 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

TinyBasic on the ATTiny85 including digital read/write, analog read/write, DS18B20 support and tones. Program can be save in the in-built EEPROM and run on power-up All implemented in 8K flash and 512 bytes of RAM and EEPROM   |

I've got my Uno and ATTiny85 Arduino programming shield sitting right here. I suspect, however, that's not the way you're going to have us do this :-)  Edited 2023-07-25 09:45 by NPHighview Live in the Future. It's Just Starting Now! |

Looks like we might have a challenger to the 8-pin PICAXE chip. Watching this thread with interest.  Smoke makes things work. When the smoke gets out, it stops! |

UMM SOO VERRY COOL matherp, But can I request the addition off a command for servos or Stepper control PLEASE I may be Vulgar, but , while I'm poor, I'm Industrious, Honest, and trustworthy! I Know my Place |

Which flavour/speed of tiny85 can you use? Any of them? Most of these are out-of-stock due to the ongoing chip shortages. If you are willing to use QFN package, they have plenty(several thousand), but most of the SOIC and DIL packages are out of stock till October 2024! The usual story..... The DIL version shows 11 chips available from the 27th(they'll get gobbled up pretty quick I would say), then no more DIL till the above October 2024 date.  Microchip Direct Link... 4000 SOIJ package available from early next month. Perhaps Peter has another source for the chips he got he would like to share. Smoke makes things work.

You all must be aware , .and have forgotten about it. But Tinybasic is , TINY. Only 26 integer variables (16 bit) and no strings. And with 280 bytes free your programs are small. I have tinybasic on UNO, with 900 bytes RAM and even then, it is a challenge. It will just hold the 4 squares program. Nice for a programming Challenge through, and as a statement that it can be done. PICAXE 08M2 is in a different league. Volhout Peter: you can use program memory better if you allow to abbreviate commands ( they are stored in ascii). In the command parser, add 2 lines that allows to use the abbreviation with a ".". So PRINT becomes P. and DREAD becomes DR. The dot alse is terminator, so you can skip the trailin whitespace. Edited 2023-07-25 15:28 by Volhout PicomiteVGA PETSCII ROBOTS |

The first PICAXE 08A chip only had 128 bytes of memory for your program. I am pretty sure that the next model up, they dropped the "A", and the standard PICAXE 08 chip then had 256 bytes of program memory. TinyBasic still has more then that if you have 280 bytes to play with!   Smoke makes things work. When the smoke gets out, it stops! |

Farnell are showing ATTiny85-20PU (20MHz 8k 8-DIL) as 26,333 in stock. It might take us a week or two to put a dent in that. 1.644 UKP each incl. VAT. Eeeeh.... I remember Li Chen Wang's Palo Alto Tiny BASIC! :) It was the first BASIC I ever used. Well, a version of it anyway. 10 F.I-1TO10 20 P.I*I 30 N.I Might have been how I'd have written it at the time. Every byte was precious so there were no spaces or comments unless you *really* needed them. :) I wonder if this supports the (one and only) array @() which is automatically dimensioned to use all the spare memory?

Not sure about the efficiency of the PICAXE pre-compiler. If we could "tokenize" tinybasic program you may be right. But the standard tinybasic interpreter stores the code like this: - 2 bytes (16 bit hex line number) - the whole line in ASSCII characters - <CR> Tokenizing would translate "PRINT" in a single byte code. I see use for TINY85 as a peripheral to a larger mite. If it has PWM (analog write ?) you could do this 10 A=AREAD(2) 20 AWRITE 3,A 30 DELAY 1 40 GOTO 10 This would translate an anlog (ADC) voltage into a PWM signal that could be passed through a standard opto coupler to make an isolated analog input to CMM2 or PICO (i.e. measure mains voltage safely). Smart peripheral... Volhout PicomiteVGA PETSCII ROBOTS |

I had to retype lines (under NASBUG and T4. NasSys handled editing much better). It's not much of a pain as you can only have one statement per line so they are rarely long. These things are more of a 555-Turbo but without the high current output stage. About 3x the cost of a NE555 and fit the same socket, but rather more versatile. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Mixtel90: A friend made a line of toys that used hand-soldered 555 or 556 circuits, along with capacitors, resistors, photoresistors, LEDs, and tiny, tinny speakers. Each assembly took an hour or more of intricate soldering. I programmed (in Arduino) all of the functionality of all of his toys into a single ATTiny85 (getting all of it into 5 or 6 i/o pins was a challenge), provided him with an Uno, a programming shield, and a tube of 85's, all to no avail. I guess he was so set in his ways that he couldn't conceive of doing it any other way. Oh, well. Live in the Future. It's Just Starting Now! |

The picaxe 08M2 now has 2048 bytes of program memory and 128 bytes of ram Bill In the interests of the environment, this post has been constructed entirely from recycled electrons. |

Seeing this I went and rechecked a big box from a friend that did STEM for kids after school. Sadly he passed away and family thought I'd make use of it all. A few tubes of ATTY85 and ATTY84 a sub-box of 20 or so blue pills and what may be black pills too. Over 50 nano's and a few with a USB pcb that plugs in. 16 channel PWM boards, motor controllers so much more even motors too. Also a bunch of ESP32 boards I didn't see first time I look i the box. Many variations of Arduino's. I've played a bit with some just following a few youtube/online projects. What basic's are good to have a play with on the mix of chips/boards. A FUN find is a few BASIC-STAMP boards. Quazee137 I will need to make time to explore all this now. Edited 2023-07-26 12:17 by Quazee137 |

Hi Quazee, It should be obvious that you are appointed to continue the STEM activities. With all these materials it would be a waste if they would not benefit the kids. Take the box, visit the nearest school, and offer your services. I bet you are great at it, and with the help of this forum you can't go wrong.. Volhout PicomiteVGA PETSCII ROBOTS |
