| − | === IO Voltage ===
| + | |
| − | | + | |
| − | RK3568 have three IO voltages, 1.8V/3.3V. For ROCK 3, the high level voltage of GPIO pin on 40-PIN HEADER is 3.3V.
| + | |
| − | | + | |
| − | <pre>
| + | |
| − | | GPIO | Voltage Level | Tolerance |
| + | |
| − | | ---------- | ------------- | --------- |
| + | |
| − | | GPIO3_C0 | 3.3V | 3.63V |
| + | |
| − | | ADC_IN5 | 1.8V | 1.98V |

| − | | + | |
| − | === GPIO number ===
| + | |
| − | | + | |
| − | Rockchip RK3568 GPIO has 5 banks, GPIO0 to GPIO4, each bank has 32pins, naming as below:
| + | |
| − | | + | |
| − | GPIO0_A0 ~ A7
| + | |
| − | GPIO0_B0 ~ B7
| + | |
| − | GPIO0_C0 ~ C7
| + | |
| − | GPIO0_D0 ~ D7
| + | |
| − |
| + | |
| − | GPIO1_A0 ~ A7
| + | |
| − | ....
| + | |
| − | GPIO1_D0 ~ D7
| + | |
| − | | + | |
| − | For Rockchip 4.19 kernel, the GPIO number can be calculated as below, take GPIO4_D1 (PIN26 on 4-0PIN HEADER) as an example:
| + | |
| − | | + | |
| − | GPIO4_D1 = 4*32 + 3*8 + 1 = 153
| + | |
| − | (A=0, B=1, C=2, D=3)
| + | |
| − | | + | |
| − | To set GPIO4_D1 output
| + | |
| − | | + | |
| − | cd /sys/class/gpio
| + | |
| − | echo 153 > export
| + | |
| − | cd gpio153
| + | |
| − | echo out > direction
| + | |
| − | echo 1 > value # output high
| + | |
| − | echo 0 > value # output low
| + | |
