  1. Hi to all, are you interested in assembler language programming? if so, this could be of interest to you. the basic idea is a 5kB kernel embedded on a MSP430FRxxxx, capable of downloading source files, interpreting and compiling them. Associated with a minimalist IDE: a text editor, a generic preprocessor and a terminal to communicate with the embedded kernel. What is the craziest wish of a microcontroller programmer? In my opinion, it would be that once his source is modified, he clicks on the "build" shortcut of the editor and in a second, the program is compiled on the targ
  2. I am having issue of the microSD card adaptor not initialing right, that is it does not successfully handshake between MSP432 and adaptor. I am using the SD.h library provided by Arduino and changed the pins mapping to the MSP432's MOSI, MISO, SCK, CS. However, this did not solve it. I even got an Arduino Uno and tested with the adapter and it showed that it was working there. Any help will be appreciated, as I have been suffering the internet regarding this issue for a while now.
  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. Hi everybody! Problem Description: I've been programming CC1352R platform lately. And I am realizing there are no many libraries for while. I need to implement the storage of my sensor data and I started to look for a library for using with an SD card. In the TI drivers, (from the SDK - Software Development Kit), there's a library SD.h. And in the examples folder for TI drivers there's an example which name is "sdraw". The first time I run this example It couldn't open the sd. First I sent a question on TI community: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/p/
  5. hello there, Ive been trying trying to interface an sd card to msp432p401r but i get many errors. my task is top build a data logger where the sensor readings will be stored in a text file. So i tried basics first. First i tired to serial print the sd card info but had lot of errors (screenshot can be seen below). the files i used is attached in the rar file "SD", in that i tried the Card info example. Please can someone help me what is wrong with this code. Thanks SD.rar
  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. HI EVERYONE, Long time no see. University has been hard, not time for anything. But I am back into the MCU world! And I am having some problems so I first would like to know if anyone ever tried this. I am using a SD card to save data with FATFS. The problem is that the MCU is also doing other stuff... I've been having writes of a few ms which is normal with FATFS. I am considering of course trying to write 512bytes at a time but also implementing DMA on the SPI. But I am not sure the DMA will help. It seems FATFS f_write and the port function disk_write, want to right away
  8. I am using micro SD card to log reading from four force sensors connected to the microcontroller (MSP430G2553). Controller logs reading to the SD card every 15 minutes and goes to sleep. I am using 1000 mAh battery, which is lasting over a week. Is it possible to reduce the power consumption as to make it last over a month. (#) Even if the microcontroller is sleeping for 15 minute, SD card is continuously consuming power. (#) It takes couple of mA to write. Help with any suggestion to reduce to power consumption drastically. Schematic and code (attached). Code_D
  9. Hello, I've been looking trough the forums for an SD Card Library that can be used on TM4C123GH6PM micro controller. I came across one (http://embeddedcomputing.weebly.com/microsd-card-boosterpack.html) but the link redirects to the forum main page, so I can't really get my hands on it. Does someone has a low resource library for this? Thanks! Note: In case this is good to know, I'm looking to use the SD Card slot that comes with the ILI9341 2.2" LCD screen sold (mostly) on Ebay. So we're talking about an SPI-Interfaced SD Card.
  10. I have been searching for a FatFs Energia library for the FR5969 a while and haven't come across anything that worked, so I decided to try make one. If there is one out there.... ahhhhhhhhhhghhghgh. The library is called Jaffl: Just another FatFs library It is located at: https://github.com/geometrikal/Jaffl Details: It is written for the MSP430FR5969, mainly because transmit and receive SPI bytes routines hard coded to USCB0. If someone can make this more generic it would be welcome. The Jaffl wrapper is based on the FatFs wrapper by David Sirkin. The latest FatFs version (
  11. Hey Guys, I am new user of Energia. Currently, I am using MSP430G2553 chip to write data in SD card. I found code that works on USCIB0 SPI communication. Here is the link for the code. This code works completely fine. But, I wanted to know how can I change the code to use USCIA0 SPI instead of USCIB0 to do this? I tried going into pins_energia.h and just changing the pins. But it didn't work. Can anybody help me with this problem? Here is port assignment for different SPI buses USCIB0: (Code is using it) P1.6 -> master in slave out (MISO) P1.7 -> master out slave in (MOSI)
  12. Hi, I am a novice to MSP430 so my prior apologies for asking basic or stupid questions. I am trying to interface SD Card with msp430f5529 launchpad using FatFS file system of elm-chen. Luckily I found some of the files on the github via google which included mmc.c, mmc.h, HAL_SDCard.c and \HAL_SDCard.h . I wrote the main file and somehow my SD card is being mounted but root directory is not being opened and I am always getting SD Card not ready message. I tried changing the card but it did no benefit. Can someone guide where is it going wrong and whats the way to resolve it. Let me know if
  13. I'm currently working on implementing the sd card code provided by the 43oh team to use with the breakout board I got. All of the examples I have seen are using the MSP430 of some variation. I am trying to use this code for application with an LM4F* launchpad or TM4C123 launchpad. Can anybody lead me in the right direction on what all I need to change in the code for proper interface. Has anybody accomplished this yet? The code that I have been trying to use can be found from this link: http://doc.43oh.com/The_Card_Reader_SDCard_BoosterPack The forum where I first discovered the
