Re: Problem uploading to STM32F103C8T6 board
(except if I buy one with the arduino bootloader preinstalled, right?). Nope, you got it wrong. First, the thing you have is not a programmer. It's just a converter, from usb to serial ttl. Programmers are a bit different thing. All mcus generally support in-chip programming, for atmega(arduino) it...

Re: Problem uploading to STM32F103C8T6 board
@mrburnette
seems like he already tried serial, cuz he is talking about ft232rl (fake highly likely) usb ttl and call it "programmer"

Re: Options for a lot of cpu clock frequencies.
it will be in the main.c, just copy paste this function to your sketch and add extern "C" like fpiSTM said

Re: EEPROM.put - where does it stores data?
No, bytes you put to flash cant reach your ram
flash area start address is 800 0000 (hex), when SRAM is starting at 2000 0000 (hex)
in decimals it will be 134 217 728 and 536 870 912, hundreds of millions bytes difference

Re: Hardware CAN initialization fails
yes, as HAL is written on C, not C++, you need to use extern "C" {} for redefining irq handlers etc

Re: Options for a lot of cpu clock frequencies.
roger's core allows these frequencies cuz its compatible with usb clocking with this (stm32 official) core (not roger's one) you can configure your mcu any way you wish by overriding weak SystemClock_Config with cumbemx generated where you can play with clock parameters https://i.imgur.com/lrtWNS9.j...

Re: Transfer of values to ArduinoUNO original ports.
inturrupt handler have to be quick as much as it possible and have some rectrictions also, but digitalWrite is very heavy trying to be beginners friendly with tonns of checks and inits inside for interrupt handlers it's much better to use direct writing routines, at least digitalWriteFast for offici...
