Defined string with 4 characters is sizeof 4 in watch and 5 in compiled code.

So, just out of curiosity, how can sizeof(LOGGER_SERIAL_DEFAULT) be both 4 (in the QuckWatch) and 5 in the compiled code (red line in disassembly) ? It's defined as: #define LOGGER_SERIAL_DEFAULT "----" So in my mind it should be 4 (if the compiler wanted to count the quotes it would be 6) but NEVER 5. http://e2e.ti.com/cfs-file.ashx/__key/communityserver-discussions-components-fi...

Timer A jitter on G2 LaunchPad

What sort of jitter should I see using ACLK on timer A w/ the 32 KHz xtal in place? I'm seeing ~1.5 us on the falling edge of a nominally 30.5 us pulse. I'm generating a pulse train using timer A in up mode driving LED2. I expect to see jitter in the pulse length using SMCLK derived from the DCO at the 8 MHz calibrated frequency, but I also see it if I change to ACLK for timer A (still DCO fo...

If I multiplex the display and key...

Hi folks, Some of you may remember awhile back I posted about a weird problem where adding more code or functions to the project caused functional code in other parts to fail while executing seemingly simple intrinsic functions like atof(), sprintf(), or even __delay_cycles(). I now see that I left the segment from 0x30000 + sizeof(sysConfigurationType) to end of segment unprotected and b...
