| katharos | How do I multiplex a thing in migen? I need like... a clocked variable which switches between the 3 seven segment displays so I can show three different values | 06:42 |
|---|---|---|
| mithro | katharos: So a multiplexer is basically an if/case statement | 07:19 |
| katharos | ah right, I wasn't clear | 07:19 |
| katharos | I want it to continuously switch between 3 options - it's the clock part that I'm stuck on | 07:19 |
| katharos | I was going to use a 3 value array, but if-else would work too | 07:20 |
| mithro | katharos: So, you want a counter which increases every clock cycle | 07:21 |
| katharos | yep | 07:21 |
| mithro | katharos: Then you use that as a value in your if/case statement | 07:22 |
| katharos | yep... how do I create a counter that increases every clock cycle? | 07:22 |
| mithro | So, there are two types of statements types in migen/litex | 07:23 |
| mithro | "sync" and "comb" statements | 07:23 |
| katharos | So I need a Signal which I hook up to a clock in the comb statements? | 07:24 |
| katharos | oh right, I've been only work with the comb not the sync statements | 07:25 |

| katharos | aaah cool | 07:25 |
| katharos | So I need a value which increments by 1 every sync. Got it | 07:26 |
| mithro | katharos: Yeah | 07:27 |
| mithro | katharos: See the next slide | 07:28 |
| katharos | I did :) | 07:28 |
| katharos | Thanks! | 07:28 |
| mithro | katharos: If you get stuck, upload your code and I'll look at it | 07:35 |
| mithro | I will probably head to bed soonish | 07:41 |
| katharos | All good, I have to go in 30min anyway | 07:41 |
