spirilis 1,265 Posted March 14, 2013 Author Share Posted March 14, 2013 Ok, as promised, design files for this revision of the F5172 LP: Top: Bottom: Schematic: DipTrace Schematic - F5172_LaunchPad_draft4.pdf OSHpark gerbers: OSH_F5172LP_draft4_0.zip Seeed/ITead/Elecrow gerbers: Elecrow_F5172LP_draft4_0_5x10.zip Errors: Labels for 5V and GND in the upper right region are reversed RefDes C14 and R8 are reversed TXD/RXD LEDs are backwards when a brand new FT230X is installed; reprogramming the FT230's EEPROM can fix that roadrunner84 and bluehash 2 Quote Link to post Share on other sites
roadrunner84 466 Posted March 14, 2013 Share Posted March 14, 2013 Why didn't you use the ez430 connector for the SBW interface? Quote Link to post Share on other sites
spirilis 1,265 Posted March 14, 2013 Author Share Posted March 14, 2013 Never used the eZ430 pinout myself, don't have any of its headers. That might've been a decent alternative solution but I always forget about it since I never use it. Quote Link to post Share on other sites

That might've been a decent alternative solution but I always forget about it since I never use it. At least you have the TI JTAG (FET) interface on it. :grin: The ez430 would allow you to use a regular launchpad for the programmer (a bit more easily) as it has the 6pin 1.27mm pins built in (just not the header) then again adding the femal connector on your end I'm uncertain what part they are off the top of my head (sad indeed). I obtained 6 pin to 6 pin female to female flex cables for doing this sort of thing for a msp430F5341 board (work related). The only issue with that is then you have the pins mirroed on the other end if you aren't careful (sigh). So you need the female header (heh). the Part SL127l6th I'm not sure who makes (I know I have 10 of them is all hrmm need to look into this). Unfortunately the pin out is definately not the same as the lauchpad. Anyhow I ramble ... (nothing new I guess) Cyb Quote Link to post Share on other sites

(nothing new I guess) Cyb Yeah in addition to that, I recall seeing a review by Jeri Ellsworth about the eZ430 where she mentioned plugging it in backwards can cause some nastyness (are Vcc & GND on opposite ends?), so that's another hit against the interface IMO. In either way, I kinda like my configuration here and the only awkward thing is how it makes the launchpad sit funny when it's not attached, but if you use stackable headers that problem goes away. The TI FET430UIF interface & tool is the only tool officially supported by TI for that chip anyhow. That interface is wired SBW too btw, not 4-wire JTAG. Quote Link to post Share on other sites

If you ever get bored try looking at this document from TI, section 1.2.3 covers the spy-bi-wire interface and timing. The high level API for the FET (msp430xxx.dll) is designed to work through the USB CDC com portinterface. They did this primarily to create linux compatibility with the interface. It is too expensive and legally difficult to use a proprietary driver for devices like that so they choose to reduce the propretary end of things. Cyb Quote Link to post Share on other sites

kenyee 5 Posted March 19, 2013 Share Posted March 19, 2013 Can the SBW programmer on this do a security fuse blow? That was the main limitation of using the TI Launchpad for me..ended up buying an Olimex programmer for that. Quote Link to post Share on other sites
spirilis 1,265 Posted March 19, 2013 Author Share Posted March 19, 2013 I don't think it's set up for that. It's meant to either use the TI LaunchPad as its SBW programmer, or use a FET430UIF tool to program it over SBW (it does NOT have a SBW programmer built in!). I understand there's some resistor you're supposed to incorporate when doing security fuse blow with the FET430UIF and I didn't include any of that. I intended this to be an eval/dev board for the F5172 so the user can go design a circuit around the chip. Quote Link to post Share on other sites
mbeals 74 Posted March 21, 2013 Share Posted March 21, 2013 Have you had a chance to play around with the timerD peripheral yet? I was reading up on it the other night and it seems to have some pretty nice features. Quote Link to post Share on other sites
spirilis 1,265 Posted March 22, 2013 Author Share Posted March 22, 2013 Not yet! I was going to try a sound experiment soon. I have some samples from Microchip (SRAM and serial flash) which I have been meaning to solder up to a board and use to store PCM samples for playback. Quote Link to post Share on other sites

spirilis 1,265 Posted March 30, 2013 Author Share Posted March 30, 2013 off topic question: Do you have the eagle footprint for the combo tuning fork/HF crystal? Sorry, I don't use eagle. I made separate footprints/components in DipTrace and incorporated them both in the schematic (then arranged them close to one another)... Quote Link to post Share on other sites
