Can a meshtastic device be made with STM32L151 and SX1232? How can it be done?

[universish]

I have 5 pcb cards containing ARM STM32L151 microcontroller. They are defective cards developed by the Baylan measurement company developed to read the water meter.

Apart from the STM32 microcontroller, there are 32,000 4-leg crystal, 13,560 2-leg crystal, FM1702SL N9A31R2G microchip, SX1232 1629 86816 microchip, mifare antenna, RF ID antenna. There is also an LCD, but it can drive old type LCDs with very low resolution. The LCD can fit 20 character letters.

A pcb for remote reading of water meters.

Can I make a meshtastic communication device with the components on these boards?

Can a meshtastic node device be made?

Sadece SX1262 radio mikroçipi mi kullanmam gerekiyor? SX1232 uygun değil mi?

I can develop software if the hardware is suitable. Unless, of course, there is no written software.
Is software available for these hardware?

ARM STM32L151RDT6
https://www.st.com/en/microcontrollers-microprocessors/stm32l151rd.html
Ultra-low-power 32-bit MCU Arm® Cortex® -M3, 384KB Flash, 48KB SRAM, 12KB EEPROM, LCD, USB, ADC, DAC, memory I/F, 63/64-pin BGA/LQFP/CSP

The STM32L151/152 devices extend the ultra-low-power concept with no compromise on performance, using the Cortex-M3 core and a flexible CPU clock from 32 kHz up to 32 MHz. As well as the dynamic run and low-power run modes, two additional ultra-low-power modes bring you very low power consumption while keeping an RTC, backup register content and low-voltage detector.

The STM32L151/152 devices are designed for medical, industrial and consumer applications and feature an onboard fast 12-bit 1 MSPS ADC, USB 2.0 FS and capacitive touch sensing. You may extend the memory range using the SDIO and FSMC interfaces.

To reduce application cost and design, the STM32L151/152 offer an integrated LCD driver with up to 8 x 40 segments.

The STM32L151/152 portfolio offers from 32 to 512 Kbytes of Flash and from 48- to 144-pin packages.

Would this hardware be suitable for the meshtastic device? Since it has ultra-low power consumption and 3 different power modes, it could be a good hardware for meshtastic. It can run an 8x40 LCD drive so I can also see messages on its own screen. I can connect it to my smartphone and use it from my smartphone. Because it also has USB2 support. Maybe I can connect it to my PC and use it. Can I do that? Is the hardware suitable for that?
I would like to connect a keyboard but I don't know how.

Neither the MCU nor the radio chip are compatible with Meshtastic, sorry. And it's not a matter of tweaking the software to make it work, the MCU lacks resources needed and the radio chip lacks about any possibility of control we need. It's made for lorawan, not lorap2p

[universish]

Why do you need BT and/or Wireless MCU? Isn't a radio microchip enough to run LoRa? Why do we need WiFi or BT, or do we need it? Can we do without it?

[caveman99]

To run on stm32 we need at least 512 KB of flash. That's the lack of resources I am talking about. Also the SX1302 does not work with meshtastic. Period.

Can I find a list of suitable MCUs or MPUs for meshtastic? I have searched but I couldn't find any.
What are there besides nRF52840, ESP32-S3FN8, RP2040, ESP32-C6, RP2040, ESP32 WROOM? What are the STM32 MCU/MPUs that may be suitable?
Does it have to support BT and WiFi?
What are meshtastic compatible radio microchips? Is there a list? What can be used besides SX1262, SX1276, LR1121, SX1280, LR1110?
Which MCU/MPU and radio microchip do I need to make a meshtastic node? Is there a list of suitable hardware?

https://meshtastic.org/docs/hardware/devices/
All the microcontrollers that are used in the supported devices are microcontrollers that Meshtastic supports. As well as the radios. Generally the radio needs to have an SPI interface and a TCXO to be compatible.

[universish]

I already know these. I'm asking about the ones other than these. I'm not talking about ready-made devices and pcb cards. I'm talking about microchips and MCUs.

[madeofstown]

I'm talking about microchips and MCUs.

I am too. The devices on that page contain THE supported radio chips and microcontrollers. There may be people experimenting with other chips but they aren't supported by Meshtastic until they get a pull request merged.

[universish]

Where can I see pull requests and merges?

Maybe you should just do some looking around. You're already on GitHub so maybe explore a little bit in the Meshtastic repos, specifically the "Pull Requests" tab... You can also do some Google searches for how git and GitHub work.

ok, thanks
