8 bit shift register

Hi, I need some enlightment please. I've been reading about serial to parallel shift registers. But I'm having some trouble from theory to practice. In the Hello World example, how would one do an echo back after pressing enter? Given then rx_data is 8bits, I would store this in ram? and then when e...

Re: Question about Hello World serial demo

Hi blark,
tx_data and rx_data have 8 bits, I don't know if it is possible to send just one bit.
Check the LED + VB example here at the forum, that should help too.

FPGA MD5 Cracker

Hi all. Just found the following code to do a MD5 Cracker ( http://infinityexists.com/videos/fpga-md5-cracker/ ) What would be easier? Convert this to Verilog or mix both of them together? I mean, taking Mojo base project and instantiate the needed components from the code above ? We could loose the...

Re: Question about Hello World serial demo

Hi, I'm also a newbie, but I think that you can loose the rom code, and have something like this in pseudo-code: reg [7:0] temp; assign tx_data = temp; always @(posedge clk) begin new_tx_data = 1'b0; if (!tx_busy && button_pressed) begin new_tx_data = 1'b1; temp <= 8'b00110001 (binary for number 1) ...

Re: Mojo v3 - Shields

Hi,
My Mojo arrived today :) I'm already loading up some tutorials and examples, everything works fine :)
I understand the cost/features relation, but those new shields are very good news! In the mean time, I just ordered VGA and Audio Papilio Wings, sorry :| :|
Keep up the good work. Thanks.

Re: Mojo v3 - Shields

Hi there,
I'm thinking about making a simple VGA interface (schematics available online) for now, and maybe buy an Ethernet PHY later, when I learn more about it :)
Would you recommend any in particular?

Mojo v3 - Shields

Hi all, I've just bought, 5 minutes ago, Mojo v3 from an European website. This is my first time messing around with FPGA, although I have read and study a little before buying. Altera and Xilinx kits were my first choice as I didn't knew anything more. Then I was a little uncertain between Papilio ...
