Post by thread:[SX] Look for schematic of simple SX chip programm

In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Valio wrote:Please share schematic of simple programmer for SX28 Previously I use PonyProg, but unfortunately it doesn't support SX architecture, so if possible, I want to build simple programmer, that doesn't require another processor inside like Fluff offer. I seen simple drawing of SX-TIPS and a lot of mentions about Parallax free programmer offer, unfortunatelly they removed all links to that and any info.

I heard that SX-Key of SX-TIPS feeds from COM port and have discrete element design, but maybe im wrong. Anyway look plz here: http://minsk555.narod.ru/jdm.htm or here : http://www.geocities.com/SiliconValley/Station/7733/ Besides Ubicom prev. offer simple programmer: http://www.ubicom.com/techdocs/appnotes/index.html (link removed) here some pictures: http://www.electrosnab.ru/ubicom/Ubicom_4.htm ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=351313#m351321 Need assistance?

The USB SX-Key uses the FTDI chip as a USB to Serial interface. So it is still serial even though it uses a USB port. Bean.

Can you advice, if I can use this quartz HCMOS/TTL generators: http://www.chipdip.ru/library/DOC000053903.pdf[\url] I can buy it locally. they have 50, 60, 80 MHz Or I have to use exactly Parallax 75 MHz TTL Oscillator ? Should I pay inside US delivery (Boston) if order on site ? PS: Plz, send me links for Fluffy and Fluffy2 schematics diagram.

In SX Microcontrollers, SX/B Compiler and SX-Key Tool, bean wrote:That clock should work. It doesn't have to be 75MHz. There are several SX designs that use 80MHz (like the XGS Pico). If you can have it delivered to Boston and have someone forward it you that would be alot cheaper I suspect. Just google for "Fluffy programmer" for schematics. Bean.

The in circuit debugging will save your sanity. I tried to tough it out with the emulator, and it is VERY nice, but the in circuit debugging can't be beat and is worth a lot more then $30. I went hog wild and got the PDB, and i have no regrets. I still use my fluffy to program these little sx28's on circuit boards, but i do all my testing with the sx key and a dip sx28, and it is wonderful.

Here is my page with info on my fluffy, its mostly for myself, but maybe you will find it of use: http://www.hellspark.com/dm/ebench/sx/howto.html ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=351313#m351488 Need assistance?

In SX Microcontrollers, SX/B Compiler and SX-Key Tool, robotworkshop wrote:It looks like the Fluffy programmers would be closer in features to the SX-Blitz if you mainly are looking at a method for programming the chips. For $30 the SX-Blitz is a good value and you keep the 4-pin header that has become the standard for programming these chips. If you plan on programming quite a few of the SX28 chips one thing you can do is get one of the SX28 protoboards, remove the SX28, and install a ZIF socket. It has the 4-pin header on board. That is what I use for those and it works well.

In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Valio wrote:Ok gentlemen, thanks for explanations ) Now I have some questions: 1) Maybe someone advice me the schematics of SX-Key - cuz page on Parallax with that info was deleted: http://www.parallaxinc.com/html_files/sxtech/sxtech_home.htm and prev. (as I can see on web) this schematic was free for download and repeat for self-made. 2) If I buy SX-Blitz or SX-Key, what other types of microcontrolles I can program ? Propeller maybe ?? 3) I looked on sxlist schematic of LCD + 4x4 keyboard and cant find it attached on the same unit, but on separate scheme they unfortunately share the same ping of SX28. In general I need 2 row LCD + 4x4 keyb + 1..2 ping as output. Could you plz refer for similar project ? PS: plz forward 2 sales - Can I place order for UPS/DeutchePost delivery around the world ?? How much it costs.

Both the SX-Blitz and the SX-Key are specific for the SX processor. 3) Not clear what you want. What schematic? Most of these smaller LCDs use the same controller chip, particularly the 1 and 2 line displays. It should be just a matter of using a 2 line display with the same controller (HD????). E-mail sales () with the details of your questions.

In the sxlist I found subprogram and code modules for LCD and k/b connection, unfortunately their schematic uses crosses in use of the same pins, so its impossible to use those modules both as. My question is - maybe someone could share (code+scheme) project that help me develop my device. Thanks. PS: What a programmer uses Propeller, the same as SX ?

The Propeller chip may be programmed with a direct serial connection, however it is usually done with the Propeller Plug, which provides a USB/Serial interface with the FTDI chip. See the Propeller Datasheet for schematics of both. If you would like to look for a Parallax distributor in your country, see this page.

In SX Microcontrollers, SX/B Compiler and SX-Key Tool, PJMonty wrote:Valio, The SX-Key (and later the SX-BLitz) are the simple COM programmer you are talking about. SX-Sim is built into the IDE. When you are developing code and want to run it through SX-Sim, all you have to do is press the button on the right of the toolbar that says "SXSim" (a bit hard to read I'll admit) or acess it via the menu at Run->Launch SX-Sim. The IDE automatically creates the LST file and launches SX-Sim with the LST file.
