STM8 Core

[RogerClark]

Guys

I see there is some interest in the STM8 processor, with Armduino porting their core to this (8 bit) architecture, so I thought it was worth making a section of this even though its not a STM32 device, and is quite a different type of device.

I just received a couple of these

"STM8S103F3P6 ARM STM8 Minimum System Development Board Module For Arduino" boards from eBay, for $1 each.



PS. I love the way the eBay vendors add the word "Arduino" to the end of virtually everything, even if there is not an Arduino core for such a device

I bought 2 differents boards, the most common blue one with STM8S103F3P6 and another that is red, it is lesser common and use an STM8S003F3P6. As I wrote earlier, my metal STLINK dongle didn't work but the Baite model instead worked perfectly. Then I used SDCC but compiled only a blink example.

But it simplifies the search! Using the single word Arduino you find a lot of results that are interesting. Try to search using ARM, you will get a looot of results that are not useful.

True.


I got some other interesting stuff in the post, including some IR time of flight distance measuring modules, but I'll need to post that to my Postbag

But why? STM8 is obsolete, isn't it?
Almost the same (package and price), but 32 bit and more peripherals:

It is dirt cheap.

For some reason the STM8 still seems really popular with manufacturers

Possibly its he knock down price.

I think STM8 has sold 3 billion of them and still get massive sales figures

Lots of low end devices still use them.


Personally, I'll mainly be using the STM32 but some devices I want to reverse engineer and modify have STM8's in them

i'm starting to be happy again i once ordered some cheap tiny stm8 boards. might end up doing something with them after all XD.
looking forward to this

it is indeed obsolete, in terms of specs.

it is anything but obsolete, in terms of its market share.

I think some people are working on the Armduino core to get it to work on the STM8, and have some success

I'm not sure whether the STM8 is arm or not, so perhaps the name of that core does not suit this use, but the name doesnt matter that much ;0)

oops, followed links above

Looks like it only sips a few mA when it is running. There appears to be a low power version that sips even less.
