Resolved! B-L475E-IOT01A2 does not emulate STlink V2 upon power on, but red and green LED are present
HiI am a little bit lost on this particular discovery board. I connect it via CN7 (STLink V2 connector), and jumper settings are as supposed. The user guide says that LD6 should be red, and LD5 should be green. LD6 blinks red, and LD5 is constantly g...
STM32F401 won't start
I have a 3x4 matrix keyboard attached to STM32F401, see schematics (the U4 represents a "black pill" PCB). PB0, PB1, PB2 are column outputs in push-pull mode. PC15, PA0, PA1, PB10 are row inputs in EXTI mode with pull-ups enabled.The circuit worked a...
Resolved! Is it possible to swap some FMC address and data pins for a custom pcb?
Hello,is it possible to swap some address pins or is it necessary to follow up the pin given in the datasheet?Lets say i need to change that FMC_A0 does not go to PF0, it should be connected to PF1, and FMC_A1 connected to PF0.And for data i need to ...
Inter-channel interference occurs when reading multi-channel adc.
hellow.I tried to read multiple adc using stm32h743, but I had great difficulty due to inter-channel interference.I tried to read multiple adc using a simpler "NECTULEO-L073RZ" to find out what the problem was, but the same problem occurred.Please he...

Why do newer STLINK V2/ISOL display a lower voltage than older ones?' Why does new hardware look different and works different
We have already received 2 deliveries of STLINK V2/ISOL from well-known suppliers, which display a lower voltage and also partly do not work with our products.Unfortunately, we have not yet received an answer from support and currently do not know ho...
STLINK-V3MINIE how to adapt the 14 pin 1,27mm spacing cable to a more convenient 2,54mm spacing connector?
STLINK-V3MINIE how to adapt the 14 pin 1,27mm spacing cable to a more convenient 2,54mm spacing connector? I only can found 10 pin or 20 pin adapters and not the 14 pin adapter as used on the STLINK-V3MINE
STM32F446RET6 - can't program it through SWD
Hello,I received my STM32F446ret6-based PCB for my student project, PCB was already assembled from the JLCPCB factory and I can't program it through the SWD header with ST-link. I checked every trace on PCB with schematic and measured continuity with...
