EEPROM

提供AT24Cxx系列EEPROM芯片的数据读写函数,内含页写自动管理

依赖库:https://github.com/netube99/si2c

#include "eeprom.h"
#include "si2c_port.h"

si2c_t si2c;
si2c_port_t port = {GPIOB, GPIO_PIN_7, GPIOB, GPIO_PIN_6};

Si2c_Init(&si2c, &port);
Eeprom_Init(&si2c);

uint8_t buf[16] = "hello eeprom";
uint8_t rbuf[16];

if (Eeprom_Write(0x0000, buf, sizeof(buf)) == EEPROM_SUCCESS)
{
    Eeprom_Read(0x0000, rbuf, sizeof(rbuf));
}
