Web16 feb. 2024 · The datasheet is recommending around 360 to 390 ohms but 330 ohms should also be ok to test with one side to your optocoupler output and the other to +5 volts. Add a 330 ohm resistor between pin 6 and pin 8 of your optocoupler. This will now create a logic 'high' for this output. Then add another 330 ohm resistor between pin 7 and pin 8 of … Web19 nov. 2024 · Hello, I’m experimenting with STM32F401CCU6 based board. As mentioned here it should be close to DISCO_F401VC target.. The problem is an attempt to program it from VS Code + Platformio (both newest versions) using St-Link.. The code is compiling and building, but not uploading to target.
