did u end up making the finished version?

Ppallavaggarwal did u end up making the finished version?

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

pallavaggarwalOP•2/16/24, 10:42 AM

yes, actual PCB version

pallavaggarwalOP•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.

pallavaggarwalOP•2/16/24, 10:53 AM

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

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)

You can both subscribe and publish to the same MQTT topic, but that is not a good design practice. Please describe your use case in more details.

Now I'm working on IOT smart home / sick pacient control using esp32 and remotexy cloud, doed anyone worked with heart beat sensor in remotexy environment??

Have anyone worked with Max30102 sensor let us know?

Aaymen ammari Have anyone worked with Max30102 sensor let us know?

techielew•2/17/24, 4:57 PM

What do you need to know about the MAX30102?

onkyAPP•2/17/24, 4:57 PM

Since you have said you are from PICMG I have one interested topic to discuss. This thing is going on my mind since last few months.

onkyAPP•2/17/24, 4:58 PM

In simple words-
A modular approach like PICMG for Microcontrollers.

onkyAPP•2/17/24, 4:58 PM

There are many MCU manufacturers are out there but this domain is not standardized, however this domain is very cost sensitive.

onkyAPP•2/17/24, 4:58 PM

I am already working on something like this, I cannot say as a standard. I am thinking to use PCISIG M.2 form factor for MCU.
Main reason to select this because the connector for M2 are available dirt cheap in the market. and By using just Mechanical specs of M.2 standard I can design a module of MCU and design carrier for any application.

onkyAPP•2/17/24, 4:58 PM

I am already designing a PCB prototype for this. (in my free time)

onkyAPP•2/17/24, 4:59 PM

I want to keep the form factor & same pinout then have multiple modules with any MCU from TI, STM, Microchip or anything else.
However I have limited work experience, so I am slow in the process.

Ttechielew What do you need to know about the MAX30102?

aymen ammari•2/17/24, 4:59 PM

How can I adapt its code to the ready to use remotexy code

did u end up making the finished version?
