hello. Nice to meet you. PWM is not output.
help.

GonzoG const byte PWM_PIN[20] = { PA1, PA2, PA3, PA6, PA7, PB0, PB1, PB10, PB11, PB5, PB4, PB3, PA15, PA11, PA10, PA9, PA8, PB15, PB14, PB13, }; #define LED PC13 void setup(){ //------------------------------------------------------------------------// Serial.begin(115200); for (uint8_t i = 0; i < ...

#define BACKLIGHT_LED PB4 void setup(){ pinMode(BACKLIGHT_LED, OUTPUT); analogWrite(BACKLIGHT_LED, 255); } @GonzoG Thank you for leaving an answer. Even if you proceed with the source code as follows, it does not solve the problem. The PWM is connecting to the LED to test its brightness. As far as ...

'STM32F103C8T6' not work PWM Function. https://img1.daumcdn.net/thumb/R1280x0/?scode=mtistory2&fname=https%3A%2F%2Fblog.kakaocdn.net%2Fdn%2FobIUp%2FbtskEoO8HZa%2F1Hwuhkkkgp6yhUPMZFZkv1%2Fimg.jpg hello. Nice to meet you. If you look at the picture, it is marked 'PWM' in 'PB_4'. I tried driving it...

@GonzoG

Wow...

understood at once.
Thank you.
can be used sufficiently.
thank you

@fpiSTM

hello. thank you for the reply.
STM32F103C8

Q1) Does the chip above not have 'EEPROM'?
- I actually tried to write and read the EEPROM to the corresponding chip.
It works fine.
Q2) If there is no EEPROM, how does it work?

On STM32 interfaces have alternate pins. It's done this way so you can choose which pins to use. For example by default U(S)ART1 uses PA9 and PA10, but you change it to PB6 and PB7. Same thing with SPI. By default SPI1 uses PA4-PA7, but if you need those pins as analog inputs, you can set SPI1 to u...

I am curious about the function of STM32F103C8T6 'Pinmap'. hello. Nice to meet you. Please look at the image. https://img1.daumcdn.net/thumb/R1280x0/?scode=mtistory2&fname=https%3A%2F%2Fblog.kakaocdn.net%2Fdn%2FobIUp%2FbtskEoO8HZa%2F1Hwuhkkkgp6yhUPMZFZkv1%2Fimg.jpg - Serial1 : PB_6, PB_7 - Seri...

Thank you.~~!!

STM32 MCUs do not have EEPROM. To have non-volatile memory, virtual EEPROM is created in flash memory. Because every MCU has different memory it virtual EEPROM needs to be configured for each MCU. You're using Roger's/Steave's core, so it's limited to only few MCUs and it may be missing necessary c...
