Arduino for STM32

In Arduino its showing as

STM32F1XX/GD32F1XX Boards by stm32duino.

I have Selected Generic STM32F103C6/fake STM32F103C8T6

Hi,

I have tried below code to test the simple byte function and read the same.

Circuit is connected to port and I2C Scanner is detecting Chip @ 0x50 Address. Working @ 3.3V. WP on AT24C32 Pin is left open.

What else could be issue ?


#include <Wire.h>

#define EEPROM_ADDRESS 0x50 // I2C ...

I have made Custom board with Simple ST-Link v2 pins out 34/37 and power. Program does gets loaded using Arduino STM32 Core and SL-Link v2 Successfully shows download and led indicates accordingly.

But 7 Segment doesn't light up.

Same Hardware if i program through non STM32 Core and program via ...

Hi,

On PA0, PA1 and PA2 are define as input with Pull up enabled. as per below code, but when i push the button LED on PC13 Turns off instead of being turned on.

what could be wrong ?



bool START = 0, STOP = 0, RESET1 = 0;


void buttons()
{
START = digitalRead(PA0); //START BUTTON
STOP ...

Okay,

I had success using 2 Instances, i think this library can use any PINs as BITBANG @ SPI. so you can use multiple sensor only drawback would be 3 pins would be wasted. better option would be to use CS to multiplex sensors saving IO pins.

can i use multiple instances of max6675 ? that should work ?

Thanks got it,

But any idea how to run 2 SPI @ same time ?

Hi,

I am looking for resources on internet but not getting results for interfacing MAX6675 to SPI using STM32F103C8T6.

Can anyone please help me out where to start for using K-Type Thermocouple IC MAX6675 to read temperature from 2 Modules on SPI1 and SPI2.

I am using STM32 Arduino Core for ...

Hi,

I have developed a custom PCB for our application.

i have replicated everything regarding the programming Jumpers and programming pins as we do in STM Blue Pill through Arduino.

some how i am unable to program the new chip.

Question in my mind is do we need to load bootloader for programming ...

Tested and it works as expected with STM32 core.
If you use STM32Core, which version and which target you select in arduino menu?

Sorry for late revert,

STM32Core is 2022.9.26

Target board is Generic STM32F103C using Bluepill STM32F103C8T6
