MDK 5.25下载: https://armkeil.blob.core.windows.net/eval/MDK525.EXE
据说 MDK 一个最重大的更新 V5.25版本, 下载下来试一试.

Re: 测试 物联网俱乐部 STM32L431RCT6开发板外设

工程路径: STM32Cube_FW_L4_V1.11.0\Projects\NUCLEO-L432KC\Examples\GPIO\GPIO_IOToggle\MDK-ARM\Project.uvprojx

修改 stm32l4xx_nucleo_32.h:

#define LED3_PIN                           GPIO_PIN_13
#define LED3_GPIO_PORT                     GPIOC
#define LED3_GPIO_CLK_ENABLE()             __HAL_RCC_GPIOC_CLK_ENABLE()  
#define LED3_GPIO_CLK_DISABLE()            __HAL_RCC_GPIOC_CLK_DISABLE()  

可以点亮板子上的LED PC13

发现一个问题, STM32L431进入休眠模式之后就没有办法调试了,Keil出现了错误。
现在正在搜索有没有办法解决这个问题。

Cannot access target. Shutting down debug session.

Re: 测试 物联网俱乐部 STM32L431RCT6开发板外设

按照 tickless-mode.c 这个链接修改, 加入

HAL_DBGMCU_EnableDBGStopMode();

然而,并没有什么用处。

暂时不研究这个问题了, 现在研究 AT 指令与 BC95  模块通讯.

Re: 测试 物联网俱乐部 STM32L431RCT6开发板外设

做了一个简单的UART2(PA2, PA3)收发串口信息的demo:
UART2_TwoBoards_ComPolling_BC95.7z

解压到这个位置: STM32Cube_FW_L4_V1.11.0\Projects\NUCLEO-L432KC\Examples\UART

与CH340交叉连接,发现电脑可以收到UART2发的信息,但是电脑发的信息UART2确收不到.

明天继续调试。

JTAG/SWD 有没有选择正确呢? 电源有没有问题呢?
