Arduino IDE for Maple r5 program on STM32F103C8 issue

[fpiSTM]

See the wiki to use the board manager of the Arduino IDE.

Thanks, but who knows what's wihi? why not plane English and some elaboration?

Sorry, typo mistake you should read Wiki.
Anyway, I guess it is not so hard to find it:
https://github.com/stm32duino/wiki/wiki

If you take time to read the Readme.md you would find all info you needs....

The WiKi specified above is valuable, but the IDE installation is as explained:

Getting Started

This repo is available as a package usable with Arduino Boards Manager.

Use this link in the "Additional Boards Managers URLs" field:

https://github.com/stm32duino/BoardMana ... index.json

For full instructions on using the "Boards Manager", see the Getting Started page.

Advanced user can use the repository to benefit from the latest development. See the Using git repository page.

User can add a STM32 based board following this wiki.

From the Arduino IDE perspective, this link helps to understand the capability:

https://www.arduino.cc/en/guide/cores

Multiple JSON entries are comma-separated. I have stm32, esp8266, esp32 and a few others! Placing old-style cores without JSON files is still done by placing the core support files in a directory subordinate to <user>/Arduino/hardware just like in the old days; however, for ArduinoIDE to read & load the specifications the directory structure has a pre-defined structure defined in the version 1.5 introduction.

Good luck,

Ray

PS:
The LeafLabs IDE years back was a customized Arduino 0022.
The current IDE has tightened-up many compiler switches and some loosie-goosie coding will no longer successfully compile.

I note that the Maple r5 has/had the 128KB Flash version of the STM32F103C8T6 whereas the STM32 Smart V2.0 specifically has the 64KB Flash version.
You may have problems that software can't fix!
