That is Edited version of Original version for stm32
usage:
define GPIO in i2c_sw.h
:
#define GPIO_SW_I2C1_SCL GPIOB
#define GPIO_SW_I2C1_SDA GPIOB
#define GPIO_SW_I2C1_SCL_PIN GPIO_PIN_13
#define GPIO_SW_I2C1_SDA_PIN GPIO_PIN_14
That example is for stm32f103
, for use other micro replace #include "stm32f1xx_hal_gpio.h"
in i2c_sw.h
.
This library has the ability to activate more than 10 software I2C , which have been commented in this library, but by default only one of them has been activated.
Example:
#include "i2c_sw.h"
int main()
{
SW_I2C_initial();
i2c_port_initial(SW_I2C1);
while(1)
{
//Write DATA to Reg at Reg_Addr from I2C_Add Device connected to SW_I2C1
SW_I2C_WriteControl_8Bit(SW_I2C1,I2C_Add,Reg_Addr,DATA);
//Read DATA at Reg_Add from I2C_Add Device connected to SW_I2C1
DATA=SW_I2C_ReadControl_8Bit(SW_I2C1,I2C_Add,Reg_Add);
}
}
