Hello,i intend to use a STM32H725IGK6 device in my design.The system will be suplied from a single 3.3 voltage source.Apart from VDD,VBAT pins, i see this device has some VDDLDO pins, and 3 VCAP pins.How shall i power the vddldo pins? Can i tie them...
Hi, I work for a CEM in the UK and we've run into a problem when reflowing an STM32H757XIH6 BGA onto a PCBA. Under optical microscope inspection we're seeing that the center of the component is further away from the PCB surface than the corners. The ...
Hello,I apologize if this is an obvious question, but I do not want this part to be wrong and would prefer some confirmation.I am preparing a custom board and would like to program it in an identical manner to the evaluation/nucleo boards. To try and...
Hi,Any program on my stm32f439zi board does not start when I supply the voltage from the external power supply at 3.3V, unless I connect the programmator via USB cable to the computer as well. When I disconnect the USB cable the program continues its...
Hi, This is Soyoung.ST-LINK/V2 - Can you confirm this activation product??The case was white, but it is yellowish as shown in the picture.Please let me know if the case changed.I wait for your reply.Thank you.
Currently doing academic research.There are few descriptions in the specification, how to measure CMRR?
Hi, I at a high level I have designed a program to toggle the user LED on PA5 if a gpio input sees a high signal (shorter than 150ms) on PA0. The program works well most of the time except in some instances when it will miss an input pulse entire...
A web search tells me I have a problem! My STM32 target has a MIPI10 connection for SWD debugging which works great with my I-jet probe. I now need to use an STLink but none of the supplied cables are for a MIPI10 target. Where can I buy such a cable...
I connected the 5v input of usb-ttl to the 5v output of the MPU, while the mpu was plugged into the computer and suddenly smoke came out. Now I get 2.8V from the 5v output of the MPU, 2.5v from the 3v output. Also in the debug circuit, r4,r10,r11,r14...
