Ürün Bilgileri
Ürün Genel Bakış
TS-GEVB is a touch switch shield evaluation board. It demonstrates LC717A00AR which is a high‐performance, low‐cost capacitance‐digital converter LSI for electrostatic capacitive touch sensor, especially focused on usability. It has 8 channels capacitance‐sensor input. The built in logic circuit can detect the state (ON/OFF) of each input and output the result. This makes it ideal for various switch applications. The calibration function is automatically performed by the built in logic circuit during power activation or whenever there are environmental changes. In addition, since initial settings of parameters, such as gain, are configured, LC717A00AR can operate in stand‐alone mode when recommended switch pattern is applied. Since LC717A00AR has a serial interface compatible with I2C and SPI bus, the PCA9655E is used to provide provides 16 bits of GPIO expansion through the I2C‐bus and SMBus, detecting outputs of LC717A00AR's 8‐input capacitance data and measuring it as 8‐bit data.
