I am having trouble with setting up i2c with the TM4C1294 as the master sender and the MSP430 G2553 as the slave reciever. The master seems to only be sending the address (Scope.jpg). The master_TX.txt file is the code for the TM4C1294 and the slave_RX_Configuration.jpg is a screen shot of the Grace i2c configuration for the slave recieve and the slave_RX.txt is a copy of the InterruptVectors_init.c for the MSP430 g2553. What am I doing wrong? [[View:http://e2e.ti.com/cfs-file.ashx/__key/communityserver-discussions-components-files/908/2705.master_5F00_TX.txt]

* ======== USCI A0/B0 TX Interrupt Handler Generation ========
*
* Here are several important notes on using USCI_A0/B0 TX interrupt Handler:
* 1. User could use the following code as a template to service the interrupt
* handler. Just simply copy and paste it into your user definable code
* section.
* For UART and SPI configuration:
if (IFG2 & UCA0TXIFG) {
}
else if (IFG2 & UCB0TXIFG) {
}
* For I2C configuration:
if (IFG2 & UCA0/B0TXIFG) {
}
else if (IFG2 & UCA0/B0RXIFG) {
}
* 2. User could also exit from low power mode and continue with main
* program execution by using the following instruction before exiting
* this interrupt handler.
*
* __bic_SR_register_on_exit(LPMx_bits);
