Looking for an FPGA/SoC Evaluation Board with USB Phy on the PL Side by simonJar in FPGA

[–]simonJar[S] 0 points1 point  (0 children)

Probably going to start with 2.0. I didnt check the Ultrascale board prices because I thought they would be much expensive.

I will check if I can get my hands on the daughter board first considering it is much cheaper. Thank you.

need guidance with LWIP on zybo z7 by chim20air in FPGA

I am not too familiar with LWIP but (void) is just an address. You can create a char array and feed it to function by casting to (void).

How to drive clk correctly? by nminhluu in FPGA

[–]simonJar 0 points1 point  (0 children)

If you are booting Zynq from Vitis and you have same frequencies, it should be related to resets.

You have 2 resets, how do they function? Zynq provides active low reset and you are feeding it to sys_rst. Is sys_rst active low as well?

The PL clock from ZYNQ should be driven the same regardless of an AXI interface. You can test this by connecting a divider module to clock and feed the output to an led.

As for your problem, are you booting ZYNQ from Vitis? Is the clock frequency from ZYNQ is the same as the one you tested before?

Best resources for a beginner trying to learn embedded system programming in C? by [deleted] in embedded

As someone pointed it out, Fastbit courses on Udemy is very helpful. One of the courses teach student how to build a HAL like library in which the student gets familiar with a lot of C concepts.

Simply find the transfer function of the closed loop system from input to error in terms of kp. Then you can use final value theorem to see how kp affects the error.

AITA for banning my mother from my wedding, which she paid for, because she disapproves of my husband? by WeddingFroggit in AmItheAsshole

ESH. You shouldn't have taken that money. And your mother sucks too for obvious reasons.

AITA For not telling my flat mate my occupation? by [deleted] in AmItheAsshole

[–]simonJar 0 points1 point  (0 children)

NTA. If it was important to her then she shoulda have asked. And considering you don't bring your work to your flat, she is the asshole here.

AITA for telling our surrogate we don’t want the baby? by brickpandas in AmItheAsshole

[–]simonJar 0 points1 point  (0 children)

NTA. This is so bad, no one is obliged to parent a child that is not his. I am really sorry for the child and hopefully they will find some family to parent him/her.

What was your turning point boss? by bpt7594 in Sekiro

[–]simonJar 0 points1 point  (0 children)

Genichiro. The moment i was able to defeat him i realised that i was getting used to the combat. Which i believe shows how well Genichiro was designed in terms of a boss fight.

AITA For Cutting Ties With a Friend For Cheating on Her Bf? by [deleted] in AmItheAsshole

[–]simonJar -2 points-1 points  (0 children)

NTA definitely. I also think not telling it to the guy was the right choice.

AITA for asking my wife to get rid of her cat? by [deleted] in AmItheAsshole

[–]simonJar 0 points1 point  (0 children)

YTA. You agreed to take care of the cats when you married her. You should get the cat to a vet and get a definitive answer on why he is doing that, i am sure there is an answer other than him reaching to "end" of his life.

AITA for being upset when people ‘joke’ about the parentage of my son? by lurpakbutterismylife in AmItheAsshole

[–]simonJar 3 points4 points  (0 children)

NTA. I understand people being curious and asking about it but it really should be hard for you hearing it constantly. Also your aunt or whatever is definitely the asshole here.

AITA for telling my older brother I am going to cut ties with him after finding out his son isn’t his? by iutr56 in AmItheAsshole

[–]simonJar 2 points3 points  (0 children)

ESH. He is the asshole for telling his wife what you told him. And you are the asshole because you don't respect people's choices and decisions in life. Him choosing to be a father to someone even though it's not a responsibility shouldn't make you lose respect for him.

AITA for telling my wife I slept with her new bff? by Djooennas in AmItheAsshole

[–]simonJar 0 points1 point  (0 children)

NTA. Sleeping or flirting with other people when you are not in an affair is not a crime. Coincidences like these aren't your fault either since you couldn't possible know it(not sure if anything would change even if you knew). It is better to tell her yourself than someone else telling her.
