STM32 PWMing PWM & Injected ADC
In the new release of firmware for the TS100, I have moved the system from using a software-driven bit-bang of the output to hardware-based timers. The issue here is that we cannot just use normal PWM! Why can’t we just use normal PWM? Soldering Iron drive Schematic The above image shows a small extract from the TS100 schematics, with the PWM signal from the STM32. The soldering iron tip is driven by the back to back MOSFETs(Q1A/B)....
