[PIC C] Cosa Rara con Lcd_putc

[jdaniels]

Saludos, cuando escribo algo en la lcd, por ejemplo lcd_putc("todopic"); se escribe todo bien pero al final aparece un caracter raro, (todopic▓)no es el cursor pense que era el pero no,  ya que con la instruccion lcd_send_byte lo puse a que apareciera para ver si era este caracter y no lo es, sale justamente al final cuando escribo algo sea lo q sea, del resto el lcd ando fino no tiene rollos y la libreria es lcd.c a alguien le pasa lo mismo el caracter es como si fuera el FFh  o 255d es decir todo negro █ bueno en el lcd se ve asi ▓

Hola. ¿Parpadea ese caracter? Yo no me acuerdo si el cursor parpadeaba..creo que no. Debe ser el cursor. Fijate en la configuracion del LCD cuando lo inicializas, debes estar seteando que aparezca el cursor de ese modo.

Saludos

sip, ese cursor incluso puede parpadear y se configura al inicio del lcd.

[jdaniels]

Hola Bruno gracias por responder no parpardea, se mantiene fijo, si le doy para que aparezca aparece pero como debe osea sale "_", y sale asi todopic▓_ osea despues del caracter raro, que puede ser? suponte que sea el cursor como hago para que no aparezca osea se que debo cargar lcd_send_byte(0,0x0C) pero despues del lcd_init() o antes o como hago pa meterlo en la libreria

Si subes el codigo del programa y la libreria podremos ayudarte mejor.
Pegalo utilizando el boton Codigo y selecciona CCS..

[code=css][code]
#include <16F877A.h>
#fuses HS,NOPUT,NOPROTECT,NOBROWNOUT,NOLVP,NOWDT  // Fusibles a Configurar
#use delay(clock=20000000)                                                 // Cristal
#include <LCD2.c>                                                               // Libreria Pantalla LCD
 
void main()
{
lcd_init();
lcd_putc("Hola");
}

Tan simple como eso ojo lcd2 es lo mismo que lcd.c solo modificando el delay_cycles() por delay_us()[/code][/code]

[jdaniels]

Ok les tengo algunos avances si pongo lcd_putc('A'); osea un solo caracter no aparece el dichoso caracter raro, pero si tengo que escribir una palabra entiendase lcd_putc("lo que sea"); si aparece, con printf no sale el caracter raro, escriba una letra o una palabra no sale con printf, que sera? puede que sea una locura toda rara de ccs o quien sabe, pero alguien podria probar a ver si tambien le pasa lo mismo o el loco aqui soy yo?

PD: Uso ccs version 4.013

Creo que deberias utilizar la ultima revision de la version 3, creo que es la 3.249, verificalo...

[vszener]

Es que antes cosas raras, es mejor ver el listado de bugs 


Suerte!!!

[jdaniels]

Ok gracias MGLSOFT y vszener por cierto la version la puse en mi ultimo comentario, estan leyendo de volada??

Casualmente tengo esa version (3.249) déjame instalarla y les aviso que tal

[jdaniels]

Buenos muchachos les comento los resultados

Despues de instalar la version 3.249 (parece windows 95 jaja) y lidiar un buen rato con ella, me he dado cuenta que no muestra el display a 20Mhz, le puse la libreria LCD.C modificada para >4Mhz pero nada, en fin el asunto es que cambie a 4Mhz y FUNCIONO, no me sale el caracter loco ese, ya sea que ponga lcd_putc para escribir una palabra o letra lo hace de maravilla. Entonces me puse a pensar y si tambien "camino" hacia adelante? y instale la version 4.038 y tambien funciono calidad no sale el dichoso caracter, y nuevamente me puse a revisar lo que pego MGLSOFT y creo que el error deja de estar en las versiones 4.020 porque me parece que es este (4.020  The cursor disapearing on blank lines in the IDE is fixed) ahora a partir de que version saldra ni idea no me pondre a averiguar eso jaja

Gracias nuevamente a todos por la ayuda prestada, fue de gran pero gran ayuda
