  1. Hello, I am having the issue that I do not see anything printed on the serial monitor in energia. I upload the code successfully and the port seems to recognize the board and did necessary updates, but there should be words printed on my serial port since I have my MSP430FR5994 connected to a sensor. Any idea why there is nothing there? I set the serial monitor to 115200 baud. I am trying to watch the sensor readings in real time. Maybe I just do not have a good understanding of how to read data from a serial monitor. Here is a copy of the code I am using which is for the Sparkfun heartra
  2. Hi folks! I am working on a project using an MSP430FR5994 through Energia 1.8.11E23 on Linux. As part of that project I would like to persist some variables, i.e. they are set once when the code is flashed and then if updated will retain the updated value upon power cycle, reset, etc. A simple counter example code I am using to test this is shown below. The desired behaviour is that the counter starts at 5 and then continues, and does not reset back to five even if the MSP is power cycled or reset. I have tried the existing undocumented PLACE_IN_FRAM (a macro for __attribute__((sectio
  3. hello, I need help, sorry for my lack of knowledge, just started with MSP430, I saw an example which I try to reproduce, writing on the micro SD card (SDHC 16GB). Upload is the code. how else am I suppose to define "FIL", am using the FATFS lib. . thank you for helping
  4. Hello team Energia I already asked the question for the serial port, and I never had an answer. There is also one of the simplest primitives that does not work: attachInterrupt() To work around the problem, I used gpio.h and gpio.c. But I would prefer to use the Energia functions. Can someone now look into these two issues? Can we hope!!!!!!!!!!!!! thank you in advance
  5. (Apologies for posting both here and on TI E2E forum) I am not able to use upper FRAM above 0x0001000 on MSP430 in Energia for an existing project, I am using latest Energia release E20 which uses latest version of gcc compiler 4.6.6. My goal is to 1) get the linker to locate two initialized data arrays in upper FRAM on MSP430FR5994 or MSP430FR5969 and 2) read that data as a lookup table using the Energia program. I have used the following attribute to map the arrays to upper FRAM: const unsigned char __attribute__((section(".fartext"))) Program_Data_IC_1[5120]= { 0xFF, 0
  6. I'm porting my compact Lisp interpreter, uLisp, to the MSP430FR5994 LaunchPad, and would like to provide SD card support. I've already got code working with AVR chips using the Arduino SD library. Is there a port of this to Energia, or something similar? Thanks, David
  7. Hello, How to define differential inputs in Energia for internal ADC of MSP430FR5994? Best regards, Adi
  8. Hi all, I have a potentially odd question. I am using and MSP430FR5994 board and would like to measure SRAM decay. However, whenever I toggle the system from on to off and then on again the locations in SRAM that I am reading are full of random of values. While I would expect random values, I would not expect them at the timescales that I have the system off. The system is off for no more than 10ms. According to https://spqr.eecs.umich.edu/papers/rahmati-usenix12.pdf that should be short enough where I get very little decay. I should also specify that the random values seem to be consiste
  9. Are there any plans to add support to Energia for the new MSP430FR5994 LaunchPad? It has a really nice specification including 256 KB FRAM, 8 KB SRAM, a maths accelerator, and an on-board micro SD card. It looks like an ideal platform for my small Lisp interpreter, uLisp.
  10. I have been trying to use a simple I2C sensor (LM75) with a MSP430FR5994. I find there are two pin maps. One at Energia (http://energia.nu/wordpress/wp-content/uploads/2016/11/Capture-2016-11-30-à-15.10.44.png) and one at TI directly (http://www.ti.com/lit/ml/slau677/slau677.pdf) on page 2. I have tried using I2C (1) as indicated at in the TI reference, and I have tried I2C (2) as indiicated in the Energia reference. neither one work. I can use an Arduino to access the sensor so I have some hope that this might work. What pins do I need to use to use I2C? Is there a library call to specify whi
  11. Hi, TI has a new launchpad MSP430FR5994 LaunchPad Development Kit based on the MSP430FR5994. The new controller is in "Preview" status , but looks interesting -- 256KB FRAM + 8KB RAM + a Low-Energy Accelerator for Vector Math Operations ( TI claims 35x Faster Than ARM Cortex-M0+ Core for 256-Point Complex FFT ). Check the app note Benchmarking the Signal Processing Capabilities of the Low-Energy Accelerator (Rev. A) for details. The launchpad itself is interesting as it has an on-board micro SD card and super capacitor. Has any one got hands on experience with this on
  12. Looks like TI have launched a new part, 256KB FRAM and 4 UART's a dream for me. Is Energia support available at launch? Happy to help out if not. http://www.ti.com/tool/msp-exp430fr5994 Great news or a very cruel April fool!
