Topic: STM32F103 still an ongoing option? (Read 1 time) previous topic - next topic

Hi All,

I have been experimenting with some Arduino ~compatable alternatives like ATMEGA644PA and recently looking into the impressive STM32F103 which is a very cheap but powerful processor.
I was very impressed with the STM32 option but concerned that it looked like it might be end of life with both STM32duino sight going read only and leaflabs discontinuing the maple/mini range.
Does anyone know if there is still active development  or active community to keep them ardiuno compatable etc?

They seem amazing and first tests of blue pill is great but I don't want to invest a lot of time on product development to find I was the last guy to learn cobol :)

the manufacturer ST Microelectronics took over the stm32duino development and forum http://stm32duino.com/viewtopic.php?f=16&t=4671.

the boards package has Boards Manager installation

Great thank you, worth a look for some of my bigger projects then.

That news about (temporary) break in Arduino support for the STM32F103 completely passed me by.
I have one production project, a satellite dot matrix clock,  which uses an STM32F103 (Bluepill) and 4 unused ones waiting for a suitable project - they were so cheap I bought 5). For the satellite clock, the additional serial ports and the builtin RTC with minimal standby power consumption were useful.

However, there is a bit of a learning curve and the initial set up is not completely trivial. I seem to remember having to register at a site to download a bootloader and some interface software. I never got to understand the architecture to the same extent as with the AVR architecture (direct manipulation of hardware features such as  timers, ADC etc.) and in the meantime. the cheap and powerful ESP devices have come along.
