Part Number: MSP430F6721
Tool/software: Code Composer Studio
Hi,
I am trying to implement a simple function to calculate seconds since epoch(1970-01-01 00:00:00) since MSP430F67xx MCU don't have counter mode in RTC modules. The following is the…
I am using Timer1 and Timer2 to capture edges on 4 hardware pins. These are working correctly.
The problem is that the Overflow Interrupt is starving "main.c". I never get back to main because I am constantly servicing the overflow.
How can I keep…
I currently am using the i2c module set up as an interrupt.
Is there available code that would show me how to set up the I2c for polling instead of interrupt driven? If so could you send this code to me.

Other Parts Discussed in Thread: MSP430F6721 The ACLK is being sourced from REFOCLK and under normal operating conditions, everything is working just fine. The MCLK / SMCLK are running at 8MHz and the 24bit AtoD is working well at 2MHz. The LCD is producing…
Part Number: MSP430F6721A Other Parts Discussed in Thread: MSP430F6721 Hi team,
My customer is developing a O2 detection product, and they want to use MSP430F6721 as the control unit for it's low power consumption and 24 bit delta-sigma ADC. Now, they…
Other Parts Discussed in Thread: MSP430F6721 I have seen in the forums that almost everybody uses an external IC like ADS124X or LMP90XXX to interface to the RTDs (using a constant current source passing through the RTD). I would like to use the SD24_B…
Other Parts Discussed in Thread: MSP430F6721 , MSP430F1121A I am using a MSP430F6721 for the first time and having problems with the UART (A0). I am using a 32KHz crystal on XT1. I look at the clock on PJ.3 and it is at 32KHz. I use ACLK for the baudrate…
Other Parts Discussed in Thread: MSP430F6721 Hi,
I'm using a MSP430F6721 during my reseach. Could anyone show me how to enter Low Power Mode 3.5 or 4.5?And how could I know whether if it enters? I have read the user guide for many times but still cannot…
I ALREADY CHANGED 2 CRYSTAL BUT PROBLEM IS THERE.
AND DEVICE IS MSP430F6721 REV A
AND IF THERE IS OSCILLATION BETWEEN 10HZ ABOVE, WHY ITS NOT SHOWING ON CRO SCREEN AND AT LEAST TIMER RESISTOR SHOULD INCREMENT???
Other Parts Discussed in Thread: MSP430F6721 Hi,
On MSP430F6721, I connect DVCC to one battery (2.7v), and connect AUXVCC1 to another battery(3v), I found ater switchover, AUXVCC1 is working power supply, it still ouput current from DVCC pin, which…
