参考这篇文章:GPIO模拟SPI
1.首先在内核里面打开SPI模拟
Device Drivers --->
[*] SPI support --->
<*> GPIO-based bitbanging SPI Master
2.在设备树里面根节点下面添加复用的GPIO设置:
spi2: spi2{
compatible = "spi-gpio";
#address-cells = <0x1>;
#size-cells = <0>;
//ranges;
gpio-miso = <&pio 4 3 0>;
gpio-mosi = <&pio 4 4 0>;
gpio-sck = <&pio 4 5 0>;
cs-gpios = <&pio 4 6 0>;
num-chipselects = <1>;
pinctrl-names = "default";
pinctrl-0 = <&spi2_pins_a>;
spidev2@0 {
status="okay";
#address-cells = <1>;
#size-cells = <0>;
compatible = "spidev";
spi-max-frequency = <20000000>;
reg = <0>;
};
};
3.在pio: pinctrl@1c20800 里面添加引脚:
spi2_pins_a: spi2-pins-pc {
pins = "PE3", "PE4", "PE5", "PE6";
function = "spi2";
bias-pull-up;
};
4.注释掉LCD相关设备树内容。
5.将MOSI和MISO短接就可以测试回环数据是否正常,使用 ./spidev_test -D /dev/spidev0.0 -v 来进行测试。
注:这里是使用的LCD引脚,我这边板子已经去掉LCD了。
这个估计和从机也有关,我换了一个其它的SPI传感器(和之前不是同一种传感器),它能够正常使用。
但是之前那个还是不能正常通信,
这就很离谱了。
&pio {
spi0_cs_pins: spi0_cs_pins {
pins = "PC2","PE20";
function = "gpio_out";
};
};
&spi0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins &spi0_cs_pins>;
cs-gpios = <&pio 2 2 GPIO_ACTIVE_HIGH>,<&pio 4 20 GPIO_ACTIVE_HIGH>;
#address-cells=<1>;
#size-cells=<0>;
spidev0@0 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <0>;
};
spidev1@1 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <1>;
};
};
在这种情况下,测试CS、MOSI、MISO脚都是有波形的。MISO没有波形。
修改设备树之后,出现设备,CS脚也能被拉低。
但是通信不成功,不能正常读取从机的芯片ID,请大家帮我看一下,哪里有错误?
1.直接使用默认的SPI(默认CS 为PC2), 检测到有/dev/spidev0.0,能够正常使用。
&spi0 {
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins>;
status = "okay";
#address-cells=<1>;
#size-cells=<0>;
spidev@0 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <0>;
};
};
2.使用GPIO 来作为SPI的CS脚,检测到有/dev/spidev0.0,示波器测得CS脚在运行时会被拉低,但是通信不成功。
&pio {
spi0_cs_pins: spi0_cs_pins {
pins = "PC2";
function = "gpio_out";
};
};
&spi0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins &spi0_cs_pins>;
cs-gpios = <&pio 2 2 GPIO_ACTIVE_HIGH>;
#address-cells=<1>;
#size-cells=<0>;
spidev@0 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <0>;
};
};
3.SPI复用,有多个CS脚。检测到有/dev/spidev0.0 、/dev/spidev0.1 。使用/dev/spidev0.0进行通信,示波器测得CS脚(PC2)在运行时会被拉低,但是通信不成功。
&pio {
spi0_cs_pins: spi0_cs_pins {
pins = "PC2","PE20";
function = "gpio_out";
};
};
&spi0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&spi0_pins &spi0_cs_pins>;
cs-gpios = <&pio 2 2 GPIO_ACTIVE_HIGH>,<&pio 4 20 GPIO_ACTIVE_HIGH>;
#address-cells=<1>;
#size-cells=<0>;
spidev0@0 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <0>;
};
spidev1@1 {
compatible = "spidev";
spi-max-frequency = <100000000>;
reg = <1>;
};
};
找到原因了,是因为在内核配置的时候,没有选中相关的协议。

按理说,在网线插入的时候,/sys/class/net/eth0/carrier 这个文件里面的值就会被改变。epoll_wait 就会监测到,并且去读取这个文件的值。但是知道为什么,我多次插拔网线后,都没有触发epoll_wait,求赐教。。。

@晕哥
救命呀!晕哥,我把模块连接到虚拟机上面,一直找不到蓝牙装置。
我使用命令
sudo ./start_bt.sh ttyUSB0
时,串口模块只有TX会闪烁,RX没有闪烁。
我在V3S上面使用其wifi功能是可用的。

需要烧录正确的设备树, sun8i-v3s-licheepi-zero.dtb
我之前烧录了sun8i-v3s-licheepi-zero-dock.dtb
结果里面就没有文件。
