+## ADC Configuration
+
+For now running in matching mode for TS100
+
+- X channels DMA in background
+- Sample tip using "Intereted" channels using TIMER 0,1,3 TRGO or timer0,1,2 channels
+- Using just 12 bit mode for now and move to hardware oversampling later
+- use DMA for normal samples and 4x16 bit regs for tip temp
+- It has dual ADC's so run them in pair mode
+
+## Timers
+
+### Timer 2
+
+Timer 2 CH0 is tip drive PWM out.
+This is fixed at 50% duty cycle and used via the cap to turn on the heater tip.
+This should toggle relatively quickly.
