<p>CRC - Build Signature and Rebuild to test.</p>
<p>The CRC is first used to build a signature using a seed and multiple data values. This signature is considered as the checksum and can be sent by a UART connection along with the data to verify the correct data has been sent. The second half of this program is used to test the CRC checksum of the data that has been created, by recreating the same checksum and comparing it to the first checksum. If the two checksum are equal, then P1.0 is set and the LED is turned on. Breakpoints can be set before the CRC_setData() function to observe the CRC register values and see the subsequent signatures before/after each data set.</p>

<p>DMA - Repeated Block Transfer to-and-from RAM, Software Trigger.</p>
<p>A 16 word block from 1C00-1C1Fh is transfered to 1C20h-1C3fh using DMA0 in a burst block using software DMAREQ trigger. After each transfer, source, destination and DMA size are reset to initial software setting because DMA transfer mode 5 is used. P1.0 is toggled during DMA transfer only for demonstration purposes. ** RAM location 0x1C00 - 0x1C3F used - make sure no compiler conflict ** ACLK = REFO = 32kHz, MCLK = SMCLK = default DCO 1048576Hz</p>
<h2><a class="anchor" id="autotoc_md38"></a>
Tested on MSP430F5529, MSP430FR5739</h2>
<p>/|| XIN|- | | | 32kHz &ndash;|RST XOUT|- | | | P1.0|-&gt; LED | |</p>
<p>This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:</p><ul>
<li>DMA peripheral</li>
<li>GPIO Port peripheral</li>

<p>USCI_A0, SPI 3-Wire Master Incremented Data This example shows how SPI master talks to SPI slave using 3-wire mode. Incrementing data is sent by the master starting at 0x01. Received data is expected to be same as the previous transmission. eUSCI RX ISR is used to handle communication with the CPU, normally in LPM0. If high, P1.0 indicates valid data reception. Because all execution after LPM0 is in ISRs, initialization waits for DCO to stabilize against ACLK. ACLK = ~32.768kHz, MCLK = SMCLK = DCO ~ 1048kHz. BRCLK = SMCLK/2</p>
<p>Use with eusci_spi_ex1_slave code example. If slave is in debug mode, P1.1 slave reset signal conflicts with slave's JTAG; to work around, use IAR's "Release JTAG on Go" on slave device. If breakpoints are set in slave RX ISR, master must stopped also to avoid overrunning slave RXBUF. </p><hr />

<p>This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:</p><ul>
<li>SPI peripheral</li>
<li>GPIO Port peripheral (for SPI pins)</li>
<li>UCS peripheral</li>
<li>UCA0SIMO</li>
<li>UCA0SOMI</li>
<li>UCA0CLK</li>
</ul>
<p>This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.</p><ul>
<li>USCI_A0_VECTOR </li>

<p>SPI slave talks to SPI master using 3-wire mode. Data is received from master and data from slave is then transmitted back to master. USCI RX ISR is used to handle communication, CPU normally in LPM4. Prior to initial data exchange, master pulses slaves RST for complete reset.</p>
<p>Use with eusci_spi_ex1_master code example. If the slave is in debug mode, the reset signal from the master will conflict with slave's JTAG; to work around, use IAR's "Release JTAG on Go" on slave device. If breakpoints are set in slave RX ISR, master must stopped also to avoid overrunning slave RXBUF.</p>

<p>EUSCI_B0 I2C Slave TX multiple bytes to MSP430 Master</p>
<p>Description: This demo connects two MSP430's via the I2C bus. The master reads from the slave. This is the SLAVE code. The TX data begins at 0 and is incremented each time it is sent. A stop condition is used as a trigger to initialize the outgoing data. The USCI_B0 TX interrupt is used to know when to TX. Tested on MSP430F67791A </p><pre class="fragment"> /|\ /|\

<p>This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:</p><ul>
<li>I2C peripheral</li>
<li>GPIO Port peripheral (for I2C pins)</li>
<li>SCL2</li>
<li>SDA</li>

<p>This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.</p><ul>
<li>USCI_B0_VECTOR. </li>

<p>This example shows how to configure the I2C module as a master for single byte reception in interrupt driven mode. The address of the slave module that the master is communicating with also set in this example.</p>
<p>Description: This demo connects two MSP430's via the I2C bus. The master reads from the slave. This is the MASTER CODE. The data from the slave transmitter begins at 0 and increments with each transfer. The USCI_B0 RX interrupt is used to know when new data has been received. ACLK = n/a, MCLK = SMCLK = BRCLK = DCO = 1MHz </p><pre class="fragment"> /|\ /|\

<p>Description: This demo connects two MSP430's via the I2C bus. The master reads from the slave. This is the SLAVE code. The TX data begins at 0 and is incremented each time it is sent. A stop condition is used as a trigger to increment the outgoing data. The USCI_B0 TX interrupt is used to know when to TX. Tested on MSP430F67791A </p><pre class="fragment"> /|\ /|\

<p>This example shows how to configure the I2C module as a master for multi byte transmission in interrupt driven mode. The address of the slave module is set in this example.</p>
<p>MSP430F5xx_6xx Demo - USCI_B0 I2C Master TX multiple bytes to MSP430 Slave</p>
<p>Description: This demo connects two MSP430's via the I2C bus. The master transmits to the slave. This is the MASTER CODE. It cntinuously transmits an array of data and demonstrates how to implement an I2C master transmitter sending multiple bytes using the USCI_B0 TX interrupt. ACLK = n/a, MCLK = SMCLK = BRCLK = default DCO = ~1.045MHz </p><pre class="fragment"> /|\ /|\

<p>This example shows how to configure the I2C module as a master for single byte transmission in interrupt mode. The address of the slave module that the master is communicating with also set in this example.</p>
<p>MSP430F5xx_6xx Demo - USCI_B0 I2C Master TX single bytes to MSP430 Slave</p>
<p>Description: This demo connects two MSP430's via the I2C bus. The master transmits to the slave. This is the master code. It continuously transmits 00h, 01h, ..., 0ffh and demonstrates how to implement an I2C master transmitter sending a single byte using the USCI_B0 TX interrupt. ACLK = n/a, MCLK = SMCLK = BRCLK = default DCO = ~1.045MHz </p><pre class="fragment"> /|\ /|\

<p>This example shows how to configure the I2C module as a slave for single byte reception in interrupt driven mode. The address of the slave module is set in this example. EUSCI_B0 I2C Slave RX single bytes from MSP430 Master</p>
<p>Description: This demo connects two MSP430's via the I2C bus. The master transmits to the slave. This is the slave code. The interrupt driven data receiption is demonstrated using the USCI_B0 RX interrupt.</p>

<p>USCI_A0, SPI 3-Wire Master Incremented Data This example shows how SPI master talks to SPI slave using 3-wire mode. Incrementing data is sent by the master starting at 0x01. Received data is expected to be same as the previous transmission. eUSCI RX ISR is used to handle communication with the CPU, normally in LPM0. If high, P1.0 indicates valid data reception. Because all execution after LPM0 is in ISRs, initialization waits for DCO to stabilize against ACLK. ACLK = ~32.768kHz, MCLK = SMCLK = DCO ~ 1048kHz. BRCLK = SMCLK/2</p>
<p>Use with eusci_spi_ex1_slave code example. If slave is in debug mode, P1.1 slave reset signal conflicts with slave's JTAG; to work around, use IAR's "Release JTAG on Go" on slave device. If breakpoints are set in slave RX ISR, master must stopped also to avoid overrunning slave RXBUF. </p><hr />

<p>This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:</p><ul>
<li>SPI peripheral</li>
<li>GPIO Port peripheral (for SPI pins)</li>
<li>UCS peripheral</li>
<li>UCB0SIMO</li>
<li>UCB0SOMI</li>
<li>UCB0CLK</li>

<p>This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.</p><ul>
<li>USCI_A0_VECTOR </li>

<p>SPI slave talks to SPI master using 3-wire mode. Data is received from master and data from slave is then transmitted back to master. USCI RX ISR is used to handle communication, CPU normally in LPM4. Prior to initial data exchange, master pulses slaves RST for complete reset.</p>
<p>Use with eusci_spi_ex1_master code example. If the slave is in debug mode, the reset signal from the master will conflict with slave's JTAG; to work around, use IAR's "Release JTAG on Go" on slave device. If breakpoints are set in slave RX ISR, master must stopped also to avoid overrunning slave RXBUF.</p>

<p>This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:</p><ul>
<li>SPI peripheral</li>
<li>GPIO Port peripheral (for SPI pins)</li>

<p>MPY - 32x32 Signed Multiply Accumalate</p>
<p>Hardware multiplier is used to multiply-accumalate a set of numbers. The first calculation is automatically initiated after the second operand is loaded. A second multiply-accumulate operation is performed next. Results are stored in RES0, RES1, RES2 and RES3. SUMEXT contains the extended sign of the result.</p>
<p>ACLK = 32.768kHz, MCLK = SMCLK = default DCO</p>

<p>MPY - 32x32 Unsigned Multiply Accumalate</p>
<p>Hardware multiplier is used to multiply-accumalate a set of numbers. The first calculation is automatically initiated after the second operand is loaded. A second multiply-accumulate operation is performed next. Results are stored in RES0, RES1, RES2 and RES3. SUMEXT contains the extended sign of the result.</p>
<p>ACLK = 32.768kHz, MCLK = SMCLK = default DCO</p>

<p>MPY - Saturation Mpode Underflow Test</p>
<p>Description: The example illustrates a special case showing underflow. Underflow occurs when adding 2 negative numbers yields a positive result. By having the saturation mode enabled, the result if rounded off to the highest negative number (0x8000.0000 for 16 bit). Results can be viewed in the debugger window.</p>

<p>MPY - Saturation Mode Overflow Test</p>
<p>The example illustrates a special case showing overflow. The addition result of 2 positive numbers may exceed the highest positive number (0x7FFF FFFF for 32 bit result) due to overflow indicating a negative result. By having the saturation mode enabled, this result can be truncated off to this highest positive number. Results with and without saturation mode are shown.</p>
