    hi, here i am again....i'm trying to let ADC and comparator work together, the adc seems to work fine, i have problems with the comparator: also setting the edge on PA4 with a resistor divider at 1.6V, the comparator takes the edge at 2V. i have joined the inputs PA5 for the comparator and PA6 for the ADC together to start the converter when the comparator output goes high. in the cose i set the following registers for the over functions to analog pins:

    hwreg(0x400D4090)|=0x1; pa4 analog

    hwreg(0x400D4094)|=0x1;pa5 analog

    hwreg(0x400D4098)|=0x1;pa6 analog

    it seems the pull-up default settings on the ports have highest priority on ours.


    moreover, could i set the over functions combined? for example 0x3 to ana|pde?

    thanks and sorry for my english
