Resolved! In the STM32H723zg dev-kit, are all the pins of ZIO connector present in the MORPHO connector?
In other words, is the Zio a subset of the Morpho?
STLINK_V3_SET not connect to STM32H745
Hello,I am working STM32H745 controller. I am trying to connect STLINK_V3 SET to my customboard. But I getting the errors I am attaching the images ,I set the Debug as serial wire and device is in Connect Under Reset. What things I have to check, als...
Resolved! STM32F413 Discovery Kit- Where can I find the schematics for the evaluation board ?
Working on interfacing with the evaluation board however I don't know where any I/O is mapped.For example CN9 PC0 what gpio is this mapped to ? What I have done with other MCUs is reference the evaluation board schematic to know the corresponding pi...
USB to STM32L451RET6 with FT231XS-R is there a schematic for this ?
I have the STM32L451RET6 and i would like to integrate it to my PCB. This PCB is directly connected to a PC over USB. So to communicate with the STM32 i need a FT231XS-R. So i am not sure how the schematic looks like.
"Error: Initializing the option bytes failed" when trying to connect with device in dfu mode
Hi all,I'm using STM32F767 Microcontroller.For flashing FW to the controller I'm using STM32CubeProgrammer through USB DFU mode.By making the BOOT pin high, I tried to connect the device with programmer through USB.Then I observed the error screen po...
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...
