Detailed Description
Macro Definition Documentation
◆ I2C_FREQUENCY_100K
| #define I2C_FREQUENCY_100K (0x01980000) |
100kHz
Definition at line 122 of file common/i2c.h.
◆ I2C_FREQUENCY_250K
| #define I2C_FREQUENCY_250K (0x04000000) |
250kHz
Definition at line 124 of file common/i2c.h.
◆ I2C_FREQUENCY_390K
| #define I2C_FREQUENCY_390K (0x06200000) |
390kHz
- Note
- : This value is not documented in datasheet. It provides ~390kHz clock with correct timing.
Definition at line 129 of file common/i2c.h.
◆ I2C_FREQUENCY_400K
| #define I2C_FREQUENCY_400K (0x06680000) |
400kHz
- Note
- : According to datasheet, there is HW bug which prevents MCU from generating correct timings, therefore it might be unusable. Use I2C_FREQUENCY_390K instead, if this affects you.
