-==== More details about 40-pin Header ====
+== Resource ==
-* Pins marked with color orange are designed for debug console.
-* PWM:x7,PWM0/PWM1/PWM2/PWM3/PWM6/PWM7/PWM11
-* SPI:X2,SPI0/SPI3
-* I2C:X2,I2C2/I2C4
-* UART:X2,UART0/UART2
-* ADC:X1, SARADC_IN3
-* I2S:X2, I2S1/I2S2
-=== IO Voltage ===
-RK3566 have three IO voltages, 1.8V/3.3V. For CM4 IO, the high level voltage of GPIO pin on 40-PIN HEADER is 3.3V.
-<pre>
-| GPIO       | Voltage Level | Tolerance |
-| ---------- | ------------- | --------- |
-| SARADC_IN3    | 1.8V          | 1.98V     |
-</pre>
-=== GPIO number ===
-Rockchip RK3566 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
-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
+* [[Rock3/CM3/raspcm4io/gpio | Raspberry Pi CM4 IO Board GPIO]]
- echo 153 > export
- cd gpio153
- echo out > direction
- echo 1 > value     # output high
- echo 0 > value     # output low
