A question about the standalone programmer issue please. I want to improve my board by adding a programming jumper. According to zeke's schema above, he hooks up the jumper to pins 10 and 11. Will this work with the G2452? I have seen advice suggesting pins 2 and 3 :? Also, is there freeware that will enable me to make schemas easily like zekes? Thanks for reading. KB

Thank you both for listening and caring. I was afraid this was beyond my comprehension, but the last post ties everything together nicely These forums have been the best resource I can find, and has pushed me to learn things I never thought I could understand. KB

getting complicated, but i want to understand this. Using CCS probably isn't helping get this going. I am working on getting that windows.h and VS files at the moment. thanks for the impetus!

I will try it on my laptop if i cant get it to work after one more try. What is confusing me is the lack of direction in the post. Using the smartie directions, it calls for the http://lcdsmartie.sourceforge.net/port95nt.exe driver. In the setup, i set the correct LCD, but dont know which driver to choose on the list, or which settings to use. 9600,n,1 is what i understand the LP likes. I understand the code utilizes the USB port, and I am assuming the LP should be in run mode, so it is waiting for data from the USB connection. Does this sound logical?

Hi bluehash. No, I am using Vista32. I have heard about these problems. I think I am missing something mundane, as I mentioned I saw the smartie data broadcast for a brief moment.... Please advise the steps you guys took. Thanks. KB

Hello All. I'm having a little trouble getting my lcd to work. It flashed on as i scrambled through the example, but i lost it. Can somebody explain the sequence please. I wired it up, compiled and flashed the c code. I have the nice "hello" but i cannot seem to interface with the software. Following the smartie directions it needs port95nt.dll. Is this what I should be doing? Thanks. KB

The nightmare is over. After finally making a plan and working out a new board, being careful with everything and checking it twice, I can see the light. P1 resistors enabled. The help is greatly appreciated, and the button debounce works flawlessly (no extra ints). Resistors enabled on P1.0-P1.3. Working with those connected PCBs it not worth it in my opinion, although the product is very appealing to the eye. I will improve on the board with a jumper for programming next..... :

Here are some late night drawings, I will work on some better ones tomorrow... Thanks Using MSP430G2452, detail per aforementioned wiki example Anyone have a schematic program that is free? PCB artist was ok, but schamas were difficult to understand for me :roll: J1=button harness J2=LED Array

I am going to try and enable the resistors. A while back this helped me with a bouncing problem. I have hardware debounce now, but I am going to give it a shot. I have checked off everything on your list zeke. I have been programming it on the LP and then hooking up my wiring harnesses to the LP to test it- working fine, I move the chip to the PCB. I am thinking now the problem is with my buttons. I based them on the demo: http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_PushButton It must be the debounce circuit. Curious why it works fine on the LP and not on the PCB

Adding a .1uF capacitor has not had any effect

thanks zeke, that Is a great reference. All seem to agree on the cap, which i will add momentarily. Can you tell me what OR means please. I am going to include a jumper as you show so that I do not need to keep switching the chip out (it was on my todo/tofigureout list ) P.S.- how do you put the images directly in the post. I tried the button (Img) above, and put in the link, but it didn't do anything. Thanks again. Ken

thanks oPossum and RobG, I will try the capacitor...

Thanks RobG, I fixed that mistake. One of these days I will get the terminology right. The resistor is hooked up as you suggested

As many nightmares evolve, I find myself alone in a state of terror with my MSPG452 project. I look to you guys for some comfort I have a basic input/output project that functions perfectly on the stock launchpad... The code is not the issue, the problem lies in my lack of EE experience... I have been working at this for about 6 months (learning and getting favors from my friend the programmer) : https://docs.google.com/leaf?id=0B0GvwGrWV7TpMmYxZTJiMWYtODFhYy00MjBhLTg0ZmMtMjEzYTk0OTQzZDk2&hl=en_US&authkey=CKuFiLsL I picked up some expensive FR4, they are pretty and

Totally cool. I am putting off purchasing one until i get i bigger itch, heck of a deal if anyone wants to try this project! http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... K:MEWAX:IT

A while back there was a problem with the newly issued G2 chips. It ended up being a software issue which was fixed eventually. As I waited, I experimented with other chips and formats, trying to get one of my ideas going. Here are some pictures of the TSSOP adapter I made to program them with the launchpad. I ended up using it recently to miniaturize my project, providing a standalone MCU platform with the TSSOP G2452. My soldering has improved, please don't comment on that. I have named it "Tron" for obvious reasons. https://docs.google.com/leaf?id=0B0GvwG ... 2&hl=en_US KB

Thanks Bluehash. I will share it when I get it under control, you helped me get it rolling as I was breaking into PWM with the MSP430...

I had to buy some extra Biometal Helix material, so i have some on ebay if anyone is interested: http://cgi.ebay.com/Biometal-Helix-Actuator-Wire-Free-Shipping-U-S-/290560494464?pt=LH_DefaultDomain_0&hash=item43a6c14b80 Thanks. Have Fun!

That was a perfect C+ for idiots reference question, sorry to waste your time. Now I just need to figure out how to format the output of the sqrt() function. I need it to be an integer. Thanks for reading

Hi All, I am working on a program for the MSP430 which requires a little bit of trig math. How do I get CCS happy with using the SQRT() function? Has anyone had success with this? Thanks

The unit with which I had problems prior to upgrade was #101001479.

yes you are right, i just received some 252's and with the firmware upgrade, works like a charm. no excuses now.....

I really had my hopes up this time MSP430: Trouble Writing Memory Block at 0xffe4 on Page 0 of Length 0x2: Could not write device memory Cannot write to target Thanks anyhow

which code did you use? please let me see, I had some delivered after the 17th that do not work on my 1.4 using CCS. thanks

Hi Sean, looks good. What docs did you utilize to get this working?
