you should make some way to add a harddrive or storage disc to it so you can store data on it and use it like a terminal like from fallout that would be another cool thing for you to post. Die zweite Generation stellt der SCC (Codename: Rock Creek) dar. Before I can include an SD card holder on any future version of the single chip computer, I need to test altering this file to output to an attached TV rather than over serial. This computer system runs TinyBASIC just like my Arduino BASIC Shield but this project is completely standalone meaning no Arduino is needed and only a single AVR is needed. is a single-board computer crowdfunded by now-defunct Next Thing Co. (NTC), released as open-source hardware running open-source software. 6 years ago The PCB would also be double sided, removing the need for the jumper parts and possibly use some surface mount components to reduce its size. I've always been very impressed with your project.I do have one question. Deutschlands reichweitenstarkes Portal für News, Downloads, unabhängige Tests & Kaufberatung. Der Prozessor besteht aus 24 Einheiten, die mittels eines gitterförmigen Netzwerks verbunden sind und darüber miteinander kommunizieren können. The reason I ask is because if so I see no reason why one would not be able to utilize a much larger eeprom to have a larger storage area for multiple programs. and called it MEOW 1! The last picture shows some of my old programs in BASIC, saved to paper as saving them on tape was unreliable on my unit. It was a great unit, that offered me and others using it, endless possibilities for learning early programming techniques. So is there a way I can connect an lcd screen and mini keyboard like these. I got a PCB from him directly (he has a few on sale on Ebay), then purchased the components and finally soldered everything together. If a PCB is not used, different components may be needed as some have footprints such as the RCA socket which cannot be placed on strip-board) Additionally, tools are needed to construct the PCB including a soldering iron, solder, needle nose pliers and wire cutters. on Step 1. I had to alter the RAMEND value in TinyBASIC Plus in order to allow enough memory for the video buffer required by TVout and I also changed the break key used in TinyBASIC Plus (it was previous CTRL+C) because control keys are not supported by this PS2 keyboard library (I used the escape key instead). The standard PS/2 keyboard library clashes with TVout causing strange output to be shown on the TV and the keyboard not being read correctly but, after some research, I came across a library known as PS2uartKeyboard which uses the XCK0 pin and RX0 pin of an AVR to connect to the keyboard in order to allow a PS/2 keyboard to work with the TVout library. Diese Seite wurde zuletzt am 14. NMEA GPS Library for Microcontrollers -2-, Tube: SI-22G (CИ-22Г) Sensitive Geiger Muller, http://dmitry.gr/index.php?r=05.Projects&proj=07.%20Linux%20on%208bit. very nice, thanks for sharing this! The images of the blue PCB are for the second version of this computer (details for this board can be found on Hackaday projects: https://hackaday.io/project/1260-single-chip-avr-basic-computer, Update (07/12/14): I updated the design of the computer by adding an additional EEPROM IC allowing full size BASIC programs to be saved. NTC has since gone insolvent. This single chip computer has a video output via RCA, allows a PS/2 keyboard to be connected, allows circuits and components to be connected using the IO headers and runs the TinyBASIC programming interpreter. Downloads. The circuit is fairly simple as the ATmega 1284P has the minimum hardware connections required (along with a 16MHz crystal) to operate along with the TVout connections (RCA socket) and the PS/2 keyboard connections (mini din socket) The TVout pins are PD5 (for sync) and PA7 (for video) and the PS/2 keyboard pins are PD0 (for data) and PB0 (for clock). CHIP and related products are discontinued. Single Chip Computer. nevermind about the lcd screen I think it would be smarter and easier if I use a car back up moniter instead, Sorry I guess the pictures never showed up here are the links, http://www.hessmer.org/blog/wp-content/uploads/2015/06/LCD1602Display_I2C-Front.jpg, http://themodshop.net/wp-content/uploads/2012/01/rii-mini-wireless-keyboard-1.jpg, and one more thing the keyboard is wireless using a usb dongle. If you’ve seen the about section of my blog, you know that I was trained as a software developer. Hello, i have a small issue with a code it still gaves me these errors : class TVout' has no member named 'select_font, class TVout' has no member named 'set_hbi_hook', In function 'void outchar(unsigned char)', 'class TVout' has no member named 'print'. Alternatively, EEPROM ICs could be used (e.g. So all in one, the future’s … They can be used for educational or demonstration purposes, development, embedded computer controllers or … Stiu ca acel integrat are ceva conexiune pe seriala ma gandesc sa il leg de un max 232 si sa imi ofere seriala sau poate aveti voi niste idei mai bune ! Der Single-chip Cloud Computer (SCC) ist ein experimentelles Prozessordesign, das in Forschungseinrichtungen der Firma Intel entstanden ist. This circuit and the software running on the microcontroller, offers USB Keyboard support, RCA Video signal output (connectable directly to a TV, like the original ZX Spectrum units), and a BASIC Interpreter (namely the tinyBASIC). Taking advantage of all these improvements are the applications, and we’re seeing an increasingly larger number of those as well. Pe mine m-a costat mai mult 1284-ul, si PCB-ul. But from what I can tell you did this in lieu of an SD card. Posted By Radu Motisan on October 17, 2014. I have attached the PCB as etchable PDFs (which were generated using Fritzing) as a ZIP archive on this page. Ein-Chip-System), auch System-on-Chip, versteht man die Integration aller oder eines großen Teils der Funktionen eines programmierbaren elektronischen Systems auf einem Chip (Die), also einem integrierten Schaltkreis (IC) auf einem Halbleiter-Substrat, auch monolithische Integration genannt. I may also get this first version of the single chip computer produced using a PCB service which allows a coloured PCB, silk screen and through-hole plating which would remove the need for the jumper parts and give a more professional look to the computer system. The PCB could be optimised in certain ways such as making it smaller by moving the components (such as the female pin headers around the ATmega 1284P) closer together and if a double sided PCB was being used (with features such as through-hole plating), the jumper parts could be removed. thanks. Ubuntu pe un 1284 ca si al meu: http://dmitry.gr/index.php?r=05.Projects&proj=07.%20Linux%20on%208bit. When compling the sketch in the Arduino ERW IDE, the sketch size is less than 22KB and the estimated SRAM usage of the AVR is nearly 9KB (leaving around 8KB for the TVout video buffer). Varianta de BASIC curenta am scris-o direct in Flash-ul uC, e vorba de tinyBASIC, compilat pentru AVR, cu suport pt video out si tastatura usb. The unmodified version of TinyBASIC Plus uses the serial port of the AVR to allow users to interact with the software and create programs. The TinyBASIC Plus sketch can be found attached on this page.
