RS232 in C folosibil pe PIC12F675

[lama]

Are cineva (de dat) codul C ptr picc ptr comunicare seriala?Multumesc

Coduri pentru uart sunt cu miile .

Depinde de compilatorul pe care-l folosesti.

Si daca-ti da cineva un cod, ce faci cu el.

Tu trebuie sa faci comunicatia in functie de parametrii tai , nu?

Examples: byte  x,y,z;printf("HiThere");printf("RTCCValue=>%2x\n\r",get_rtcc());printf("%2u %X %4X\n\r",x,y,z);printf(LCD_PUTC, "n=%u",n);

Si tipurile de format

Format:The format takes the generic form %nt. n is optional and may be 1-9 to specify how many characters are to be outputted, or 01-09 to indicate leading zeros, or 1.1 to 9.9 for floating point and %w output. t is the type and may be one of the following:c Character s String or character u Unsigned int d Signed int Lu Long unsigned int Ld Long signed int x Hex int (lower case) X Hex int (upper case) Lx Hex long int (lower case) LX Hex long int (upper case) f Float with truncated decimal g Float with rounded decimal e Float in exponential format w Unsigned int with decimal place inserted. Specify two numbers for n. The first is a total field width. The second is the desired number of decimal places.  Example formats:Specifier Value=0x12 Value=0xfe %03u 018 254 %u 18 254 %2u 18 * %5 18 254 %d 18 -2 %x 12 fe %X 12 FE %4X 0012 00FE %3.1w 1.8 25.4  * Result is undefined - Assume garbage.

Necesita

#pin_select U1RX=PIN_B12 // doar pentru test#pin_select U1TX=PIN_B14 // doar pentru test//#use rs232(UART1,baud=19200,parity=N,bits=8,stream=com_1)// or#use rs232(UART1,baud=115200,parity=N,bits=8)

Asta pentru CCS compiler.

Pentru C18, C30, Hitech

void InitUART1(void){	//unsigned char c;	U1MODEbits.UARTEN	=1; 		// UART pins controlled by UART	U1MODEbits.USIDL	=0;			// UART communication continue in Idle Mode	U1MODEbits.ALTIO	=1;			//UART using alternate pins	U1MODEbits.WAKE		=1;			// Wake up enable in sleep Mode	U1MODEbits.LPBACK	=0;			// Loopback mode disabled	U1MODEbits.ABAUD	=0;			//Autobaud process disabled 	U1MODEbits.PDSEL	=0;			// 8-bit data,  no parity	U1MODEbits.STSEL	=0;			// 1 stop-bit.	U1STAbits.UTXISEL	=0;			//Transmission Interrupt Mode Selection bit	U1STAbits.UTXBRK	=0;			//UxTX pin operates normally	U1STAbits.UTXEN		=1;			// Transmit enable	U1STAbits.URXISEL	=0;			// Interrupt occurs when one charater is received	U1STAbits.ADDEN		=0;			// Address detect disabled	U1BRG=31;						// Value for 57600 bps baudrate	//U1BRG=15;						// Value for 115200 bps baudrate	ConfigIntUART1(UART_RX_INT_EN & UART_RX_INT_PR4 & UART_TX_INT_DIS & UART_TX_INT_PR0);	}

printf("abc %i\n", (signed int)100 );

Vino cu mai multe detalii, nu are sens ceea ce ceri

Pentru wangine: cred ca nu te-ai uitat bine mai sus. Scrie clar picc. Ca librarii gata gasesc in CCS sau MikroC. Iar ce gasesti pe net este in general in asm.

Vezi in directorul samples->serial->bitbang de la picc (in linux e in ...picc9.80a/samples/serial/bitbang), poate-l poti adapta la picul tau.

Ma uit. Multumesc

CCS si HiTech au aceiasi denumire la compilator: picc.exe. Pentru a evita confuzia pe viitor specifica numele compilatorului ( Hitech, C18, SDCC, CC5x, CCS, etc) ca am avut si eu probleme cu numele asta identic de "picc".

Imi cer scuze. Nu am instalat decit doua compilatoare.
