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 ( -
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

I know I haven't finished off my desk clock project just yet, But I've been requested to design a new GPS logging device for my sisters Beagle Club, The basic idea is that a sent is placed with a guy that forms a path, the GPS logger is taken along also. They then attach the device to a beagle (using some kind of vest, I think). And let them follow the scent. Post event they extract the GPS data from the logger and overlay both tracks in google earth. They have one unit that has been working well for them, developed by a previous club member. It consists of off the shelf c

Hello, I have used petit FatFs library in my project and it is working great but only problem is It can not create new file it only can modify already created file. But in my project I need to create many files on runtime. where can I ger FatFs SD Host library which I can use with energia. Thanks in advance -
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

Hi, I had interface MSP430F5529 launchpad with FatFS Sd card. I was trying to store value from ADC into SD card and I found that I cannot store the value on SD Card, unless I do "sprintf" or equivalent printf of the data, only then I was able to store the value on SD card. However, sprintf is expensive command and takes more cycle then ADC output i.e some of the data is lost from ADC in doing sprintf. Is there a better alternative than sprintf or something like if I store raw value and later post process it? Any help will be highly appreciated. Thanks

Hi, I am trying to compile ELM Chen FatFs and I am getting identifier error in ff.h (line 157) for typedef struct DIR in code composer studio. It also leads to a type specifier error on line 215,216 and 217 which uses this identifier. Any help to sort it out will be highly appreciateable. The errors are below: Description Resource Path Location Type #41 expected an identifier ff.h /SD_Up2 line 157 C/C++ Problem #80 expected a type specifier ff.h /SD_Up2 line 215 C/C++ Problem #80 expected a type specifier ff.h /SD_Up2 line 217 C/C++ Proble

https://github.com/jmagnuson/fatfs-tiva-cm4f/blob/master/src/third_party/fatfs/port/mmc-tiva-cm4f.c It's still a work in progress, but should be a working drop-in replacement for the MMC driver TI provides. I've only done minimal testing on it thus far, so any corrections or improvements would be greatly appreciated!

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 was looking to interface FatFS to the MSP430G2744: It has 1KB of ram (may be enough? If not I might look into using the MSP430G2755 with 4KB of ram) I've been hacking away at getting it interfaced after doing Petit FatFS and realizing I needed to have resizable files and file creation (oops).... and that Petit has already been ported (double oops). I've been able to get it to compile with GCC, here's the FatFS branch of the project. But things are not running smoothly anymore, after I upload the code the LEDs are dim and it doesn't seem to execute past my little serial loggi
