Re: Hola, soy Edu. Felíz Navidad!!

En efecto ese chip tiene muy buenas prestaciones. Es muy parecido al F746IG de la placa Core7XXI. Para que la entiendas mejor empieza por instalar el Core STM32 1.9.0, ya que el actual (2.3.0) viene muy complejo, aun me enredo demasiado con la nomenclatura del pinout. He intentado varias aproximacio...

Re: Hola, soy Edu. Felíz Navidad!!

Es bueno saber que hay más entusiastas de estos micros. Bienvenido.

PD: las dos placas STM32 que me llamaron mucho la atención por sus dimensiones son la blackpill F407VG y la Core7XXI

Re: LCD

Recalling the initial post, creating an EEG implies you draw several simultaneous lines 5, 6 or 7. The simplest graph is solved by drawing one screen at a time, starting on the left and ending on the right and erasing at the end what you have drawn overwriting again from left to right. The displacem...

Re: F_CPU for STM32F4

It is not directly a parameter that you can modify, within the variant.ccp file of each MCU, the clock configuration parameters are defined.

To estimate F_CPU, they use this formula:

Code: Select all

(Input frequency / PLLM) * (PLLN / PLLP)

Re: st7920 - 128x64 Blue back light LCD .

Try the U8g2 library, it seems to me that it is compatible with STM32. Newer versions of this controller chip work over the SPI bus. Just make sure that the pins are located correctly, the pinot nomenclature of the LCD does not follow the SPI standard

Re: SD Card Using SPI2

For the F401 Board, the SPI2 bus pins are different from those of the Nucleo F767. I think you can use these lines for F401CC: //port 2 --> bus SPI2 on F411CE or F401CC static SPIClass mySPI2(PB15, PB14, PB13); #define SD2_CONFIG SdSpiConfig(PB12, DEDICATED_SPI, SD_SCK_MHZ(18), &mySPI2) Remember...

Re: SD Card Using SPI2

It is not as simple as replacing one line with another, you must create another constructor but with the pins of the second port, so that the STM32Test example points to the correct pinout of the other SPI bus (2, 3, etc). In this example coded for a Nucleo F767, the first port is the SPI1 bus, the ...

Re: SD Card Using SPI2

Have you tried using the SdFat library? The latest version can be used with STM32 boards. You just have to configure the correct pinout and the appropriate call for the type of microSD on the SPI bus that you want to use. For example, for exFat cards, on a F411CE board connecting the reader on the S...

Re: Black Pill with adafruit ST7789

There is no way I still do not get an answer with the duo ST7735+F103C8, I have already tried with very different screens connected to SPI1 ... please fpiSTM , will you have an example to guide us to know how to use the spi bus with a screen that can be controlled by GFX-style adafruit libraries + T...
