SPI is a hierarquical synchronous communication protocol amongst electronic devices. h" #define WREN 0x06 /* Set Write Enable Latch */ #define WRDI 0x04 /* Reset Write Enable Latch */ #define RDSR 0x05 /* Read Status Register */ #define WRSR 0x01 /* Write Status Register */ #define READ 0x03 /* Read Data From Memory Array */ // Workaround for STM32 support #define ADC_CR2_TSVREFE (1 << 23) // from libopencm3 #define digitalPinToInterrupt(x) (x) examples/SecurityPersonalizer does not seem to work. TFT LCD . In the picture above, D is the MOSI, and Q is the MISO. Check out the Official Arduino Libraries or Interfacing With Hardware pages to find more libraries, or find examples in Code Snippets and Sketches. GPIO: For controlling GPIO pins. c,i saw line 184 to 194 ,where spi_eeprom_sample() function placed ,colored in grey-this means CCS discarded this code sample. PS. 04. 18 Responses to “Using Serial Peripheral Interface (SPI) Master and Slave with Atmel AVR Microcontroller” Mar 29, 2017 · @freynder said in STM32?. The code was tested on a LPC2106 evaluation board, which uses a 10 MHz crystal (system clock). In addition, the required bus signals are clock input (SCK), data input (SI) and data output (SO) lines. In this example, you will learn how to communicate to an EEPROM interfaced to the Arduino board via SPI. stm32: Бібліотека для роботи з eeprom типу at24xxx по шині i2c update 01. Half-duplex wiring of STM32 SPI is as follows: STM32 half-duplex SPI connection. h; Src/STM32_EEPROM_SPI. So 0-127, 128-255, 256-383, etc are examples of page boundaries.
