Hello, I'm currently trying to interface my MSP430F248 with a CAT25256 EEPROM. Right now I'm attempting set the WEL (Write enable) bit on the EEPROM by sending the appropriate command. I load the command onto UCA0TXBUF and set the CS bit to start the transfer. According to the EEPROM datasheet, the MISO pin should be at high impedance while WEL is being set. I'm assuming since I'm not receivin...

I have an EEPROM chipset (AT24C1024B) interfaced with MSP430F248 through I2C UCB1 module. I'm able to write data to EEPROM but I'm not able to read back from it. First, I write the offset address to EEPROM before reading from it. After transmitting the last byte, I disable the TX UCB1TXIE, clear UCB1TXIFG flag, change to I2C receiver ~UCTR, enable RX UCB1RXIE, then I issue a repeated start ...

Hi Folks, I am attempting to write/read a Microchip 24FC1025 eeprom using the intrinsic i2c on a Texas Instruments MSP430F5438A chip. This may be a mistake because I got no hits when searching the Microchip forum for msp430 or F5438. Has anyone done this successfully and, if so, what are the pitfalls to watch out for? It is my understanding that this eeprom has two slave addresses...

Hello, I bought the Olimex EasyWeb2 Development board to learn the msp430 and I'm just trying to get every peripheral on the board to work one at a time. I finally got to the eeprom, but am having many problems.

Hi Group- I'm hoping to tap into your various experiences regarding a specific application I am being asked to consider: We would like to support a legacy device that in the past was simply an EEPROM (25LC320 SPI compatible 4K bytes). It holds sensor calibration data. When a sensor is connected to the smart sensor host, the host reads the EEPROM data. Now we want to make the senso...

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...
