I've had several cases recently where the info segments of the flash memory has gotten corrupted. By corrupted I mean that the data I though I had stored in the info segments was no longer there. Has anyone else here seen this or does anyone have any suggestions on how to avoid it? I've double checked the set up registers and the clocks and everything appears to be good. We are using an MS...

Hello: Does anyone has any experience with using the Atmel AT45DB642D Data Flash with the MSP430? Are there any drivers available on the net somewhere? We wouldn't like to re-invent the wheel:-) Our programmers have this idea: ---- I saw an interesting thing ... the clock supplied to the memory is not continuous. It's the SPI clock which is active only when sending smth from the ...

Hello All I am a newcomer to the MSP430, I would like to implemented a flash bootloader on the MSPF1611 using existing on UART to talk to an existing PC VB application via the serial link, so this would probably involve copying code to RAM and running a small bootloader from RAM. Has any one done this? If so is there any VB and/or MSP code examples? I have already got a VB application t

Hi all. I'm trying to store 3 char variables on the flash memory of an MSP430F123. These 3 variables must remain unchanged on power failure, so I can update a counter at power up. I'm using the C TI example fet120_flash_write.c changed for my needs, i.e., I don't clear the memory at startup, I point de Flash pointer to 0x1080 and write the char values on this address and the next 2....

Hi guys, I'm trying to record user button pushes to INFO Flash with the saveProgram() routine below. The first time the routine is called it works fine. The second time the routine is called it does not rewrite the locations. In fact, in some of the locations it writes in a zero. Stepping through the statements I can't find why it would do that, all the necessary registers seem to be ready w

For your information HCC-Embedded have released a development board for the MSP430 which comes with demo programs for creating reliable file systems in the internal flash, external serial flash and also PC compatible with MC/SD card system using minimal RAM. Also with the demo board is HCC's uCDrive software so you can connect your MSP to PC and it appears as a standard pendrive. Use y

Hi, I=B4ve been using msp430 for several years and for some months i=B4ve been experimenting in the use of c++ objects to see how the compiler deals with them. My question is: I have a class with some const variables inside which are initialized by the constructor (for example the size of a buffer). Is it posible to force the compiler to locate this variable in flash memory instead of ram?....

I am looking for help from anyone who has implemented digital audio stored in some type of flash and then "playe" out over DAC. I guess I have 2 questions: 1. how are people storing digital audio files (5-20 seconds 16 bit encoded)? 2. does anyone have experience (and examples) of taking that stored (in flash maybe?) audio and putting it out using the DAC? I appreciate anyone's help...

I am developing a system where I have to communicate through the SPI with a flash (ATMEL AT45DB081B) based on what value I obtain on one of my ADC12 ports. I am using the MSP430-149. Right now the system is set up such that the ADC has its own interrupt and if a certain value is hit - it sends an opcode out the SPI (SIMO) to the flash. This ends the ADC interrupt. The opcode though tells

I'm working with a MSP430F1121A chip and I have some problem with the data in the Information Memory Flash. I think that the flash timing generator frecuency is not correct. I can't measure the frecuency of SMCLK in the output pin 17 (P1.4) . In my code: P1DIR |= 0x10; P1SEL |= 0x10; P2DIR |= 0x01; P2SEL |= 0x01; On the pin 8 (P2.0/ACLK) I can see a square signal of 32 Kh

I've got a successful project operating using an MSP430F148 talking SPI to a flash card. The problem, however, is as follows: The prototype of the project has the flash card mounted very, very near the MSP430 (i.e. the MSP430 is sitting directly underneath the hollow part of the SD card socket), and it works great. On the device this gets installed in, however, the card needs to be accessi

Hi, I have a question about the calibration data in flash segment INFO A (MSP430F2xx devices). Are these values used "internally" (i.e. directly used by some modules) or only when explicitly accessed by my code ? That is, can I decide to store them somewhere else and store other data in INFO A instead, or is it mandatory to keep them in INFO A ? Thanks, -----------------------------------...

Having accidentally erased the calibration values from INFOA Flash. It sounds simple enough, that for simple convenience I'd ideally like to be able to restore the values I was careful enough to write down (for the ONLY board I'll be using), as a conditional build option. However, there appears to be a linker segment clash, I can't figure out how to avoid. It works links with predicta...

I'm trying out a crude DIY flash programming tool, without much success, and I'm wondering if anyone else has tried this. I have the USB stick development tool (ez430-F2013), which of course comes with a target board. The target board connects to the USB stick via four pins, which are connected to pins 1,10,11 and 14 on the MCU. What I thought I could do is make a cable that plugs into...

I ordered another LaunchPad from TI on Nov 29 and was pleasantly suprised when it arrived on Dec 2, populated with a 20-pin PDIP MSP430G2553, and a spare MSP430G2452. The G2553 has 16K FLASH, 512 Bytes SRAM, 2 16-bit timers, USCI_A (UART/IrDA/SPI), USCI_B(SPI/I2C), 8 Comparators, Temp Sensor, and 8-chan 10-bit SAR ADC. In other words, enough FLASH, RAM & peripherals to get into some fairly complex...
