cde 334 Posted October 29, 2010 Share Posted October 29, 2010 So I tested out my i2c explorer with proper wires, and another part (Eeprom, can read, and can write the page address, but can't write to the eeprom. It's either write protected, or I fried it from a voltage/soldering issue. Hmm.) Works great on the i2c pcf8574a port expander. Been using it to get a hd44780/ks900su lcd working (it does!), and plan on releasing a msp430-i2c lcd backpack. Problem is that the MSP430G2231 has only 2k of usable code space. The i2c explorer clocks in at 1940bytes, so I can't add more to it (IAR is giving me issues writing more than 1950 bytes btw.). So, I was thinking of ways to cut down on code, and the only thing I can think of is turning the UART into a RX only one. Except I can't figure out how to chop up NJC's code in half. If we can, then we would have TX only, RX only, and TX&RX uarts, a complete set for any project! Any help? Quote Link to post Share on other sites
