Re: [all cores] F4+F1: ABP1 timer clock frequency

If it could help, I've implemented a function to get the correct freq depending of the TimX clock source and the system clock config for all MCU series: https://github.com/stm32duino/Arduino_Core_STM32/blob/c392140415b3cf29100062ecb083adfa0f59f8b1/cores/arduino/stm32/timer.c#L668 It uses some HAL_* ...

Re: Erratic Behaviour of the Standard Arduino I2C Bus Scanner

Ok, reproduce on F411.
Always relies on IT mode.
This will be fixed with https://github.com/stm32duino/Arduino_C ... issues/217

Re: Erratic Behaviour of the Standard Arduino I2C Bus Scanner

Hi Francois,

I've tested your code and it works with the disco L475 IOT board.
I will try tomorrow with the F411, I will not surprised to reproduce your issue... :roll:
There is a regression on I2C since it was moved to use IT mode. An issue is opened for this.

Re: Access the PC register through ST-Link V2?

Ensure to have aggressively cache compiled core disabled in Arduino preference Select Debug in Optimize menu. Then after building your sketch: Launch st-util Launch gdb with the generated elf: <yourpath>/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin/arm-none-eabi-gdb yourbuildsketch.elf In gdb exec: targ...

Re: i2c slave receiver: nucleo 64 F401

I've made some tests with F401 and it works if you do not change line 541 in twi.c from: nbData = I2C_TXRX_BUFFER_SIZE - obj->handle.XferCount; to: nbData = I2C_TXRX_BUFFER_SIZE - obj->handle.XferSize; As mentioned I2C slave required some review since the mode to IT mode. An issue is already open fo...

Re: [SOLVED] STM32L072 from Arduino IDE

Welcome
sorry for this issue, I did not test with standard installation path. :roll:
On Windows, I install Arduino in a short path without space to avoid any issue with path length or space...

Re: STM32L072 from Arduino IDE

Hi davidb, there is an issue with the last release when path contains space. Mainly when Arduino IDE is installed in its default directory "C:\Program Files (x86)", The "'Files' is not recognized as an internal or external command, operable program or batch file." comes from this. It will be fixed i...
