Arduino for STM32

Hi ag123,

Checked the code - all works and measured voltage and temp fine - thank you!

That helped with the original snippet - it has a typo - ADC_CR2_TSEREFE instead of ADC_CR2_TSVREFE

Once fixed, the snippet works too.

Hi ag123,
thank you for the reply! Your code compiled fine, thanks a lot. I'll test the actual voltage measurement asap and place the results here.

Question - what do do with a calibration procedure in the original code?
adc_calibrate(ADC1);


RE "example you linked is for libMaple / Roger's ...

Glad it worked... Not sure I understand the requests... Button functionality is separate from the encoder one, so you can use the encoder without a button and https://www.arduinolibraries.info/libraries/analog-multi-button completely separately.

Or do you want the encoder library to handle more ...

FYI - I made this one https://github.com/i998/ClickEncoder_STM32 for my MapleMini project, worked ok for me.
Hope it helps.

Hi,
Do you know if STM23F1 (Maple Mini) has an internal source for voltage reference - like Arduino Pro Micro:


// an built-in reference, equal to 1.1 volts on the ATmega168 or ATmega328P
//and 2.56 volts on the ATmega32U4 and ATmega8 (not available on the Arduino Mega)

analogReference ...

FYI - I made an updated version of a ClickEncoder library by 0xPIT so it can be used with STM32 LibMaple Core:

Hope that helps.

Hi All,

I believe many of us needed to make an application that, in fact, does some basic things:
- Get input from a user
- Collect data from other sources like sensors
- Process the information and display the results based on the data captured and/or user input provided
- Rinse and Repeat ...

FYI - I made a version of a library for SSD1306 displays with I2C interface to use with STM32 LibMaple Core:
https://github.com/i998/SSD1306_i2c_STM32

It uses a pointer to I2C object ( I use hardware I2C on Maple Mini) in order to reduce potential problems with redefining Wire etc.

Hope that ...

Hi All,

What is the correct way to use hardware and software I2C on Maple Mini board with the Roger Clark's core ?

There are
Wire.h (that apparently has an issue 858
Wire_slave.h that was recommended as a solution ( update - tested and works)

and
TwoWire that I use as a hardware I2C as ...
