Hello everyone,
I am sending this string over serial, using KEIL ARM Uvision demo version :
"0x86 0x21 0x09 0x00 0x8D 0x0A 0x00 0x61 0x58"
And, when sending 0x0A, receive the corresponding ASCII character plus a 0x0D (enter). I do not want that enter !! I made my own putchar function, as seen on other posts, but it doesnÂ't work at all. Does anyone suffered the same problem ? Thanks in advance. Gabriel.-
Look at your function which sends character to the serial port.
When for example printf, putc are used then retargeting of the fputc function is required which usually calls a function named sendchar. The adding of 0x0D after 0x0A is usually implemented in this function.
Example for LPC2xxx:
#define CR 0x0D int sendchar (int ch) { /* Write character to Serial Port */ if (ch == '\n') { while (!(U1LSR & 0x20)); U1THR = CR; /* output CR */ } while (!(U1LSR & 0x20)); return (U1THR = ch); }
You just need to get rid of the if statement in the above example.
