[SCM] KBD_RDCHR DL : 0: The function kbd_rdchr() does not riqueres interrupts or timers. Just call it when your program needs to read a key, it also does not queue those keys in any way. This function handles a 3x4 matrix keyboard conected at port defined as "kdb_port" kdb_port pins from 7 to 4 manages col from 1 to 3 kdb_port pins from 3 to 0 manages row (also lines) from 1 to 4. It is possible to deal with a 4x4 matrix keyboard just changing "kdb_cnt_col" variable value from 3 to 4. Manoel Gomes de Andrade andrade.manoel(AT)gmail.com

[Other Embeded program] an144_files DL : 0: CodeLockAVR electronic combination lock is realised with Atmel AVR microcontroller AT90S2313. Program in hex code is 2 kB long. User code is consisted of 1 to 4 digits. If the code is entered in the correct sequence, then after 1 second the relay and the electric striker (in the door) switch on for 1 second and then switch off again. User code can be changed via 3x4 matrix keypad. Keypad can be bought at local electronic shop. Initial user code (1234) is set up with a jumper. The jumper must be inserted before the voltage (12V) connection. The jumper must be removed after 2 beeps.
