Enumerations | |
enum | I2C_status_t { I2C_STATUS_OK = 0, I2C_STATUS_TIMEOUT = 1, I2C_STATUS_BUSY = 2, I2C_STATUS_NACK = 3 } |
Status values returned by the I2C read/write commands. | |
Functions | |
void | I2C_init (void) |
Initialize the I2C peripheral. | |
void | I2C_enable (void) |
Enable the I2C channel. | |
void | I2C_disable (void) |
Disable the I2C channel. | |
void | I2C_mode_normal (void) |
Connect SDA and SCL pins to the I2C peripheral. | |
void | I2C_mode_gpio_input (void) |
Switch I2C pins to GPIO mode Disconnect SDA and SCL pins from the I2C peripheral. Configure them as GPIO inputs (in order to avoid unintended input signals to the I2C peripheral that will cause it to freeze) | |
void | I2C_peripheral_recover (void) __attribute__((deprecated)) |
Recovery procedure according to XMC1100 Errata Sheet. | |
int32_t | I2C_read (uint8_t addr, uint8_t *data, uint8_t count) |
Read a number of bytes from an I2C device to a uint8_t array. More... | |
int32_t | I2C_write (uint8_t addr, const uint8_t *data, uint8_t count) |
Write a number of uint8_t bytes to an I2C device. More... | |
void | I2C_wait_transmit (void) |
Wait for an I2C transmission to end. More... | |
void | I2C_write_recover (void) |
Write FF (the recover value) to the I2C Bus. | |
void | I2C_write_reset (void) |
Write 00 (the reset value) to the I2C Bus. | |

int32_t I2C_read | ( | uint8_t | addr, |
uint8_t * | data, | ||
uint8_t | count | ||
) |
Read a number of bytes from an I2C device to a uint8_t array.
Read count bytes from the device with the given I2C address to the data array
addr | I2C device address. |
data | Address where the data should be stored. |
count | Number of bytes to be read from the device to the data array |
void I2C_wait_transmit | ( | void | ) |
Wait for an I2C transmission to end.
Blocks the program execution until the last I2C operation is completed.
