Posted on May 07, 2014 at 09:18I intend to implement a single touch key using stm8 touch library. I am having few issues regarding this.
I haven't used the shield concept for noise immunity, so what does a need to define for : SCKEY_P2_DRIVEN_SHIELD_MASK in the configuration file.
&sharpinclude''stm8s.h''
&sharpinclude''stm8_tsl_api.h''
&sharpdefine LED1_GPIO_PORT (GPIOB)
&sharpdefine LED1_GPIO_PIN (GPIO_PIN_4)
void main()
{
LED1_GPIO_PORT->ODR |= (uint8_t)(LED1_GPIO_PIN);
LED1_GPIO_PORT->DDR |= (uint8_t)(LED1_GPIO_PIN);
LED1_GPIO_PORT->CR1 |= (uint8_t)(LED1_GPIO_PIN);
LED1_GPIO_PORT->CR2 &= (uint8_t)(~(LED1_GPIO_PIN));
TSL_Init();
sSCKeyInfo[0].Setting.b.IMPLEMENTED = 1;
sSCKeyInfo[0].Setting.b.ENABLED = 1;
sSCKeyInfo[0].DxSGroup = 0x01;
while(1)
{
TSL_Action();
if (sSCKeyInfo[0].Setting.b.DETECTED)
{
LED1_GPIO_PORT->ODR &= ~(uint8_t)(LED1_GPIO_PIN);
}
else
{
LED1_GPIO_PORT->ODR |= (uint8_t)(LED1_GPIO_PIN);
}
}
}
Also here is the main file code , I am not too clear about the validity of this code too. Please provide me help on this issue.
Thank you.
