Google Groups is being recalcitrant these past couple of days, so I have no idea if the world will see this, but I've just released free C source to my embedded FAT filesystem. I've tested this code on a variety of platforms, including ARM, AVR and MSP430. I know there are several such filesystems in the world, but this one meets my particular requirements for functionality vs. footprint - ...


MSP430, simulate reset (for a software bootstrap loader)

I cannot use the MSP430 ROM BSL, because the custom board, already in production, has a connector with the UARTs signals (not the hw BSL signals), and we cannot make hardware changes (it is a pity we cannot configure the hw BSL signals). To run the my BSL I only modify the reset vector, set = 0xF000. So at reset the MSP430 starts my BSL. It waits a bit for a firmware upload at the UARTs, a...

I'm working on a project using a TI MSP430. The compiler/IDE tool (IAR) wants to run on Windows. To download new flash code, it want me to use zmodem protocol over a serial line.

I'm working with the ms430-449STK2 olimex development kit that IAR distributes with its software, "XT2 = 8Mhz" The problem is that I can't select the XT2 as a clock source for the MCLK.

The TI MSP430 looks like an interesting chip. The low power operation allows 16 bit adc onchip. Now they seem to be doing the sort of things that microchip did in the past such as free seminars and low cost development tools. Like most companies, we have a lot of software written for other microcontrollers, but we will certainly look at TI for new designs. www.ti.com/ez430

Hi, I am using MSP430F1101 with a 32.768kHz crystal. I have 100 samples fabricated but I find that 20% of them could not start. At the beginning of the firmware, I have a loop to lock the DCO frequency to 2MHz using the external 32.768kHz as reference. I suspect the MSP430 cannot lock the DCO and stay in the loop forever. Did anyone have this problem before? Thanks for your help! Fei...

Everyone, Earlier I posted some macros that allow you to easily define binary constants in C (see http://cprog.tomsweb.net/binconst.txt).

It's written for the MSP430 but the concept can be applied to other embedded architectures. You simply define your signal lo...
