SJA1000 documentation helps a lot. Page 61 shows steps to write a register (see lower part) following those steps, some registers must be configured. 0) at the beginning, IP is in reset_mode. 1) set register 31 to define basicCAN or peliCAN 2) bus timing registers (6 and 7) if peliCAN 3) acceptance codes and masks (16 to 23) if peliCAN 4) leave reset_mode: register 0, with value 0 5) set register 16 to 28 with frame format (11/29 bit id) , remote_transfer/dataframe, data byte lenght with register(16), MSG id, and message data 6) now IP core is ready to send. Set register 1 with value 1 (TX_data) My problem is that i can't make it work in an implemented design. I can't even change the first register. I go to a state machine controlled by a pushbutton (this code is executed everytime button is pushed, incrementing int_cnt) case (int_cnt) 4'd1: ale_i = 1'b1; 4'd2: data_to_port = rd_i ? 8'bz : 8'd31; 4'd3: ale_i = 1'b0; 4'd4: cs_can_i = 1'b1; 4'd5: data_to_port = rd_i ? 8'bz : 8'b11000100; 4'd6: wr_i = 1'b1; 4'd7: wr_i = 1'b0; 4'd8: begin cs_can_i = 1'b0; NewStep = 1'b1; end endcase I have connected clkout_o to a pin to check freq with an oscilloscope, but it is changing 2*tclk, default value. So it is not changed actually. Please, can anyone help me set register's value? Thanks in advance Aitortxo.   by chandravincent@g... on 15-Sep-2008 Hai ,,,,,, could u provide me some assistance in the Implementation of the CAN controller, I require an internal block diagram for each block shown in the figure in this site. Could you help me somehow, Also i require some assistance regarding the Hardware implementation of the CAN controller Plz reply soon, Thanks in advance.plz send me the details to chandravincent@gmail.com   by mdnaimaths@y... on 01-Apr-2007 I do need the VHDL code for CAN controller . from where can i get it??? I need it urgently.... Thanks in advance.   by mdnaimaths@y... on 01-Apr-2007 I do need the VHDL code for CAN controller . from where can i get it??? I need it urgently....
