[STM32F103C8T6] How can I use '128 Kbytes of Flash memory'?3

hello. Nice to meet you.

When coding, ‘flash memory’ is important.

Is there any way to increase the flash memory to '128 Kbytes'?

Q1) Do I need to change the chip number?
Q2) Or is there another way?

officially u'd need to get a stm32f103c{b,B}t6, that one has 128 k per specs, c8 is 64k per specs.

So if you think you literally have 128k memory, you can try a variant for 128k e.g. maple mini.
The details are actually in the ld script, check in there in the variant.

Alternatively, get something like a stm32f401/f411, these has more like 256k flash, and 64k sram.

sram matters just as much, in fact more so than flash. and f4xx is much faster for the same mhz (has 'ART' accelerator (on chip cache) and FPU)
