Forum Post: RE: MSP430FR5969 hardware problem at 16MHz
Olli, I'm not understanding your clocking situation here. First you set the DCO to 1MHz then do MCLCK/2 and SMCLK/32. Then you do the 16MHz workaround and come out as MCLCK=16MHz/2 and SMCLK=16MHz/32....

Hi Jerry, I did a little more digging and found this E2E post discussing a similar topic: Differences between "msp430.h" and "io430.h" The discussion about accessing individual I/O bits starts about...

Please Help- This is getting frustrating!! I put the following test code sequence in CCS C; P8SEL = 0x00; // all pins of PORT8 are DIOs P8DIR = 0xFF; // // i/o all out P8OUT = 0xFF; P9SEL = 0x00; //...

I just got this to work!!! I had the compiler project set to "Release" Mode. When I switch to "Debug " Mode it single stepped correctly and changed the port bits as expected. I need to generate an...

I think you can do this (but didn't try it myself): #define B8_0(x) (((volatile struct bits8 *) (x)) ->b0) #define B8_1(x) (((volatile struct bits8 *) (x)) ->b1) #define B8_2(x) (((volatile...

Thanks Brian, What you say makes sense, that the compiler would ignore the 2nd,3d statements(96,97) accept that the P8 bit 1 came in as a 1 and was never changed to 0 by line 95! I'I will add the...

It will crash if I do that. That back an forth was reached by trial and error which allowed this simple test program to run. Hence the comment in OP that moving the clock change to the init() routine...

A hardware serial port is implemented on the MCU chip itself. A software serial port is created with user written code that manipulates standard I/O pins to create the serial port.

Somehow I actually solved this. Go to Project-->Options and then in "Debugger" category change "Run to" field from "Main" to "exit". Your code will begin executing immediately when you download. So...

Praveen, You have setup the ADC to do multiple conversions continuously. The toggle conversion is only needed once to start the mode. I am concerned that the corruption may be related to the changing...

Olli, I'm able to reproduce your issue reliably and have narrowed down the issue to the CS_initClockSignal(). Strangely, if you step through the function its ok, but trying to run even at debug speed...

Hi Mitchell, Thanks, I am not connecting anything to AVCC and DVCC. Yes I am providing separate 10k pull-up going from P2.0 and P2.1 to the 3V battery. Thanks, Mukesh

No, I don't want higher baud rate, 9600bps is okay for me.

No, this is hardwired inside the chip. Dennis
