Arduino for STM32

I found the cause. (Additional circuit diagram) url: https://drive.google.com/file/d/1sUG4Njh6N8fxbmLm5A1JxwvhqjxqI6ch/view?usp=sharing - MR1: Shunt resistance - L4,L5: Bead resistance (0 ohm~1 ohm) - Directly connected to ADC to measure current. After removing L4 and L5, the problem disappeared. It...

‘MCU basic current’ increases after PWM operation. - core: https://github.com/rogerclarkmelbourne/Arduino_STM32 1. If there is no operation, the total current of 0.07A flows. 2. Turn on PWM - (source code)pinMode(PA6, PWM); pwmWrite(PA6, 5000); 3. Turn off PWM - (source code)pinMode(PA6, PWM); pwmWr...

Thank you for your interest.


1. It works well via Serial (UART).
2. The 'CM1107' board is capable of UART communication and I2C communication.
- If 'CM1107 R/T' is 0VDC, it operates through I2C.
3. It does not work when communicating via I2C.

Thank you for your kind explanation.

thank you so much. You are an angel.

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...
