Hi Martin, thank you for the code! I copied the program text out of your posting and pasted it in to the text file "maze.bas" - then I fired up MMEdit, loaded "maze.bas" and pressed F2 for "Deploy". After 5.3 seconds it was loaded into the RP2040. After that I take PuTTY to connect again and RUN the program. It feels like DOOM but where is the gun?   -andreas |

Hello Stan, as Mick told you there is a even better configuration. Currently I'm using this. > option list PicoMite MMBasic Version 5.07.07 OPTION SYSTEM SPI GP10,GP11,GP28 OPTION AUTORUN ON OPTION COLOURCODE ON OPTION HEARTBEAT OFF OPTION DISPLAY 50, 100 OPTION LCDPANEL ST7735S, LANDSCAPE,GP8,GP12,GP9,GP25 Micks procedure to get there: OPTION RESET OPTION SYSTEM SPI DISABLE SETPIN GP28 OFF OPTION SYSTEM SPI GP10,GP11,GP28 OPTION HEARTBEAT OFF OPTION LCDPANEL ST7735S, LANDSCAPE,GP8,GP12,GP9,GP25 -andreas |

Thanks Andreas, that worked ok and overclocking works ok. This would be nice for a beginner as there is no wiring for a display.  Edited 2023-06-08 10:10 by stanleyella |

Yes, this is a descendant of the version that I had running on the PicoGAME VGA. It's a pity you never added the T-Rex. Thanks for the program. Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Yes! The only thing I'm missing is wireless on the RP2040-LCD chip. So I'm using a second pico w as interface to the world. It starts to become a little computer in a matchbox :-) -andreas |

I tried to write simple scope code for waveshare 2040 with lcd but it's rubbish. Had better results with 328. Searched for scope code and not much. How many samples could I expect at 378000 ? Anyone made a picomite scope? This works... sort of, no sync. dim count% Dim samples!(160) Dim old_samples!(160) ' SETPIN GP26, AIN cls for count%=0 to 159 samples!(count%)=PIN(GP26)'get new samples next count% for count%=0 to 159 samples!(count%)=(samples!(count%)*20)+10 'scale 3V samples to 0 to 79 pixels next count% for count%=0 to 159 old_samples!(count%)=samples!(count%) 'copy samples to old_samples next count% for count%=0 to 158 line count%,samples!(count%),count%+1,samples!(count%)+1,1,rgb(white) 'draw first samples next count% '-------- do for count%=0 to 159 samples!(count%)=PIN(GP26)'get new samples next count% for count%=0 to 159 samples!(count%)=(samples!(count%)*20)+10 'scale 3V samples to 0 to 79 pixels next count% for count%=0 to 158 line count%,old_samples!(count%),count%+1,old_samples!(count%)+1,1,rgb(black) 'erase old_sample line count%,samples!(count%),count%+1,samples!(count%)+1,1,rgb(white) 'draw new sample next count% for count%=0 to 159 old_samples!(count%)=samples!(count%) 'copy samples to old_samples next count% loop end |

Use the ADC command and you will get up to 500,000 samples per second |

Hi Mathew. Thanks but replaced reading pin for command and NOT the same, if it does anything. 'SETPIN GP26, AIN adc open 1000,1 cls 'for count%=0 to 159 'samples!(count%)=PIN(GP26)'get new samples adc start samples!(160) 'next count% I tried adc start samples!() and no display "The size of the arrays defines the number of conversions." so dim samples!(160) is 161 samples Edited 2023-06-18 06:52 by stanleyella |

Look at Volhout's posthere |
||||
| stanleyella Guru Joined: 25/06/2022 Location: United KingdomPosts: 2129 |
Cheers but I don't see the relevance. From the manual it should fill the array with samples, or maybe not. To add joy I can't get pwm working setpin gp2, pwm 1 pwm 1,1000,50,50 RUN [8] PWM 1,1000,50,50 Error : Pin not set for PWM I'm using gp0, gp1 for sound. I wanted to drive the scope with a wave from tone then try from pwm. |

You can always recover a pin before doing something else with it: SETPIN GP0, OFF ADC keeps reading the pin and putting it into the array, at the speed you set. It does it in the background so it's very fast. Once the array is full it stops running, so you can plot that array then restart the ADC for the next set of points. Follow Volhout's code for the ADC: Set the ADC frequency (he's used formula because of what he's doing. You don't need to) Dimension a float array for the number of samples. ADC open adc_freq, 1, ready_int opens the ADC for 1 channels and trigger interrupt when array is full. ADC start array!() starts the ADC run and stores the values. DO:LOOP We do nothing here, just wait for the ADC. END At the end of the scan the interrupt routine runs. You plot the values here. Sub ready_int ADC close .... .... End Sub You'll have to tweak things a bit because you want to keep re-trigggering the ADC after each plot, I suppose. For a scope you would often use a Trigger input to start the scan. Or you can keep triggering it automatically after each plot. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
