| 00:13 | cbxbiker61 | i2c pullups are usually in the range of 4.7k - lk, not too critical of a spec, 4.7k would almost always be just fine |
| 00:15 | cbxbiker61 | i go with 4.7k, just in case multiple devices on the i2c bus have pullups, then the overally impedance goes down |
| 07:12 | jnettlet | vpeter, you can program those pins to be either a pullup or pulldown. By default we have them configured as being pulled up. MX6QDL_PAD_KEY_COL3__I2C2_SCL 0x4001b8b1 MX6QDL_PAD_KEY_ROW3__I2C2_SDA 0x4001b8b1 |
| 07:12 | jnettlet | well that is i2c2...but i2c3 is configured the same |
| 08:45 | vpeter | jnettlet: I'm talking about external pullup - there are two wires and resistor between this i2c pins and +3.3V. But not on schematic. Is schematic little old? |
| 08:46 | vpeter | And I know how i2c works (did few projects long time back with micocontrollers). |
| 08:46 | jnettlet | vpeter, those schematics are up to date |
| 09:06 | vpeter | Then why I have two resistors on wires? |
| 21:37 | vpeter | jnettlet: Are you using some wifi ac card on clearfog? I'm not sure which one should I buy (supported on openwrt). |
