Posted on September 27, 2017 at 19:17Hello,
I am writing a test program on my board (xpc56xx evb motherboard) and I want to receive on my terminal throught the UART numbers and text strings.
When I get the data on my serial terminal (RealTerm) I receive properly the strings ('Test program start') but not the variables' value (pcval1,pcval2,pcval3). (see screenshot).
This is my code:
#include 'components.h'
uint32_t volatile *pcval;
uint32_t volatile cval;
uint32_t volatile *pointer1;
uint32_t volatile *pw;
uint32_t volatile w = 0x000FFF;
uint32_t volatile giri1,giri2,giri3;
/*
* Application entry point.
*/
int main(void) {
/* Initialization of all the imported components in the order specified in
the application wizard. The function is generated automatically.*/
componentsInit();
giri1=0x00000001;
giri2=0x00000002;
giri3=0x00000003;
/*
* Activates the serial driver 1 using the driver default configuration.
*/
sdStart(&SD1, NULL);
/* Application main loop.*/
while (1) {
unsigned i;
osalThreadSleepMilliseconds(100);
osalThreadSleepMilliseconds(100);
osalThreadSleepMilliseconds(100);
osalThreadSleepMilliseconds(100);
chnWriteTimeout(&SD1, (uint8_t *)'Test program start\r\n', 20, TIME_INFINITE);
chnWriteTimeout(&SD1, (uint8_t *)'Test program start\r\n', 20, TIME_INFINITE);
giri1=giri1+1;
pcval=&giri1;
chnWriteTimeout(&SD1, (uint8_t *)pcval,4,TIME_INFINITE);
giri2=giri2+1;
pcval=&giri2;
chnWriteTimeout(&SD1, (uint8_t *)pcval,4,TIME_INFINITE);
giri3=giri3+1;
pcval=&giri3;
chnWriteTimeout(&SD1, (uint8_t *)pcval,4,TIME_INFINITE);
chnWriteTimeout(&SD1, (uint8_t *)'\r\n',2,TIME_INFINITE);
}
}
is there a strategy with I can read proper values?
Thank you in advance!
Fabio
