in 2003. In 2006, Stef Mientki initiated the development of a new version, JALV2, which was programmed by Kyle York and beta tested by an international user group.Beta testing by: Bert van Dam, Sunish Isaac, Dave Lagzdin, Javier Martinez, Stef Mientki, Wouter van Ooijen, Michael Reynolds, André Steenveld, Joep Suijs, Vasile Surducan, and Michael Watterson

Sample code

-- JAL 2.3 include 16f877_bert--define the variables var byte resist--define the pins pin_a0_direction = input--variable resistor pin_d7_direction = input--switch pin_c2_direction = output--pwm led--enable pulse width modulation PWM_init_frequency (true, true) forever loop--convert analog on a0 to digital resist = ADC_read_low_res(0) -- run measurement through flash memory program_eeprom_write(2000,resist) program_eeprom_read(2000,resist) -- run measurement through data memory data_eeprom_write(10,resist) data_eeprom_read(10,resist) -- if the switch is pressed return random value if pin_d7

high then resist = random_byte end if--send resistance to PC serial_sw_write(resist) delay_100ms(1) -- set actual PWM duty cycle PWM_Set_DutyCycle (resist, resist) end loop
