Hi all,
I am new to this series of controller but earlier i had worked with
PIC24FJ256GB406.
In PIC24FJ256GB406 controller(see datasheet at
http://www.kynix.com/Parts/158737/PIC24FJ256GB406-I%2FPT.html), any
remappable pin can be configured for any type of peripheral feature for
example we can map uart3RX on any of the remappable pin. There is no
restriction to which remappable pin uart3rx has been connected. Based on
this only i had designed my new design for PIC18F66J94 controller and
got PCB fabricated also but i think i have done blunder in configuring
the remappable pins.
For PIC18F66J94 controller, remappable pins have been grouped together
and divided into different groups i.e. for using U3RX any one of these
remappable pins can only be used i.e.
RP0,RP4,RP8,RP12,RP16,RP20RP24,RP28,RP32,RP36,RP40 and RP44.
I didn't care for this grouping while designing the schematic.
Now i need to configure 3 uart lines through remappable pins as follows
RP3->RX,RP2->TX,RP1->RX,RP0->TX,RP18->TX,RP19->RX. I can't change the RX
and TX lines on the slave device as they are non-remappable.
Out of these 3 i can configure only one set of uart line i.e. RP3 as
U1RX and RP2 as U1TX. I want to know if there is any other possibility
without changing the hardware connection?
Regards
