Arduino for STM32

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 ...

You can try to install this: https://www.st.com/en/development-tools/stsw-link009.html Thanks I downloaded this and installed it. Made no difference I still have no COM port assigned to the STM32 in Device Manager. I should have noted STM32 Cube Programmer is installed. This is with the STLink plug...
