CCS/MSP430F67641: MSP430F67641 Three-Phase Energy Measurement source code for CCS

James,
Thanks.
1. But I have not IDE of IAR, I don't kown where can get this IDE?

2. Use MSP430 headers (*.h files) to simplify code development.
CCS is supplied with files for each device that define the device registers and the bit names.
TI recommends using these files, which and can greatly simplify the task of developing a
program. To include the .h file corresponding to the target device, add the line #include
<msp430xyyy.h> for C and .cdecls C,LIST,"msp430xyyy.h" for assembly code, where
xyyy specifies the MSP430 part number.
I use chip is MSP430F67641IPN, but I do not find this file MSP430F67641.h in driverlib, should I use which one file to replace MSP430F67641.h?

Thanks and best regards

Hello,

You can download IAR from the following link.

The DriverLib project should include (under the "inc" folder) a header file called 'hw_memmap.h'. This file (shown below) includes a call to the 'msp430.h' header file. Using the device chosen when creating the project, it will automatically select the correct header file such as 'MSP430F67641.h'.

James,
Thanks.
1. But I cannot download IAR IDE,because I haven't the licence.
2. For the source code of three-Phase Energy Measurement system, whether can provide use notes? so that I can use these code to my application.
Thanks and best regards

For the source code of three-Phase Energy Measurement system (slaa621c), whether can provide its use notes and some Flow chart? so that I can use these code to my application.
Thanks and best regards

James,
Thanks.
But still some issue for use UART_2. UART_A2 cannot enter interrupt function.
For P2.2 and P2.3 as a UART_2, I use same configure and interrupt ISR code same as UART_1, but cannot enter this interrupt funtion ( ISR(USCI_A2, USCI_A2_isr)).Refer below.UART_2 interrupt is not response. but UART_1 is normal. I modied these use slaa621c source. Pls help.

ISR(USCI_A2, USCI_A2_isr)
{
uint16_t tx; //Lucy can enter router

switch (__even_in_range(UCA2IV, USCI_UART_UCTXCPTIFG))
{
case USCI_NONE:
break;
case USCI_UART_UCRXIFG:
uart_rx_core(2, UCA2RXBUF);
break;
case USCI_UART_UCTXIFG:
tx = uart_tx_core(2);
UCA2TXBUF = tx & 0xFF;
if (tx & 0x8000)
UCA2IE &= ~UCTXIE;
break;
case USCI_UART_UCSTTIFG:
break;
case USCI_UART_UCTXCPTIFG:
break;
}
}

James,

Thanks.

I done some modifications for use Uart_2 (See attached), after I modify the code, I rebuild all the projects in this order after making changes to any files: emeter-toolkit-67641 -> emeter-metrology-67641 -> emeter-app-67641,but still don’t enter the break point, see the attached.

Use IC: MSP430F67641IPN (80pins)

Thanks and best regards

Lucy

 

UART1 and UART2 break point.docx

 

James,

Any update?

This is urgent for me.

In our application, need use these two functions,UART_A2(p2.2,p2.3) and B0_SPI (P1.7,P2.0,P2.1),but cannot right working,I use TI provide UART and SPI example of code add to slaa621c source , Cannot enter their interrupt entrance.When I only buld UART and SPI example code ,they are right.How do I add these two function to slaa621c source? pls advise.

Thanks and best regards

Hello Lucy,

I would encourage you to use the original source code (unmodified) as a reference for your code. First, try to understand how the UART_1 is being initialized, configured, and used before moving to UART_2. Focus on the UART interface before moving onto the SPI interface.

Have you been able to debug the UART_2 configuration code in 'emeter-communication.c'? This code configures the UART_2 interface. If you can't halt on Line 270, then you'll need to figure out why the "UART_2_SUPPORT" define isn't configured properly. After this code is executed, the interrupts should be enabled. Personally, I've found that it helps to use the search feature in IAR (Ctrl + Shift + F) to go from defines to functions, etc. to understand the code better.

One more thing, if you're debugging, please be sure to turn off the compiler optimizations (both size and speed). I've found where this causes problems when debugging if not done.

James

Also, be careful which UART ISR you're trying to debug (there are several that depend on the type of module). Here, the MSP430F67641 has EUSCI_A2, so this module's ISR code starts on Line 664.

James,

ThanksUART1 and UART2 register.xlsx

I use original code and build it,URAT_1 is working.Then I add define UART_2 same as UART_1 below,
#define UART_2_SUPPORT
#define UART_2_BAUD_RATE                            9600
#define UART_2_DLT645_SUPPORT
UART_2 can right configure and can enter line 270 break point,But UART_2 still cannot working.I check and compare their registers,find out UCA2IE=0,its value has been modify,UART_2 cannot interrupt,refer the attached. Where can I restore its interrupt enable?
(One more thing, if you're debugging, please be sure to turn off the compiler optimizations (both size and speed). I've found where this causes problems when debugging if not done.) I don't find out where can turn off?
