前言
一、移植目标
二、移植资料准备
1.simpleFoc源码
2.获取Arduino 下的stm32f1x的驱动层
总结
由于之前用的是自画的odrive板子,移植的 simplefoc,驱动用的drv8301。逢上嘉立创免费打样,闲暇之余,重新学习了FOC整个过程。准备再次深入了解simpleFoc和odrive,比较他们的细节差异。画了两版simpleFoc:
一版为SimpleFOCShield(单路):stm32f103cb+L6234D
另一版为SimpleFOC-PowerShield(双路):stm32f405G+btn8982。
上图:
SimpleFOCShield版
嘉立创贴片中仿真图还未出
SimpleFOC-PowerShield版
将Arduino里的 simpleFoc移植到gcc下,驱动层用STM32CubeMX生成,并且以arduino里应用层框架进行调试。既然用STM32CubeMX生成驱动,那么就要了解arduino里相应stm32f1x驱动细节,驱动逻辑上先保持原汁原味及一致性,只是写法要变得直接和简化,个人感觉arduino里驱动层太应用层化,并且冗余。
编译环境使用 gcc+vscode+STM32CubeMX,整个编译框架采用了odrive编译模型。目录结构如下,后续文件及文件夹有更新再上传到github

通过Arduino IDE下载Simple_FOC-2.3.0.zip,如图
windows下,运行cmd通过git获取驱动层源码
git clone https://github.com/stm32duino/Arduino_Core_STM32.git
232芯片一般都有两路,那么在原理图设计时,就拉了两路串口,设计思路:串口1,使用printf函数可以打印些自己需要的调试信息。串口2,调给simpleFoc里的print。
在第一章节里目录结构Board目录下建立stm32cubx_mx工程,目录层次如图
建立基本工程,主要是启用串口1作为printf输出
在main.c里添加代码
/* Private user code ---------------------------------------------------------*/
/* USER CODE BEGIN 0 */
int _write(int fd, char *ch, int len)
{
HAL_UART_Transmit(&huart1, (uint8_t*)ch, len, 0xFFFF);
return len;
}
/* USER CODE END 0 */
/* USER CODE BEGIN 2 */
HAL_GPIO_WritePin(run_led_GPIO_Port, run_led_Pin, GPIO_PIN_RESET);
printf("hello my simplefoc coming...\r\n");
printf("SystemCoreClock = %lu\r\n",SystemCoreClock);
//setup();
/* USER CODE END 2 */
编译下载,成功
这样编译框架基本建立,关于编译环境配置细节,可以去网上搜Odrive编译环境搭建,下一章节将会移植 simplefoc的print,因为这个在编码器,电流检测,pwm里都有调用。
