brelliott18 2 Posted February 15, 2017 Share Posted February 15, 2017 Trying to use I2C to connect 2 X MSP430. Using Wire.write ('H') and 'L ' char to send to Slave via 4K7 pull-ups to turn on / off slave led. Using Wire.onReceive(receiveEvent) , void receiveEvent ( int howMany ) etc. Have added delays at various places. Have programmed then removed PC connections, use separate PSU ReceiveEvent appears not to work. Have old analogue scope - clock /data signals appear to be ' very dirty ' and ' noisy ' Change to 10K pull ups ? Any suggestions ? Thanks Quote Link to post Share on other sites
