for D/C was a bad solder join and the signal at the LCD connector was a very noisy 1 volt - a give away to a floating pin. panky. ... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it! |
