And what sort of display are you using?

UUmesh Lokhande Hi @abhishek_gangane. interesting project. I'd like to know if you're using APIs...

abhishek_gangane.•3/7/24, 8:54 AM

Yeah, currently I'm testing razorpay api for dynamic qrcode generation and giving feedback system to API via JSON

Ttechielew And what sort of display are you using?

abhishek_gangane.•3/7/24, 8:57 AM

I am on esp32 touch screen display using lvgl library but first wants to make work on websocket i.e., real time client and server response

techielewOP•3/7/24, 9:24 AM

nice there's plenty of esp32 exp here via @Umesh Lokhande @Aditya thakekar @youcef_ali @Joseph Ogbonna etc

Aditya thakekar•3/7/24, 9:26 AM

Great. You can. For display you can just you print statements. And work on webscokets. Later you can add all the displays

Wwafa_ath I am using Knowles SPH0641LU4H-1 🎤 and yes it is i2c

Yeah, this part looks good. It has PDM output as well. Check out this blog https://community.element14.com/challenges-projects/design-challenges/pathprogrammable3/b/blog/posts/p2p3-amd-vivado-cascaded-integrator-comb-cic-compiler-pdm-microphone-to-pcm-decimation

In my latest article, I discuss a particular aspect of designing the MQTT Topic Structure: Should we include an asset's Physical Location in the topic Structure?

What is your opinion?

Good day, who knows any LCD display vendor, that has small LCD around 20mm*20mm rounded shape. Or a rectangular shape around that size that uses I2C or SPI protocol. Need it in a design. @PCB & Analog @MCU, MPU & Firmware

Ok let me do that

Hii guys,
What is the best burner/programmer for the AVR microcontroller that is universal and can program most of the AVR chips?

Umesh Lokhande•3/7/24, 5:10 PM

I use AVR ISP MKII Programmer but if you want to save a few $ then the AVR ISP Programmer with USBasp firmware would also do the job.

Camila_99$$•3/7/24, 5:39 PM

Aah yes actually that’s what I’m looking for

Camila_99$$•3/7/24, 5:41 PM

@Umesh Lokhande Thanks for the quick response

CCamila_99$$Aah yes actually that’s what I’m looking for

Umesh Lokhande•3/7/24, 5:46 PM

Welcome! I've used both programmers with Windows and Ubuntu Linux with AVRDude both work like a charm

Considering the saying "jack of all trades, master of none".
What have you achieved mastery in?
If none yet, what would you want to become a Master of.

Flo•3/7/24, 11:21 PM

I like that question. I want to master the honesty towards myself. If we are talking technology it is ARM, U-Boot and Linux.

techielewOP•3/8/24, 2:08 AM

Nice question. I'd really like to master HDL

techielewOP•3/8/24, 2:09 AM

How about you?

Budweiser•3/8/24, 2:09 AM

I'd like to master rf circuit design, I have worked on the digital signal processing/software side of RF, but not done the hardware side

Budweiser•3/8/24, 2:10 AM

@techielew you ever heard of ModelSim?

techielewOP•3/8/24, 2:11 AM

Oh that's a good one. That's like a dark art only known to the Scandinavians lol

BBudweiser @techielew you ever heard of ModelSim?

techielewOP•3/8/24, 2:11 AM

I thought it sounded familiar and then looked it up and yes I have. Have you/do you use it?

Budweiser•3/8/24, 2:11 AM

when I worked in FPGA development I used it

Budweiser•3/8/24, 2:12 AM

I used VHDL, before doing anything further down the pipeline, I'd make it first work in ModelSim

Budweiser•3/8/24, 2:12 AM

if you want to e.g. learn VHDL, I extremely recommend using that, you can learn VHDL on that level much like you learn a software language

Budweiser•3/8/24, 2:12 AM

try out implementing basic digital circuits, simulate them, validate them..

Budweiser•3/8/24, 2:13 AM

you can also feed in data from files, and save output to files, so can already simulate signal processing stuff there

Budweiser•3/8/24, 2:14 AM

this is not going to get you all the way to making (functional/good) FPGA designs, but if you come from zero and have nobody else to guide you, then having all steps at once is a bit much, maybe do this, afaik ModelSim is free (at least it was some years ago)

Budweiser•3/8/24, 2:14 AM

so you can just download it, write your code, and simulate it

techielewOP•3/8/24, 2:14 AM

I was just looking for a free version

techielewOP•3/8/24, 2:14 AM

looks like it was when altera was still it's own version of altera

Budweiser•3/8/24, 2:14 AM

so just get an old version

Budweiser•3/8/24, 2:14 AM

for this purpose that won't matter

techielewOP•3/8/24, 2:14 AM

yeah i'm on the hunt

techielewOP•3/8/24, 2:15 AM

thanks for that tip. i'm in the process of slurping navadeep's brain but i'm sure he'll get tired of that soon haha.

Budweiser•3/8/24, 2:15 AM

it's just a way for you to get started very fast, and just get going with trying things out, also simulating VHDL by other people, on opencores or github

Budweiser•3/8/24, 2:15 AM

and alternating it

Budweiser•3/8/24, 2:15 AM

as a next step

Budweiser•3/8/24, 2:16 AM

I think that is a really neat way to pivot into digital design

Budweiser•3/8/24, 2:16 AM

also there should be a bunch of code examples in there already

techielewOP•3/8/24, 2:17 AM

Thank you! This looks fun

Budweiser•3/8/24, 2:17 AM

do that for some time, when you are confident with doing digital designs up to that level

And what sort of display are you using?
