Serial com PIC <> PC - what is best?

[flotulopex]

I'll try with a 4MHz crystal.

At the end, I want to send WORDs to the PIC's program memory. I tried this internally with WRITECODE and it works as long as 4 WORDs are stored in a row.

I can't figure out how to send more than 1 data from the terminal to the PIC. So now, I have to press "Send" a couple of times until the LCD shows up some results. I send the datas comma separated, it this so?

Since I'm testing step-by-step, I didn't made an endless loop.

Here is the SERIN version:

@ DEVICE PIC16F88,INTRC_OSC_NOCLKOUT,PROTECT_OFF,WDT_ON,PWRT_ON,MCLR_ON
@ DEVICE PIC16F88,BOD_ON,LVP_OFF,CPD_OFF,DEBUG_OFF,CCPMX_OFF

' Register settings
OSCCON = %01100000  'Internal RC set to 4MHZ
ANSEL  = %00000000  'Disable Analogue Inputs

' LCDOUT command (if defaults are not changed, DEFINEs can be omitted)
DEFINE LCD_DREG PORTB       'LCD data port 
DEFINE LCD_DBIT 0           'LCD data starting bit 0 or 4 on µC 
DEFINE LCD_RSREG PORTA      'LCD register select port 
DEFINE LCD_RSBIT 3          'LCD register select bit 
DEFINE LCD_EREG PORTA       'LCD enable port 
DEFINE LCD_EBIT 2           'LCD enable bit 
DEFINE LCD_BITS 4           'LCD bus size 4 or 8 
DEFINE LCD_LINES 2          'Number lines on LCD 
DEFINE LCD_COMMANDUS 2000   'Command delay time in us 
DEFINE LCD_DATAUS 50        'Data delay time in us

This is the HSERIN version, same problem as before:

TXSTA  = %00100000  'Enable Transmit Bit
SPBRG  = 6          'Set baudrate to 9600

DEFINE LCD_DREG PORTA       'LCD data port
