MIKROE-2564

      Keylock click PID: MIKROE-2564 Keylock click carries a processed sealed key lock mechanism that can be set in three different ositions. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over the PWM, INT, and AN pin on the mikroBUS™ line. The key can be removed from the lock in any of the three positions. The package contains two keys and one protective cap. Keylock features The contact mechanism provides unequaled logic-level reliability and smoother, positive detent actuation. Detent mechanism, with its spring-operated steel ball, gives crisp, positive action for accurate switch setting. Specifications Type  Joystick  Applications  Use the three different positions of the mechanism to turn applications on or off, for  home security applications, for industrial equipment, etc.  On‐board  modules  Keylock switch with 3 positions  Interface  GPIO  Input Voltage  3.3V or 5V  Click board size  S (28.6 x 25.4 mm)  Pinout diagram This table shows how the pinout on Keylock click corresponds to the pinout on the mikroBUS™ socket (the latter shown in the two middle columns).

Code snippet This is a simple example of how Keylock click works, depending on the state of the Keylock click the appropriate position will be detected. 01 02 03 04 05 06 07 08 09 uint8_t state; char txt[20]; void systemInit() { ANCON0 = 0x00; ANCON1 = 0x00; ANCON2 = 0x00; UART1_Init(9600); 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 } void Keylock_Init() { KEYLOCK_STATE_1_Direction = 1; KEYLOCK_STATE_2_Direction = 1; KEYLOCK_STATE_3_Direction = 1; } void Keylock_Task() { state = KEYLOCK_STATE_1*1 + KEYLOCK_STATE_2*2 + KEYLOCK_STATE_3*3; UART1_Write_text("Keylock is in state:"); IntToStr(state,txt) ; UART1_Write_Text(txt); UART1_Write_Text( "rn" ); delay_ms(500); } void main() { systemInit(); Keylock_Init(); while( 1 ) { Keylock_Task(); } }                                                    https://shop.mikroe.com/keylock‐click 9‐29‐17
