After installing the firmware, the command OPTION LIST does not display the full list of assigned options, including the configured PS/2 keyboard on the default pins.When setting up options with pins for your circuit, sometimes you run into pins already used by the system. It would be nice to have a built-in command that provides information about the state of the pins. For example, this one PINS LIST Edited 2024-12-11 06:19 by javavi |

Something like Harms Freepins()?  Sub FREEPINS() Local integer n,p Local string gp$,pu$ For n=0 To 29 gp$ = "GP"+Str$(n) On error skip p = MM.Info(pinno gp$) If Not MM.Errno Then pu$ = MM.Info(pin p) Else p=-1 pu$=MM.ErrMsg$ EndIf Print gp$;@(50,MM.Info(vPOS)) p, pu$ Next End Sub I have integrated it into your filemanager.

Peter, After updating on an RP2350 with HDMI and USB on an Olimex module to PicoMiteHDMI MMBasic USB RP2350A Edition V6.00.01RC6, the serial port is not automatically reset after an option change, which means that all the nonsense appears on the screen the first time. By restarting the module and also TeraTerm, everything works fine again. (no beep from TeraTerm USB reset) One more point. What is SDS in the pin list with Boot Reserved : SYSTEM I2C SDS?

@Peter, In the last (2040 VGA RC6) version the logic analyzer DEMO mode does not work anymore. Demo mode uses the PIO to sample input pins GP0..GP5 and uses PWM output at the same time on these pins. For this purpose the pins are configured as PWM pins and NOT as PIO pins. PIO only reads the pins in the background. That used to work, but not anymore. I have confirmed that the PWM works on GPx pins. But PIO does not see these anymore. In fact, the PIO cannot read any input signals anymore. Not even when SETPIN GPx,PIO1 is performed. This seriously invalidates PIO. Volhout PicomiteVGA PETSCII ROBOTS |

Please try setting the pins as inputs. Pins default to OFF which turns off everything. Setting them as PIO enables them for output but not input. Edited 2024-12-12 19:22 by matherp |

Hi Peter, No, when setting SETPIN GPx,DIN the PIO also does not see input signals. Volhout PicomiteVGA PETSCII ROBOTS |

| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 9293 |
I'm confused. Are you physically wiring the PWM pins to the PIO inputs or are you assuming they can be read without wires? |

Hi Peter, The logic analyzer (DEMO mode) outputs PWM signals at GP0,1,2,3,4,5 (3 PWM's,6channels) as demo signals. In the background the PIO reads the pins GP0...GP5 and displays the signals on the logic analyzer screen. That did work (just confirmed my Pico is not dead by running 5.09.00RC5). But the essential problem now (RC6) is that even if I stop the PWM's, and configure the pins GP0..GP5 as PIO, or DIN, I cannot read anything in the PIO. PIO is disconnected from the input pins. Regardless SETPIN. I remember that in 5.07.xx you made a fix that allows PIO to read pin status regardless the SETPIN command. Maybe that feature got lost somewhere in the 6.00.01 series ? I remeber that I succesfully ran the logic analyzer in 6.00.00 series. MAy even be a toolchain issue ? Maybe in the pin direction/function register there is a bit that connects PIO directly to the pin, that got changed. I use this function (PIO can read, MMBasic can control) a lot to start and stop PIO state machines. I.e. in the frequency counter on GP22. MMBasic is set for DOUT, where the state machine uses this as gate signal. Volhout Edited 2024-12-12 19:56 by Volhout PicomiteVGA PETSCII ROBOTS |

When pins are set as outputs (e.g. PWM) the input capability is turned off. Therefore PIO can't read them (logically except for your demo purposes there is no real reason why you should be able to). If you set your PIO to read pin A and PWM on pin B and connect a wire between A and B it should work if A is set as an input (not PIO). I will make a change so that A can be set as an input OR PIO. |

Peter, If I connect GPx to a 3.3V power supply, regardless of what I do, PIO does not see a high level in 6.00.01b6. It is always 0. Regardless if I set pin to PIO1,DIN or whatever. PIO is deaf. About the capability of PIO to read pins when MMBasic drives them... - this functionality existed in 5.09.00 - it does not exist anymore - this feature is also used in the PIO chapter in the user manual (EXAMPLE PROGRAM 3). In case this functionality is lost, I need to carefully check and adapt that section before it is published. Volhout Edited 2024-12-12 20:15 by Volhout PicomiteVGA PETSCII ROBOTS |

Hi Peter, This is one of the first excersizes in the PIO training course 3 years ago. 'disconnect ARM from GP0. - 1000Hz / 1500Hz Square Wave SetPin gp0,pio1 'configure pio1 p=Pio(pinctrl 0,1,,,,gp0,) e=Pio(execctrl gp2,0,31) f=1000 * 6 'Hz 'line code comment ' 0 E081 SET GP0 output ' 1 E001 SET gp0 high ' 2 00C5 JMP (GP2=1) to 5, (skip instructions 3 & 4) ' 3 E001 SET gp0 high ' 4 E000 SET gp0 low ' 5 E000 SET gp0 low ' 6 0001 JMP to 1 'program pio1 PIO program line 1,0,&hE081 PIO program line 1,1,&hE001 PIO program line 1,2,&h00C5 PIO program line 1,3,&hE001 PIO program line 1,4,&hE000 PIO program line 1,5,&hE000 PIO program line 1,6,&h0001 'write the configuration (note we added "e") PIO init machine 1,0,f,p,e,,0 'start the pio1 code PIO start 1,0 'toggle GP2 in MMBasic SetPin gp2,dout SetPin gp8,fin Do Pin(gp2) = Not Pin(gp2) 'toggle pin GP2 'Print Pin(gp8) Pause 2000 Loop End It uses GP2 (MMBasic) to control the frequency of a tone generated by PIO. Potentially you can use GP8 (wire) to measure the frequency. But a speaker connected to GP0 is easier (audio). It is also tested on normal PicoMite (non VGA). Due to the bug, the output tone is 1000 (from pin 8 reading). On 5.09.00 the reading toggles between 1000 and 1500. Volhout P.S. you may need to set the CPUCLOCK to 133MHz...

The example gives the same issue. GP2 is an output so it isn't an input and can't be read. The PIN function gets round this by reading the state of the output latch but the PIO is trying to read the input itself. Again, if GP2 was being externally controlled in a real application the example would work. You can demo this by setting GP2 as an input and then connecting it to GND or VCC in which case the code works 'disconnect ARM from GP0. - 1000Hz / 1500Hz Square Wave SetPin gp0,pio1 'configure pio1 p=Pio(pinctrl 0,1,,,,gp0,) e=Pio(execctrl gp2,0,31) f=1000 * 6 'Hz 'line code comment ' 0 E081 SET GP0 output ' 1 E001 SET gp0 high ' 2 00C5 JMP (GP2=1) to 5, (skip instructions 3 & 4) ' 3 E001 SET gp0 high ' 4 E000 SET gp0 low ' 5 E000 SET gp0 low ' 6 0001 JMP to 1 'program pio1 PIO program line 1,0,&hE081 PIO program line 1,1,&hE001 PIO program line 1,2,&h00C5 PIO program line 1,3,&hE001 PIO program line 1,4,&hE000 PIO program line 1,5,&hE000 PIO program line 1,6,&h0001 'write the configuration (note we added "e") PIO init machine 1,0,f,p,e,,0 'start the pio1 code PIO start 1,0 'toggle GP2 in MMBasic SetPin gp2,din SetPin gp8,fin Do ' Pin(gp2) = Not Pin(gp2) 'toggle pin GP2 Print Pin(gp8) Pause 2000 Loop End |

This worked in 5.07,xx 5.08.00, 5.09.00, and not anymore. The RP2040 is capable. Something disables this function.  Maybe this is disabled in the new toolchain for compatibility to 2350. I will ask Geoff remove the applicable section in the user manual for 6.00.01. I will revert back to 5.09.00 since I need this function. Thank you for your support. Sorry to be such a problem maker... Volhout PicomiteVGA PETSCII ROBOTS |

There is something odd going on with regular DIN also. This command line test works on some recent firmware versions and not on others.
