Arduino for STM32

Thanks for the additional comment - on a different PC it works with only the hal_conf_extra.h so a cache issue does seem possible.
In any case all working now, I appreciate all the comments

Thanks everyone, tried again today and the combination of changing HardwareSerial.h and hal_conf_extra.h seems to have cracked it

Many thanks... It seems obvious now you pointed it out :oops:

Changed to:

#if !defined(SERIAL_TX_BUFFER_SIZE)
#define SERIAL_TX_BUFFER_SIZE 256
#endif
#if !defined(SERIAL_RX_BUFFER_SIZE)
#define SERIAL_RX_BUFFER_SIZE 256
#endif

Uploaded and tested, but the buffer still shows as 64 in the ...

Hi

I'm running an STM32F407VET using UART to another uC (on same PCB) and would like the option to change the buffer from 64 bytes to 256.

I've tried to follow the guidance at https://github.com/stm32duino/Arduino_Core_STM32/wiki/Custom-definitions#serial-rxtx-buffer-size

What i have ...

Thanks so much, I'm happy debugging now....

Is it possible to use the debug function in Arduino IDE?
- I have STM32F4 and am using ST-Link V2 to program id via SWD, but can't get it to work (tbh I've never used the debug function before so it may well be operator error!)

Thanks so much

Thanks to you both for responding - That has set me on the right track and I've figured that out, now pulling about 3.2mA, Job done!! :D

I would still like to understand how to set the PeripheralPins and Clock settings in the sketch too, haven't figured that out yet, but after you set me on the ...

Hi all

Forgive the relative noob question, and go easy!
I have an existing custom board that was programmed previously with CubeIDE (of which I have almost no experience) by a retired engineer, that I have successfully re-written a simplified functional version of in Arduino IDE (due to a needed ...
