Arduino for STM32

128 Mhz is probably above the cpu clock frequency e.g. for stm32f103c8 72 Mhz, you can probably at best get like 72 Mhz or more commonly half or less like 36 Mhz. for the 'official' STM core, the wiki is here https://github.com/stm32duino/Arduino_Core_STM32/wiki hardware timer API is documented here...

for this board/chip, note that you would need the 'official' STM core https://github.com/stm32duino/Arduino_Core_STM32 https://github.com/stm32duino/Arduino_Core_STM32/wiki in part has it has the full STM32 HAL stack in tow, a fat footprint, but that is the reason the 'support' is bundled. and you c...

happy new year

it may work if you #include "todayLib.c" instead ( of "todayLib.h" )

Accordingly, tolerant pins have diodes that sink currents, but they still require a high enough resistor to limit the currents going into the pin.
For non-tolerant pins you are taking your chances

if you use st-link (and only with st-link) , there is a method called connect under reset. i.e. press reset on stm32f103 board, and try to flash using st-link v2 accordingly, it is one way to override write/copy protection if indeed the device is locked. Normally to do those things I use Opencd from...

for the (old) libmaple (roger's) core use this repository for the core https://github.com/rogerclarkmelbourne/Arduino_STM32 there is a wiki here https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki but you still need the st-link v2 dongle to program the board / chip. it is likely 'harder' to se...

Try using this core instead, deemed the 'official' STM core https://github.com/stm32duino/Arduino_Core_STM32/wiki/Getting-Started https://github.com/stm32duino/Arduino_Core_STM32 https://github.com/stm32duino/Arduino_Core_STM32/wiki and to program that board stm32f103c8, you would need a st-link don...

these days, for *convenience*, and with microcontrollers with generous sram and flash, some don't even bother with c/c++ and simply script away. https://micropython.org/ https://circuitpython.org/ e.g. if you have a good library, writing to a sd card can be simply f = open("file.txt","...

it is possible to write assembly, but that c/c++ codes tend to be more readable and maintainable. in terms of savings, you can possibly write / make smaller binaries with assembly. But for my purpose, as I'd rather simply get a chip with a more comfortable margin of sram and flash, I'd make do with ...
