New Adafruit STM32F205 board with wifi

Postby ddrown » Fri Mar 25, 2016 4:37 pm

https://www.adafruit.com/products/3056 - $35

It's supposed to have support for TLS 1.2 (which esp8266 does not), which is needed for things like talking to Amazon's MQTT.

They also started with the Maple base for Arduino support. Their code is at https://github.com/adafruit/Adafruit_WICED_Arduino

They also have a bunch more information about it here: https://learn.adafruit.com/introducing- ... i/overview

Downside is the broadcom wifi chipset firmware and interface library is binary only, but that's unfortunately normal for wifi.

Interesting

Using the old Maple F2 code seems an odd way to go about a new commercial project

Two things I just think about:
1) Observe their code, it's Adafruit they didn't have done everything wrong with their libraries (on the contrary!)
2) Give them a hint, that the STM32duino code is FAR further developed than the leaflabs original one. It would be a nice thing to give Adafruit some code back.
Sadly it's a niche product, so they won't do much further with the board.

Ok, if I have time tomorrow I'll do 2) and leave them a message on github. Edit: done.

Thanks Matthias

Its interesting to see the responses

I thought that F2 support was originally part of libmaple, ( there are lots of references to it in the core), but I'm not sure how stable it ever was. ( which is why I thought it odd that they used libmaple for their product)

The F2 part was definitely of the original core, but I think it was added "later" (after official support stopped 2 or 3 years ago), like (later) the nucleo STMF103 (which I have completely rewritten because of many mistakes), so I guess there were some "blueprints" for further projects, which were never realized.
It would be a cool thing if Adafruit is going to dig more into STM32, I'm sure we would get a big benefit out of it. *wishful thinking*
It's really a funny thing: There is no "big company" behind STM32 *duino:
AVR-ATmel = Arduino
Microchip = Digilent (chipkit)
TI = Energia (=Robertinant, but "official" linked by TI)
but STM32?

Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers soldered in
Light as a (large?) feather - 5.7 grams
STM32F205RG 120MHz ARM Cortex M3 MCU
BCM43362 802.11b/G/N radio
128KB SRAM and 1024KB flash memory (total)
16KB SRAM and 128KB flash available for user code
16MBit (2MB) SPI flash for additional data storage
Built in Real Time Clock (RTC) with optional external battery supply
Hardware SPI and I2C (including clock-stretching)
12 standard GPIO pins, with additional GPIOs available via SPI, UART and I2C pins
7 standard PWM outputs, with additional outputs available via SPI, UART and I2C pins
Up to eight 12-bit ADC inputs
Two 12-bit DAC outputs (Pin A4)
Up to 3 UARTs (including one with full HW flow control)
TLS 1.2 support to access secure HTTPS and TCP servers
On board single-cell LIPO charging and battery monitoring
Fast and easy firmware updates to keep your module up to date
Based on the excellent community-supported Maple project
Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE.


So, go back to Adafruit product page and click on the hyperlink in the line I highlighted above. I think Ladyada already knows about us! Roger, you have been forked!

LOL

Thanks Ray

I didn't realize that our repo had been forked by Adafruit, I presumed that they'd forked the original version.

Interesting, IMO, She did remove every

I do not know when they pulled their version. I loaded up MELD earlier today and did a directory compare:
/home/ray/Arduino/hardware/Adafruit_WICED_Arduino/stm32/cores/maple/
/home/ray/Arduino/hardware/STM32/STM32F1/cores/maple/

Adafruit changed (edited) almost everything. It may be interesting on some cold rainy day to do a file-by-file compare to see if there are may additions (there are additions) that would bring value to our core without breaking anything. According to one of statements made in an advertisement, the project took 1 year to complete.

Did they really remove the Leaflabs copyright !!

I wonder if they have an agreement with Leaflabs about that.

(BTW. As far as I know the Leaflabs guys were working for Google last time I looked at their site.
