Hi,
My name is Albert, now doing my project in my university. Currently doing the project of receiving and transmiting data from fpga to pc by using the hc11. In the project i need to
1 - get the data from pc through rs-232 port. The pc part is done by my team mate. She using the Visual Basic to transmit a set of data .
2 - the data then is receive by the hc11 and output the data to port B. The data need to be in 8 bits binary number.
3 - after the fpga process the data the hc11 need to get the data and then send back to the to the pc and the data from fpga also in 8 bits binary number.
Now i have the problem with this code can anyone help on this?
BAUD EQU $2B
SCCR1 EQU $2C
SCCR2 EQU $2D
SCDR EQU $2F
RDRF EQU $20
SCSR EQU $2E
PORTB EQU $04
ORG $00
ONSCI LDX #$1000
LDAA #$30
STAA BAUD,X
LDAA #$00
STAA SCCR1,X
LDAA #$0C
STAA SCCR2,X
SCIgetch LDX #$1000
BRCLR SCSR,X RDRF SCIgetch
LDAA SCDR,X
STAA PORTB,X
RTS
ORG $fffe ;define the reset vector to point to
FDB ONSCI ; the beginning of your code
**** there are few question i want to ask??
1. When i test this program using the simulator( THrsim11 ) i get the result what i get is in ASCII code. Is there anyway i can save the data in binary.
2. Then i try to download to the M68HC11 EVB, i cannot download to it because having error.
Because i need to get the data first so i need to get the reveiver code done before I can test the transmit and join it. I hope someone can help me...
Thanks for it...
