Re: Can't program F401 after PA9 set as INPUT_PULLUP
if that didn't work, you may need disconnect usb cable press and both boot0 and reset and connect the cable (if you need 'extra hands', try to find out if those pins reset or boot0 can be connected to gnd (reset) or 3v3 (boot0) using jumper/dupont wires. hold boot0 and release reset release boot0 1...

First of all I'm fairly new to STM32, so please excuse my lack of knowledge here... :| I accidentally set "PA9" as INPUT_PULLUP in a sketch and after uploading the sketch I can't seem to program my Black Pill F401 anymore using USB and DFU. It says Error: Target device not found Establishi...

Hi to all, first of I'm new to STM32. Up to now I have only been working in the classic Arduino realm. The need for more ADC and Hardware PWM pins made me switch to a black pill board. Is there any way to use more than the standard 10 adc pins (PA0-PB1) on the F401 BlackPill board? In the documentat...
