This weird circuit is a programmable, analogue PSU. It is basically only a LM317 and an array with resistors and MOSFET’s so I can program the voltage out by selecting a combination of 10 resistors. This is not straight forward, but I can at least Select 10 preset values. In addition I use an ADC…
Many of my newer devices have CAN so I wanted a simple USB(CAN adapter. It is nothing special with this project. I used a STM32F105 with USB on one side and CAN on the other. A minimalistic UDB-CAN Adapter just6 to avoid the need to pay a fortune for these. The first rev 1.0 missed…
The logic for driving these stepper motors are straight forward as you apply 4 or 8 steps. The 4 step logic is faster and you rotate in a circle CW or CCW: Step 1: 0 + 1 Step 2: 1 + 2 Step 3: 2 + 3 Step 4: 3 + 0 This will create…
