@lizby I'm just using a 68R resistor to +5v. It's one I just had hanging around from a previous experiment. :) Hmmm... With a36 loaded all seems ok and Calibrate has worked.

Doesn't achieve anything. Tokenising a program kills memory so you couldn't then chain the program. Given that load x, flash save x is hardly onerous. There are differences in I/O e.g. use of SETPIN so there is no reason to make changes that break the link from the underlying H/W pin definitions I thought I'd fixed that in the recent releases? Sounds possible Not my objective for the PicoMite as an embedded controller. The PIC32MZ has all this, supports SSD1963 displays and is faster (including 64-pin version) - why replicate  Edited 2021-06-26 07:44 by matherp |

@mixtel90 Mick, in you Pico docs under a21 the entry line referencing TOUCH has IRQ and CS the wrong way round - this is from Peters 'Coming .....' entry so just a typo and long since bypassed but it caught me out. All other references seems to be good TOUCH cspin, irqpin [,beep pin]. Thanks for the Pico docs, they have been invaluable for me. Doug. ... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it! |

Thanks, Doug. I've fixed that now. Glad you've found it useful. :) Updated to a38: PicoMite docs a38.zip ** Any ideas folks? ** I *think* I might have found my problem with losing the SD card when T_CS is connected. The pullup on that signal is either missing or too weak. I've added a 10k pullup to 3.3v and reloaded a38. I can now read the SD card. Display is working. Touch calibration screen appears but same problem. This time I noted that *any* touch on the screen brings up the error message, whether in calibration mode or not, so touch is definitely being detected. Tried a 10k pullup (and pulldown just in case) on T_IRQ too but that's not helped. Swapped back to a36 and SD card, display & calibration all set up & work fine. Loaded a37. SD card and display are fine. Same problem on attempting calibration.

Thank you for this. I also had it T_IRQ, T_CS, and that was the reason I got no response to touching the target. Unfortunately, now when I touch the target, the response I get is not good: screen goes blank and: > gui calibrate Error : Touch not calibrated This is with an ILI9488--I'll try with the ILI9341. And as with Mixtel90, any subsequent touch gives multiple "Error : Touch not calibrated" messages--4 of them in my case. Tried again and got to the second target before getting the error. Tried again and got to the 4th target, but still getting the error after clicking it. After multiple further attempts which failed at various targets, it completed: > Error : Touch not calibrated > gui calibrate Done.

@matherp Is power now running in PFM or PWM? You mentioned in a35 that it's now permanent, but you didn't say which way. I assume it's PWM? OPTION POWER doesn't appear to do anything now (I'd never used it so I assume it disappeared at a35). I'm wondering if I have a power issue. I've ordered a powered usb hub just in case. This second Pico is very unreliable enumerating unless T_CS is disabled. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Default after option reset is PFM |

Thanks. It's not the extra load of PWM that's doing it then. Is there any way we could read ADC3 (VSYS) and GP24 (VBUS)? Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

@Plasmamac You should be able to remove the previous lcd setup using OPTION LCDPANEL DISABLE then enter a new configuration. You have to do this whenever you make changes to an lcd. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Using the pico which on which I had not been able to complete GUI CALIBRATE for an ILI9341, I plugged in a new ILI9488 and set it up. It took about 10 attempts at GUI CALIBRATE before it succeeded. Then I ran a guidemo.bas which had been modified for 480x320:  I tried SAVE IMAGE "gui480.bmp", but the file was all white--I guess because of the non-working status of MISO on the ILI9488 (I had snipped off the pin).

The 10 in SDCARD is the default speed of 10MHz. You can set it lower or higher to suit your particular card. Mine works fine at 15, I've not tried it any higher. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
