Am trying to read a received msg from Port C and forward it to port B, it doesn’t work.
When I debugged the code, I found out that the code execution stops in the read function and goes back to the beginning of the loop but it doesnt proceed after
wfd n = cof_serCread(msgData, strlen(msgData), 20);
Am I reading the array in a wrong way? Or maybe my timing is wrong? I tried to change the function parameters but with no use.
Your help is highly appreciated.
void main(){
int n;
static const char msgData[]= {"Hiiii am in serial c"};
brdInit();
serCopen(115200);
serBopen(115200);
loopinit();
while (1) {
loophead();
costate {
wfd n = cof_serCread(msgData, strlen(msgData), 20);
wfd cof_serBwrite(msgData, n);
}
}
serCclose();
serBclose();
}
Hello,
cof_serCread function reads specified number of bytes from serial port and stored it in a buffer.
Here there is no data available to read in serial port. So control goes back.
If you want to put some message buffer into serial port u can directly use command serXputs/write(see in help). After putting this data into serial port u can use read function to read data from serial port. ( read function/gets function to read serial data)

Thank you for your reply, i tried your suggestion but still it gives me the same problem i faced earlier. Am not sure if the serXputs works properly in my code!
Anyways, I removed all the cofunctions because i would like to get a better understanding of sending and recieving msgs to ports.
However, I still have a problem! I created a buffer that i store in it my msgData and pass it to port C then B. I get an empty buffer in port B which am sure that i dont pass an empty array.
Am new to embedded systems development, and your help is highly appreciated.
Please, do have look to the code.
while (1)
{
loophead();
costate
{
memcpy(buffer, msgData, msgData(string2));
serCputs(buffer);
memset(buffer, 0x00, sizeof(buffer));
// n is 0 when i run the code
n = serBread(buffer, sizeof(buffer),20);
serBputs(buffer);
printf("%s", buffer);
}
}
