Re: "Generic STM32F0 series" does not run with LTO

Tried these #define's (except TIM because it's used by something) together with USART enabled (because my project uses serial port). This gave me only 500 bytes for some reason. UPD: Tried the same on a very early version of the sketch, which does almost nothing and lets me to disable serial port c...

Re: "Generic STM32F0 series" does not run with LTO

By default the HAL config loads everything and the modules are a bit heavy, especially for MCU's with low flash. The ST core allows you to change the default HAL config by creating an " hal_conf_extra.h " file on the same folder as you sketch and there you can disable everything that you don't need/...

Re: Problem creating new Variant STM32L151C

Probably the clock config. @fpiSTM are you able to give me more detail? I can't seem to solve this, I used the SystemClock_Config(void) that worked in STM32CubeIDE can you give me anything else I can check? Thanks Hi, you could check if there is a pin naming error, instead of a blinking sketch you ...

Re: How to use STM32 boards with Arduino IDE and how fast ESP32 vs STM32 are they? (incl. surprise)

It's a very good video but I think that Andreas isn't really familiarized enough with the STM32 platform, for example, he didn't mention that add support for a "not listed" MCU it's super-easy on the ST core and he says that if an MCU/board isn't listed there is not support for it, also I always use...

Re: Continued issues with WeAct STM32F411

I made a "black pill" with the F411CEU and duplicating the variant since it wasn't clear what HSE clock was the variant using... just overwriting the .id file and the clock config function (my board uses an 8MHz crystal) for what the stm32cubeide creates and I didn't have any problem so far with my ...

Re: stm32f030f4p6

Yes, I like the F030 series, the ST core supports the F030F4 already, but you can easily add support for other MCU, I think that support for the F030C8 will be added on the next core release and as you already saw, the MCU's are cheap on Ali, the only downside it's the flash (mostly on the F030F4-1...

Re: Clock frequency change

Hi, 60mA seems quite a bit for a normal STM32 mcu, for a L (low power/consumption) version seems too much, maybe the problem it's on something else. The datasheet for the STM32L476 mcu says that the power consumption it's 100uA/Mhz, that's 8mA at 80MHz. Also, the nucleo boards I think that includes ...

Re: Nucleo-F030R8 and ILI9341 Changing SPI Speed

Try this library:

https://github.com/Bodmer/TFT_eSPI

I'm using it with and F030C8 and the ST7735 display, on some of my tests I got about 10x better speed than the standard adafruit libraries :D

Re: IRF7103 and 3.3V control with STM32

I thought IRF7103 for 3.3V control is not a good choice. Thanks for the hint with the AO3400A transistor. I checked if it is available where I live (aliexpress is stopping the project for 1-2 months), I found it. I also found AO4800, it seems to have exactly the same pin distribution as IRF7103. Th...
