Hi to all, I am using softbaugh's ES449 board and having some difficulty with the SST eeprom. I have downloaded their sample code for sst from softbaugh's site and added my own functions. The WriteByte routine is working correctly, however it does not work when called succesively, e.g. SST25VF_WriteByte(0, 0x12); SST25VF_WriteByte(0, 0x34); SST25VF_WriteByte(0, 0x56); SST25VF_WriteByte(0

I am trying to implement access to a bunch of peripherals (RTC, EEPROM etc.) using I2C. I also have TimerA running. There is corruption of Read data from EEPROM. Without TimerA it works fine (so it seems). I have Googled and see that there indeed seems to be some issue with I2C and TimerA. Has anyone had experience with this problem? Thanks. ------------------------------------

Hello, I am using the EZ430RF with C2000 for talking with a Microchip 24FC1025 I2C EEPROM. As I understand from the datasheet, the MSP sends an address byte as soon as you set the flag for transmission of the start condition. The R/W bit that is the last bit of this byte and it being zero indicates that MSP is in transmitter mode. However, the EEPROM wants the last bit of the address...

Howdy y'all, I've succeeded in getting the red EZ430 board--that which ships as part of the RF kits--to work under Linux. To do so requires flashing both the 24c32 EEPROM and the MSP430f161 of the board with the firmware of their green-board equivalents. Flashing only the EEPROM results in a device which works with the present TUSB3410 kernel driver, but which is incompatible with gdbp...
