谁用过STM32L152CBT6做线性触摸板的？
谁用过STM32L152CBT6做线性触摸板的？#define MCKEY1_A_CH (CH1) /**< Multi channel key 1: 1st channel port */
#define MCKEY1_A (GROUP1) /**< Multi channel key 1: 1st channel mask */
#define MCKEY1_B_CH (CH1) /**< Multi channel key 1: 2nd channel port */
#define MCKEY1_B (GROUP2) /**< Multi channel key 1: 2nd channel mask */
#define MCKEY1_C_CH (CH1) /**< Multi channel key 1: 3rd channel port */
#define MCKEY1_C (GROUP3) /**< Multi channel key 1: 3rd channel mask */
请问里面的A、B、C是对应相应的ＧＰＩＯＡ、ＧＰＩＯＢ、GPIOC？还是只是一个便于区分的标号。我现在用的PA0、PA6、PB0。PA1、PA7、PB1做线性触摸条怎么也没得反应。是不是必须得使用GPIOC啊？
