This is a question about the Ethernet communication switch circuit. https://cafeptthumb-phinf.pstatic.net/MjAyNDAyMjlfMjYy/MDAxNzA5MjExNDIzMDUw.FUkoobkPXoc0vWl2FJ2P5CEN-zcrQff39TkB_tBLKPYg.OExkMTF0FcwYxmfZqEsmyG8cyUoip9rZVvpWRTedllkg.JPEG/fig.jpg https://img1.daumcdn.net/thumb/R1280x0/?scode=mtistor...

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 l...

[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? https://cafeptthumb-phinf.pstatic.net/M...

Thank you for quick response.

Is it possible without STM32F103 'crystal'?

hello. Nice to meet you.
Looking at the circuit diagram, we confirmed that it was implemented without a 'crystal' or 'oscillator'.

Q1) Is it possible to operate without ‘crystal’?
Q2) Is there a way to code in 'Arduino IDE'?

I wonder. help me~.
