[C2k Piccolo Launchpad jumpers JP4-JP11]

hello

 

what is the purpose of jumpers JP4-JP11?

 

I guess it allows to select on which pin-array (J2 or J6) one will use GPIO16/17/32/33.

It could be done by cutting the proper route, and pads allow to re-solder it (?).

If so, do I need to do this if I use GPIO16/32 and 17/33 exclusively?

[sizeof not working?]

Hello,

 

I tried

 

 

void sizes()
{
char buff[256];

sprintf(buff,"sizeof(char)=%d\n",sizeof(char));
SCI_putStr(mySci,buff);

sprintf(buff,"sizeof(short int)=%d\n",sizeof(short int));
SCI_putStr(mySci,buff);

sprintf(buff,"sizeof(int)=%d\n",sizeof(int));
SCI_putStr(mySci,buff);

sprintf(buff,"sizeof(long int)=%d\n",sizeof(long int));
SCI_putStr(mySci,buff);

sprintf(buff,"sizeof(long long int)=%d\n",sizeof(long long int));
SCI_putStr(mySci,buff);

sprintf(buff,"sizeof(float)=%d\n",sizeof(float));
SCI_putStr(mySci,buff);

sprintf(buff,"sizeof(double)=%d\n",sizeof(double));
SCI_putStr(mySci,buff);
}

 

On my serial terminal I see

 

sizeof(char)=0

sizeof(short int)=0

sizeof(int)=0

sizeof(long int)=0

sizeof(long long int)=0

sizeof(float)=0

sizeof(double)=0

 

what can be wrong?

[C2k Piccolo Launchpad bugs + workarounds]

hello,

 

here are some bugs I have noticed.

 

1) controlSUITE/development_kits/C2000_LaunchPad/f2802x_examples/C2kLaunchPadDemo, project settings.

Some project paths are invalid for case-sensitive operating systems.

There is:

.../F2802x_common/...

There should be:

.../f2802x_common/...

 

2) controlSUITE/development_kits/C2000_LaunchPad/f2802x_common/cmd/F28027.cmd, line 117.

Linker command file typo.

There is:

   .text			   : >> FLASHA | FLASHC | FLASHD.	   PAGE = 0

There should be:

   .text			   : >> FLASHA | FLASHC | FLASHD,	   PAGE = 0

 

3) ~/controlSUITE/development_kits/C2000_LaunchPad/f2802x_common/source/spi.c. line 563.

Register name typo prevents from configuring FIFO interrupt level for SCI/Rx.

There is:

    spi->SPIFFTX &= (~SPI_SPIFFRX_IL_BITS);

There should be:

	spi->SPIFFRX &= (~SPI_SPIFFRX_IL_BITS);
