 Forum: General CCS C Discussion Posted: Fri Apr 22, 2005 6:54 pm Subject: Changing baud rates, parity, etc. at run time? |
| Are you using the Hardware or Software UART?
set_uart_speed(9600); and set_uart_speed(300); would change your baud rates, but would not change your parity. The #use RS232 statements actually do ... |

| I would guess not. I received the following from CCS Support.
"The problem has been confirmed. We evaluate the right side of the = before the left side even though you have ( ) on the left side. ... |

Forum: General CCS C Discussion Posted: Wed Mar 02, 2005 12:33 pm Subject: RS232_erros |
| From the #USE RS232 in the help file....
The definition of the RS232_ERRORS is as follows: No UART: � Bit 7 is 9th bit for 9 bit data mode (get and put). � Bit 6 set to one indicates a put ... |

| The set_uart_speed only helps for baud rate, not parity.
Looking at my listing for the multiple #use RS232 shows no code generated other then the one RS232 stub at the beginning of the listing. ... |

| Thanks for the info. I did not see the SET_UART_SPEED() functon before.
I knew you could use multiple #use RS232 statements to use more then one serial port, but when I attempt to use multiple #us ... |

| #use rs232(baud= 38400,xmit=PIN_C6,rcv=PIN_C7, errors)
This allows a single set of communication parameters to be configured. My problem is that our project uses dip switchs to select the communica ... |

Forum: General CCS C Discussion Posted: Mon Feb 28, 2005 12:10 pm Subject: PCH problem with *ptr++ = '0' + (*ptr); |
| PCH seems to have a hard time with expressions that reference a pointer, assign to the same pointer and increment the pointer.
*ptr++ = '0' + (*ptr); While this does increment ptr correctly, it s ... |
