  1. Kicking off my MSP430FR2433 hobby effort I looked into the RTC peripheral, which amounts to a really simple stupid counter, the likes of which I often used WDT for back in the day. It just counts up to RTCMOD and then fires the ISR. So without the fancy date tracking that RTC_B did on the Wolverine chips, I had to up the ante a bit and write myself a library to convert "epoch" seconds format (# of seconds since Jan 1 1970 midnight UTC) into a "struct tm" year/month/day/hour/minute/second/etc. structure and vice versa. I looked around for other implementations and found some inspirat
  2. I'm trying to use the UCA0 for SPI on MSP430FR2433 by using the SPI.setmodule(10); before SPI.begin(), but I'm not getting any data on the SPI lines. The default SPI on this launchpad is UCA1 and it works. After the above thing didn't work, I tried changing the core files: /home/username/.energia15/packages/energia/hardware/msp430/1.0.5/variants/MSP-EXP430FR2433LP/pins_energia.h In this file I changed: (from line 47 to 50) static const uint8_t SS11 = 8; /* P2.1 */ static const uint8_t SCK11 = 7; /* P2.3 */ static const uint8_t MOSI11 = 15; /* P2.4 aka SIMO */ static const
  3. I have been running into a problem recently with uploading to my board. Note, I am fairly new to this area of tech so I may be doing something wrong. I am currently doing an assignment for one of my classes that requires me to upload to my board and i keep getting the error message: Energia: 1.8.11E23 (Windows 10), Board: "MSP-EXP430FR2433LP" Sketch uses 274 bytes (1%) of program storage space. Maximum is 15360 bytes. Global variables use 2 bytes (0%) of dynamic memory, leaving 4094 bytes for local variables. Maximum is 4096 bytes. DSLite version 9.3.0.1863 Configuring Debugge
  4. I try to add support for a new mcu (MSP430FR2433) to Energia and would like feedback if this is the right way... The boards and variants files have been already been adapted. Because Energia uses GCC also I copied the msp430fr2433.h from the TI CCS directory: \ti\ccsv6\ccs_base\msp430\include_gcc\ to the Energia directory: \energia-0101E0017\hardware\tools\msp430\msp430\include\msp430fr2433.h But when I try to build the basic blink example I get errors like Looking at this line and comparing it to the already existing msp430fr413
  5. Howdy, I'm having trouble programming my MSP430FR2433LP with Energia on my Mac. When I try to upload the program, it gives me this error: MSP430: Error initializing emulator: No USB FET was found. Strangely, I am able to program it with the online Code Composer Studio. I have made it blink red and green lights. Unfortunately, I'm not trying to become an embedded programmer (while that would be fun, I do not have the time) so I do not want to learn CCS, registers, and serial communications in pure C. Props to all you who can do this. I really want this to work
  6. Hi, running this blinking led code on Launchpad MSP430FR2433 // Ultra Low Power Blink Example #define LED RED_LED void setup() { for (int i = 2; i < 20; i++) { if (!(i == 11 || i == 12)){ pinMode(i, OUTPUT); digitalWrite(i, LOW); } } } void loop() { sleep(2000); digitalWrite(LED, HIGH); // turn the LED on (HIGH is the voltage level) sleep(3); digitalWrite(LED, LOW); // turn the LED off by making the voltage LOW } resulting in this current profile: The power consumption looks nice (with LED current limit
  7. Hi, I'm working on a board with an FR2433, and also doing testing with the FR2433 Launchpad. I am trying to troubleshoot high current using SleepSeconds() With Suspend, I can get 1.5ua but sleep seconds is around 18ua, I believe it should be far lower based on the datasheet for LPM3. I am using a ucurrent gold so feel confident about the measurement. I set all my pins (1-22) to OUTPUT LOW and have also tried with INPUT_PULLDOWN Any assistance here would be greatly appreciated. Thankyou.
  8. Hi everyone, I am playing around with ePaper displays and wrote a library for them link, trying to reduce energy budget so far to allow self-powered, little devices with ePaper screens. Now I moved from several ARM-based MCUs to MSP430FR2433 launchpad to try benefiting from its low power modes. Getting the EPD to run with Energia worked almost out of the box. Getting low power (sleep) modes to run in Energia is my next goal. Cheers, Robert
  9. Hi, I posted a question on e2e but I found interesting to ask here too. I'm trying to port the Adafruit MCP4725 library to MSP430 using the Driverlib. I'm testing with launchpad EXP43FR2433 running at 1MHz and I would not want to use interruption to keep the code more portable. The sequence to write some value on DAC is relatively simple. - Set address -> send start -> send write cmd -> send upper byte -> send lower byte -> send stop. Using the following code one byte of the value is lost. msp43x_I2C_setSlaveAddress(EUSCI_B0_BASE, _i2caddr); ms
  10. Is Serial1 (pins P2.5/UCA1RXD and P2.6/UCA1TXD) available on the MSP430FR2433 from Energia? If yes, is Serial1 already pre-instantiated or do we need to create the object in the sketch from the HardwareSerial class? Thanks!
  11. Hi, I am trying to connect my MSP430FR2433 Launchpad to Energia. I do not see how to select this board in the "Tools -> Board" setting, and I do not see how to download the drivers for it in the board manager. Yet on the homepage of energia.nu, it states that support for this board is available. Does anyone have any suggestions on how to get this board to work in Energia? Thank you. -Grant
  12. Hello everyone, Yesterday I've got my new MSP430FR2433 Launchpad and I'm planning to launch myself into low-power MSP world with it. Wanted to check out what other enthusiasts and professionals are doing here. Would love to join the community and will definitely try to participate actively. Cheers from Baku, Azerbaijan.

  13. Hello, I am new to to MSP environment and I would like to have some help with this project. If this is on the wrong place of the forum or something like this please tell me so I can change it. I tried to make things on my own but I got stuck for 2 weeks trying to get my LCD to work properly with my first MSP. I also have acess to a friend's MSP430G2553, but the links some of the links on the forum where broken on http://43oh.com/2010/11/lcd-special-two-ways-to-interface-a-msp430-to-an-lcd/. The conections are most probably right because I can write without problems t
  14. Hi, The new MSP430FR2433 ValueLine Launchpad is with a promotional price. https://e2e.ti.com/blogs_/b/msp430blog/archive/2017/11/08/introductory-price-of-4-30-for-msp430fr2433-mcu-launchpad-kit?HQS=epd-mcu-msp-vline-fb-blog-LPdiscount-wwe&hootPostID=97a463d63a1e96cbf999f3c7a33c703e It seems to be a good replacement to the old ValueLine G2
  15. 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.
  16. In this post I reveal the applications of the new product I have been working on this last month. ChipStick is a tiny, low cost ($10) 16 bit microcomputer based on the MSP430FR2433 attached to a PC via a USB cable. It comes with up to 256K bytes of non-volatile memory - uniquely using ferro-electric memory. It has up to 16 accessible GPIO lines - which include a mix of SPI, I2C, UART, Timer and ADC channels. ChipStick may be plugged into a breadboard or stripboard and act as an intelligent programmable controller interfacing with other circuitry. ChipStick can also act as
  17. Last week, I put together a design for a lightweight dev-board using the MSP4302433, known as "ChipStick". ChipStick is a 20 pin DIL module that can plug into the socket on a G2 Launchpad. In the week whilst waiting for the prototype boards to arrive, I have prototyped the design using a SMT adaptor - allowing it to be built on a breadboard. Today I have refined the original concept, to produce a second design which, being small I have called Nanode (very small node). Nanode is effectively the same circuit as ChipStick, but trimmed to make a smaller form factor. The main diffe
