The same <SPI. 1 BSY bit may stay high when SPI is disabled Description The BSY flag may remain high upon disabling the SPI while operating in: • master transmit mode and I have found the connection between chip pins and elements on the board (for example the buzzer is connected to the pin number 13, "PA3") but I have a problem. 3V and two 5V pins helps. 5 inch lcd and second spi port is for Windfond Serail Flash memory - w25q32 . i change the pin number of CS,DC,RST,TOUCH_CS according to my connection #define TFT_CS PC15 // Chip select control pin to TFT CS #define TFT_DC PC13 // Data STM32 SPI Programming. 2nd Note: Just a nitpick. My Idea was to remap the Pins: Code: Select all #define LED_RATE 500000 // in microseconds; should give 0. In a later case make sure to deassert nCS What are the default SPI ports compatible with arduino on this board MISO --> PB_5 ? MOSI --> PB_4 ? SCLK --> PB_3 ? SS --> PA_4 ? I've the same problem with an I'm using all the pins on that board, and it's a bit of a waste having to look at the code (e. Learn more In this tutorial, I’ll show you how to set up SPI using STM32CubeIDE and communicate with an external EEPROM chip. 5. setModule(2); e. LED on PA13 is connected to It depends on how you use the SPI object. SCK <--> PA5 <--> BOARD_SPI1_SCK_PIN. The SPI pins has to go to the hardware SPI pins (normally SPI1 default). Just connect the corresponding pins on the ST-LinkV2 clone to the STM32duino. TWI is the AVR name, the peripheral in the STM32F103 is called, unsurprisingly, I2C. c HI I recently make a remote control that includes a ILI9341 and a ds1307, I try to liberate 3 ADCs by remapping the ILIILI9341 to the SPI1 alternate pins, the ADCs pins are now available and working and the ILI9341 works Good day all, I would just like to know how to redefine SPI pins. Top. h lib with the second SPI on an STM32F103 - but I'm failing. How to do it depends on which core Now, let’s configure the SPI interface on the STM32 microcontroller.
