raichen WROTE:hi there.. i tried to develop a device known as transcutenous electrical nerve stimulator. this device generate electrical current in digital signal pulsed and sent to skin surface using electrodes to kill pain. the original circuit of the device does not have any display, anyone of you know how to attach display into it? since this is analog device, so it is difficult to implement it. really needs help from expertise in analog circuit.. please
raichen WROTE:did you mean output from the oscillating switches uses as input to the MCU unit? and that for displaying the frequency selection? And then output from the step up circuit uses as analog input to measure amplitude of pulses? both of this then being displayed? is that right?
raichen WROTE:how about the voltage that is varied using variable resistor.. the voltage would be around 9 -80v like that? my intention is to display the voltage selection, freq and also pulse width.
