Arduino for STM32

Hello,

Did try to change the load of input 1 to 4.

Can upload now, get this:" no matching function for call to 'I2C_eeprom::readBlock(int&, DAC_Input*&, unsigned int)'"
Do i need to change also the writeBlock?

Again, thanks for your help.

Thanks.
I will update soon and i get back.

Because STM32duino is not an Arduino. It's similar, mostly compatible, but it's not the same. There are differences in data types and how they behave, in some math functions, etc. It's the difference between C++ and Arduino. Crap, i was hooping that i missed a line or two when i made the convert fr...

if your storage needs are modest, and your sketch (the compiled bin file) is *small* , you may want to try using a stm32 chip with lots of flash like 256k. things like stm32f401ccu may be 'adequate' https://www.st.com/en/microcontrollers-microprocessors/stm32f401cc.html of course, bigger chips like...

Hmm, got it, But prog works perfect on Arduino Due. Can’t understand why it wont work here when in download ok on stm32…

I’m a real noob on this. And just eeprom seems to be really hard for me to understand

Pointer? I dont follow…

Thanks for your help.

Hello. Yes i have pullups on both lines. I did as you adviced and made a small program just to store a value in eeprom. I used extEEPROM.h. Worked perfectly so now i know that extEEPROM can be used. When i think about it both I2C_EEPROM and extEEPROM hangs at the same time in program. That’s when se...

Hello and thanks for the help.

I did try to paste code here but prog to big.

@GonzoG Can i send a link to you with PM?

Hello again, I've tried I2C_EPPROM by Rob that was suggested from GnozoG (Thanks). Still doesn't fly for me. I have the same problem as with extEEPROM. I run a example code from I2C_EEPROM that scanned the memory and all seems fine, addres 0X50, 32K, 1 device.... But in my program i download fine an...

Aha, Thanks.
Will have a look at it.
