Hi Everybody, I noticed that TI is running a deal on the new FR2433 LaunchPad board. Over on their blog, they posted a coupon code to drop the price from $9.99 down to $4.30. It looks like the limit quantity is 2x. After that, they are regular priced. I bought two today.

We are using Energia 17 with the MSP430FR5969 iand we now need to utilize upper block of FRAM at 0x10000 for storage of an initialized byte array because our program size has increased beyond the 48k in lower FRAM. I've modified the linker command file to locate the ".upper.rodata" section in "far_rom" at 0x010000 and declare the array as follows: const unsigned char __attribute__((section(".upper.rodata"))) Program_Data_IC_1[4096} = { <byte values here> } However, after modifying the Energia linker command file and rebuilding the Energia project (in CCS 6.1.3) the

Hi everyone. I was looking through the Energia library (cores/msp430/twi.c) today trying to debug an issue I have been seeing, and noticed the following code: /* Work around for: * If the master does a read and then a write the START interrupt occurs * but the RX interrupt never fires. Clearing bit 4 and 5 of UCBxCTLW0 solves this. * bit 4 and 5 are however marked as reserved in the datasheet. */ UCBxCTLW0 &= ~0x18; Does anyone happen to know why this is? I have searched high and low for a reference on TI's forums and in their documentation to no avail. Thanks for the help!

Hi Guys, My name is Nathan. I've lurked around here on 43oh a bit, but this is my first official post. I've been working with the MSP430FR5969 for several months now and I've quickly grown to really like it. It seems to me TI's FRAM processors should really be getting more exposure for battery powered development in both professional and maker communities. To that end - I was hoping to get some feedback on a product idea. We've packaged the FR5969 into a tiny coin-cell powered module. The module can operate as a stand-alone processor or it can plug into an UNO-form-factor breakout

Sorry to bother if I'm missing something obvious in the documentation - but there's something I can't seem to figure out. I'm migrating a simple datalogger that uses an ATTiny24a, BMP180, and an external EEPROM to (hopefully!) take advantage of the power savings and FRAM on the MSP430FR5969. I've attached a sample of my code by I can't seem to find anywhere similar functions to EEPROM.read and EEPROM.write. All I've managed to find is FRAM_write<enter # of bits here> in the fram.c in the DriverLib library. Basically all I'm trying to do is log data to the FRAM at a s

Hi All, My company is interested in developing passive sensors that are capable of harnessing energy from the environment, so basically the sensor are completely dead and without power until there's either light, temperature difference, vibration, or RF illumination. So I do not care about high current draw in sleep mode. In this type of environmentwhat would work best? MSP430FR? or M0+? Current draw during start-up on the MSP430 is also a problem, which is roughly 1 ms. Looking at the EMF32 Zero Gecko, Its list as 400us with a 24MHz clock. It seems to me that Zero Gecko would be a

Hi All, I'm attempting to get an SD card working with the MSP430FR5969 (launchpad) and FatFS but I'm having a difficult time. Two questions: 1. Is it possible to get FatFS working with the MSP430? When I did a search of these forums I mostly saw PetitFat being used with MSP430s. Ultimately, PetitFat would be okay but I would prefer FatFS. 2. Has anyone gotten either PetitFat or FatFS working with the MSP430FR5969? If so, would you be willing to share your code or knowledge regarding it? Thank you in advance for any help, Nipun

I'd like to write to FRAM on a MSP430FR5739 with Energia, Does anyone has an example? Thank you, Stephane

Recently there was a contest for applications using TI's ESI hardware rotation/flow sensing peripheral, I was one of the winners of that. Actually TI did a pretty cool thing and gave the prize (target board and programmer) to everybody who entered rather than just their favorite five. Go TI! In any event, here is product pitch I submitted: I also submitted a more advanced version that ties into the fuel injectors and computes instant and average mileage, but I may or may not get to that in a reasonable time period. This is my project thread for this project, if you hadn't gues -
Using the FRAM as though it were RAM on the msp430fr59xx chips can make it really easy to drive those ws281x chips even at a relatively slow MCU clock rate. The ws281x chips are great because you can get a boat load of leds for the cost of only one pin. Also, it doesn't hurt the price of these ws281x chips keeps falling and making them more and more attractive. I decided to see if I could take advantage of FRAM to help me drive some of those leds. I ended up with an extremely simple driver routine that works great even when you clock the FRAM MCU @ 6MHz. You couldn't really do this on a RA

Just as an FYI - I was concerned about using the built in DCO in the FR5969 for UART because the spec sheet says although it's factory trimmed, it's still +/-3.5%. Generally it needs to be within 2% for a UART to work correctly so I measured the two FR5969's I have on our 2.4GHz frequency counter and this is what I got. 2 is obviously not a big sample size, but the frequency trimmed DCO on the FR series looks pretty good @ room temp and 8MHz or under. I found another doc from TI that's a comparison between F5xxx and FR5xxx and it mentions the DCO is generally within 2% "within a restrict

I tested the lauchpad FR5969 with the new version of energia. After having changed both HIL.dll and MSP430.dll files in the directory E: \ ENERGIA_V13 \ energia-0101E0013 \ hardware \ tools \ msp430 \ mspdebug, I managed to correctly program the FR5969 launchpad. Searching the memory.x file in the E: \ ENERGIA_V13 \ energia-0101E0013 \ hardware \ tools \ msp430 \ msp430 \ lib \ ldscripts \ msp430fr5969, I saw that the compiler does not take advantage of the characteristics of FRAM which allows sharing of 64 kbytes memory between program space and ram space. Indeed it currently use -
Hey all, just wanted to share some code and a sweet picture of a QR code that was generated on an msp430fr5739: I'm working on a larger project that needed this functionality so I thought a proof of concept before I got too far into this was in order. While the pixels on the LCD I'm using (Nokia 5110 / PCD8544) aren't quite square, this code scans fine on my phone (Nexus 4). Anyways it uses the qrduino library to generate the code and some pcd8544 library for the lcd display. I briefly attempted to get this running on a g2553 but didn't quite manage it. The code is at https://

I recently bought a Fram board and a CC3000 for a small project. I have Code Composer already but wanted to try somthing new and ran across Energia. So I installed it and fired it up. I selected CC3000FirwareUpdate project to get started. Selected the FraunchPad w/ msp430fr5739 board in the Tools menu. Then I hit the Verify button... "Error compiling." c:/energia-0101e0011/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld.exe: CC3000FirwareUpdate.cpp.elf section `.rodata' will not fit in region `rom' Regards Ken

Hey all! I have received an email from the Official MSP430 Blog where they announce a Holidays offer. They are taking 54% off the regular price for just this last two weeks of the year!!! So if you always wanted a Chronos or a Fraunchpad and the price tag was your restraint... now you have no more excuses. Woohoo!!! http://e2e.ti.com/blogs_/b/msp430blog/archive/2013/12/17/get-a-chronos-for-christmas-or-an-fram-experimenter-39-s-board.aspx I just bought my very first Fraunchpad, and the discount code works... and I'm feeling tempted to get another Chronos... mmmmmmmmm Gast

I was poking around on ti.com today, and I was pleasantly surprised as I noted two product families that are now public. The datasheet and user-guide dates are not super-new, but there has been little fanfare and somehow I missed it. Maybe the reason is because I've spent the last 6 months working mainly on Cortex-M. But anyway... 1. RF430F5978 I have been working with this for a long time, in private (i.e. there are libraries and board support in OpenTag). It's really cool, because it combines a CC430F5137 with a 134kHz passive RF IC. One cool app you can do with it is wireless char
