Hi,
I have installed
SmartSnippets Studio v.16.3.918
and
SDK (DA1468x_DA15xxx_SDK_1.0.14.1081.zip)
(but not the patch to the SDK)
and run the example described in
User Manual
DA1468x Getting Started with the
Development Kit
UM-B-047
Everything works as detailed in the PDF document
BUT
although printf() works well, getchar() does no work
In the filemain.cin the template in the function
static void system_init( void *pvParameters )
Add after the line
#if defined CONFIG_RETARGET
retarget_init();
#endif
the lines:
printf ("\n>> %s %s %d\n", __FILE__, __FUNCTION__, __LINE__); fflush(stdout);
字符c =获取字符();
printf (" % x % d % c \ n”,c,c,c);fflush(stdout);
The second printf() never happens
I have uploaded the C file in this forum topic by changing its file extenstion from C to PDF (only way to upload)
Your insights are most appriciated.
Best,
Rami
Hi ramig972,
Could you please run it in debug mode and check where it gets stuck? Please share a screenshot..
Unfortunately I am not able to open the attached file. Would it be possible to zip it and attach it again?
Thanks, PM_Dialog
in the file main.c
function system_init()
添加boldlines :
#if defined CONFIG_RETARGET
retarget_init();
#endif
printf ("\n>> %s %s %d\n", __FILE__, __FUNCTION__, __LINE__); fflush(stdout);
字符c =获取字符();
printf (" % x % d % c \ n”,c,c,c);fflush(stdout);
please share if you see the second printf() statement of the exection steps
Hi ramig972,
You should not call this code snippet in system_init() as it will delay the system initialization. Please try to execute it in prvTemplateTask. Probably you might need increase the heap size.
Thanks, PM_Dialog
That was the original code, .
I tried again increading the stack size and moving:
/* Start main task here (text menu available via UART1 to control application) */
OS_TASK_CREATE( "Template", /* The text name assigned to the task, for
debug only; not used by the kernel. */
prvTemplateTask, /* The function that implements the task. */
NULL, /* The parameter passed to the task. */
2048,
// 200 * OS_STACK_WORD_SIZE, /* The number of bytes to allocate to the stack of the task. */
mainTEMPLATE_TASK_PRIORITY, /* The priority assigned to the task. */
task_h ); /* The task handle */
OS_ASSERT(task_h);
and
/
static void prvTemplateTask( void *pvParameters )
{
OS_TICK_TIME xNextWakeTime;
static uint32_t test_counter=0;
/* Initialise xNextWakeTime - this only needs to be done once. */
xNextWakeTime = OS_GET_TICK_COUNT();
for( ;; ) {
////////////////////////////////////////////////////////////////
printf ("\n\n>>>%s %s %d\n", __FILE__, __FUNCTION__, __LINE__);
fflush(stdout);
// Read the next character from the keyboard.
char c = getchar ();
fflush(stdin);
printf (">>>%s %s %d\n", __FILE__, __FUNCTION__, __LINE__);
fflush(stdout);
if (isprint((int)c)) {
printf (">>> %c %d %x\n", c,c,c);
} else {
printf (">>> %d %x\n", c,c);
}
fflush(stdout);
//////////////////////////////////////////////////////////////////
Still does not work. only
Getting single printout and the blinky test does not work:
>>>../main.c prvTemplateTask 141
Hi ramig972
Could you please change the value of the __HEAP_SIZE in the bsp_defaults.h?
Thanks, PM_Dialog
