Modified:
trunk/include/peripheral/adc/adc_channels.jal
trunk/tools/adc_channels.jal.tmpl
trunk/tools/adc_channels_generator.py
Log:
add "adc_pin_ANx_direction = input" statements according to the number of
selected ADC channels. This adc_channels.jal lib is looking like a monster,
fortunately it is generated. Is it Frankenstein ?
