  1. Ok now that my hands are getting dirty I think I know why you said 10, cause there are 9 free di/do plus CS availible (44). true? thanks
  2. Its fixed, I was too agressive on trimming and averaging (mean)
  3. PMOD TC1 works with WF32 using Adapter Shield but I get some quantization noise, is this native to device , I use this with a labview driver? These flat bands happen at 0.25 C increments. I take about 1000 measuremtns , trim the lowest and highest 25%, then average the rest to one data point and then record this. Same math is performed on LMT86 (red), which is running on AI0 on the WF32. Wondering if it fundemental to the PMod TC1, otherwise its in labview driver. Thanks, Marty
  4. Larry, Thanks very much for your advice, I was thinking I just needed to monitor, buy now I see why you recommend the Aardvark. after reading your post I looked at the Saleae and was impressed with the software interface, one thing about TotalPhase is they tend not to show their software running in a screen size you can scrutinize. But now I realize I'm gonna need to put something on bus that communicates (as master or slave) inorder to write working code. Thank again, Marty
  5. thanks, I didn't see the Discovery having I2C and SPI knowledge. I did find another unit on the web: https://www.totalphase.com/products/beagle-i2cspi/ Opinions?
  6. I'll soon go thru the grind of learning I2C and SPI and writing drivers for my WF32 attachments. I did a brief search on the web but think asking hear might be more unbiased. So I saw this tool: http://www.tech-tools.com/DV509-logic-analyzer.htm And see that Digilent sell this: https://store.digilentinc.com/digital-discovery-portable-logic-analyzer-and-digital-pattern-generator/ I looking for an excellent analyzer for debugging I2C and SPI drivers I will write. I don't want to waste my time writing an analyzer driver cause I'm on a learning curve. Want something out of the box that actually includes I2C and SPI debug tools. Any suggestions, advice? thanks, marty
  7. Sorry ment chip select not SPI channel, when I get my stuff I'll play with changing chip select in labview to see what line toggles on the board
  8. Please correct me or comment. It seems the WF32 was only intended for the user to utilize ONE SPI external device. In section 10.2, a total of four are mentioned, though one is for wifi. BUT, when you look at the pin out table (section 12.3) SPI is only defined for one usage. My mistake obviously to assume you can scale up to more than one SPI channel with simple changes in code. Oh well, live and learn. If I'm wrong about this. Then will the labview software properly route SPI communication to SP2 if I define my SPI channel as 2?
  9. I'm going to program in LABVIEW, and I just ordered the PMOD shield. Labview has a PMod example for the PmodTC1 where you can set SPI channel and CS (chip select). Lets say I want to use five PmodTC1 (connect them to JA thru JE) 1) can use all five PMod connectors (4-GPIO and 1-SPI) to do this? 2) where are SPI channel and CS ( Chip select) configured on the board? thanks Marty
  10. How many PModTC1 units can run on a WF32? Thanks Marty
  11. Makerhub linx as I bought Labview physical computing with WF32. All my programing will be in LABVIEW. My house is fairly wired so I might try a USB to LAN extender, but a very reliable wireless is a good thing. Just did't get that good feeling with the WIFI connection. USB is robust. I'm new to these microcontrollers, so take that into account. Thanks very much for your ear and advice. Marty
  12. Fixed: I loaded USB firmware via Makerhub-Linx. I reinstalled Labview guessing it would clear the WIFI firmware because I thought this was causing issues with USB operation. I forgot, that USB firmware install was also a proceedure I followed when I initially set up. I will say unit operated nicely again. Will not load WIFI firmware.
  13. Unit now only reads AI about 200 times and then times out. Will return hardware. Is that fair?
  14. Should I assume that WIFI on the WF32 is just for playing around, not for a looping program that collects data for days or months? I ask because I Wrote a simple loop which blinks a few on board LEDs and then reads AI1. Prior to the loop you can choose WIFI or USB connections. Result: 1)USB seems to run forever with no error. 2) WIFI runs at best an hour before it errors and ends program operation. So I could go into my router and reserve the ip address within DHCP or move it out of DHCP and make it static. Also can prioritize communication to this IP address. hope I'm not talking to myself, Marty
  15. Sorry saw my question was answered already, guess WF32 is not very popular. Hmm does anyone have insight to the longevity of the Chipkit WF32, what I mean is it gonna get retired soon? thanks in advance.
