That's a good idea. I had been thinking that such things would just go in the #dev-heads-feed or similar. Maybe the Events tab, though that might get confusing.

Perhaps we create a "resources" channel... What says the group?

techielew•2/16/24, 1:39 AM

Hey guys :waving_hand:
A little over 12 hours 'til our next meetup and we have a topic this week I think everyone will enjoy: "Who is Your Engineering Hero? Identifying, Engaging & Maximizing Technology Mentors"

We hope you'll join us and share. Here's the meeting thread in case you want to drop some thoughts in before, after, or if you can't make it: https://discord.com/channels/1130679493799977062/1207862407028932659

See you tomorrow (or today for some of you)!

JJoseph Ogbonna Yes, you mean battery power/low powered Chips

pallavaggarwal•2/16/24, 2:07 AM

Yes

Ppallavaggarwal Yes

Joseph Ogbonna•2/16/24, 2:09 AM

I am

pallavaggarwal•2/16/24, 2:10 AM

Great. Do you mind sharing details?

Saßì•2/16/24, 2:24 AM

@Amin Sujan Welcome,! We're happy to have you as a DevHead. Feel free to let us know what you're working on now and a bit about your technical background.

Ppallavaggarwal Anyone who is building something low power?

onky•2/16/24, 5:43 AM

I am working on one project.

Ppallavaggarwal Great. Do you mind sharing details?

Hi @pallavaggarwal Just for fun I built a battery-operated handheld calculator around 8-bit ATmega328 MCU. Here is a live demo: https://www.facebook.com/reel/259501753618035

just saw the video

pallavaggarwal•2/16/24, 10:31 AM

did u end up making the finished version?

Umesh Lokhande•2/16/24, 10:39 AM

you mean on actual PCB? I have to find time this summer to convert this working circuit from the Protoboard to the real PCB with casing. but I enjoyed this weekend project

pallavaggarwal•2/16/24, 10:42 AM

yes, actual PCB version

pallavaggarwal•2/16/24, 10:43 AM

it would be great make that func project with latest CH32V003

Ppallavaggarwal it would be great make that func project with latest CH32V003 🙂

Umesh Lokhande•2/16/24, 10:50 AM

Sure, it can be done with CH32V003. All you need is plenty of GPIO Pins for buttons and I2C Pins for OLED Display that's all. Firmware is also very simple. I'll drop the circuit & code later today in case you wish to review. I skipped some capacitors in my case to avoid hand solder.

pallavaggarwal•2/16/24, 10:53 AM

Yeah sure. I like you being lazy and leaving poor caps home

We'll be starting this week's Office Hours in about 45 minutes. See the link to join above or in the "Events" tab on the left menu. Come ready to share about your technology mentor!

See you soon!

Hey guys (especially @MCU, MPU & Kits devs), we just launched a new #polls to see what MCU architecture everyone is designing on (or would prefer to be designing on). Check it out: https://discord.com/channels/1130679493799977062/1199293807737450538/1208322777757519952

Missing MSP430

Oonky Missing MSP430 😅

techielew•2/17/24, 8:07 AM

If I added it would you vote for it lol?

onky•2/17/24, 8:08 AM

Yes, I am working on one. Low power device.

onky•2/17/24, 8:09 AM

STM has killed most of the competition. Firmware libs from TI is painful compared to ST

Oonky Yes, I am working on one. Low power device.

techielew•2/17/24, 8:11 AM

* First, let @pallavaggarwal know what you're working on. He was curious about low-power device designs in server.

* Second, I just added a comment on the poll to reply with any device/architecture that's missing. We should track this over time.

* Yes. Everything but ESP and AVR and RP2040 (curious if anyone will comment that last one out :))

techielew•2/17/24, 8:15 AM

I lied. I actually want to know what your low-power device design is too, @onky lol. And why is it on MSP430?

onky•2/17/24, 8:19 AM

I am working on loop powered instrument, max current consumption for the whole circuit must be less than 4mA. The customer is old school has trust in MSP430 and wants me to use the same.

Umesh Lokhande•2/17/24, 11:25 AM

Hi, @wafa_athmani , Publisher, and Subscriber both can send and receive data i.e. payload back and forth. This can be managed by the MQTT Broker so we as a client have to do nothing apart from publishing the message and subscribing to the topic.

Yes but can one be publisher and also subscriber to the same topic ! For example receive the message or the notification from publisher and then after became a publisher ( to the same topic)
