【米尔MYD-YA15XC-T开发板试用体验】使用STM32CubeIDE 测试Cortex M4内核GPIO

2021-12-28 08:44:11 8729 米尔

米尔MYD-YA15XC-T开发板接口丰富，几乎把核心板全部接口引出，而且按照功能进行归类排布，非常方便测试。STM32MP1 是 ST 推出的首款 Cortex-A7 +Cortex-M4多核异构 MPU， A7 可以运行 Linux 系统，借助 Linux 系统庞大而丰富的软件组件处理复杂应用，比如 UI 界面、网络应用等， M4 内核的优势就是实时性，因此可以在 M4 内核上运行对于实时性要求严格的应用，比如电机控制、无人机飞控等各种控制算法。 M4 也可以运行各种 RTOS 操作系统，比FreeRTOS、 RTThread 等。

x1 2x25_2.54mm 间距双排针（显示 RGB888、触摸、I2C、PWM）
x1 2x10_2.54mm 间距双排针（DCMI）
x1 2x10_2.54mm 间距双排针（SDIOx1，UARTx1）
x1 2x10_2.54mm 间距双排针（GPIO，USBx2）
x1 2x20_2.54mm 间距双排针 RPI 接口（SPIx2、UARTx2、I2Cx2、CANx1、SAIx1）

STM32MP151 的 GPIO 有 GPIOA 至 GPIOK 和 GPIOZ 共 12 组 GPIO，其中 GPIOA~GPIOK每组有 16 个 IO，而 GPIOZ 有 8 个 IO。所有的 GPIO 均带有中断功能，所有的 GPIO 都可以被Cortex-M4 和 Cortex-A7 共享访问，而 GPIOZ 可用于 TrustZone 安全性相关的设置（当用于此项时仅限于 Cortex-A7 访问），相关的外围设备的软件访问被定义为安全性访问，常用于安全解决方案中。

STM32MP151 的 GPIO 可以由软件配置成如下 8 种模式中的任何一种：
1、输入浮空
2、输入上拉
3、输入下拉
4、模拟输入
5、具有上拉或下拉功能的开漏输出
6、具有上拉或下拉功能的推挽输出
7、具有上拉或下拉功能的开漏式复用功能
8、具有上拉或下拉功能的推挽式复用功能
每个 GPIO 引脚都可以通过软件配置为输出（推挽或漏极开路，带或不带上拉或下拉）、输入（带或不带上拉或下拉）或外围设备复用功能。
