My STM32H533VE works as PD Sink.We connected CC1/CC2 with DBCC1/DBCC2 (as AN5225), STM32 cannot power up with a USB PD adapter. The adapter supplies power for ~20ms then stops the supplying.If I remove the long time initialization code (LSE initializ...
I have designed a STM32H723 board with LAN8742A PHY IC and its connected to a Hanrun HR911105A Magjack. I am running the Ethernet stack on mongoose network library. The stack is working perfectly on a STM32H7 Nucleo Board, the link auto-negotiates to...
I designed a board that uses a STM32H750 with a USB3300-EZK that has stopped communicating over USB. It's been having intermittent issues for the last day or so (sometimes I'd need to power cycle the board before it would show up, but then it would w...
This is my first foray into STM32. I bought a couple of WIOE5 lora modules. This post will not let me post links to the the WIOE5 datasheet. I bought an STlink V3mini from Waveshare. There is not a datasheet available from waveshare. I downloaded STM...
Hi,I’m trying to read internal temperature sensor on ADC1, but the ADC result is always 4095.I use STM32L471, and I know that the problem is not HW related, when I run a different bin it reads the temp ok.Tried to read VREFINT, raw value is also 4095...
STM32f103In the design guide it recommends to have something switching between vcc and gnd with 10kOhm series resistor, and i need my design to be grounded by default so i may not solder the header even, is it okay if i left the design like fig 1 ins...
Hello everyone!I am using stm32n6570-dk. My project has only FSBL and was generated using STM32CubeMX. I was able to run it in debug mode without issues. The code does not execute when flashed to external flash memory. I had to comment out "MX_ICACHE...
When using stm32n6 and enabling both GFX and AI models, the runtime continuously reports errors:"Epoch controller error interrupt: EC_IRQ = 0x00000008 Epoch controller opcode counter: 0x00000000 Epoch controller tag: 0x00000000 ATON_STD_IRQHandler()@...
Hi all - I am building an isolated power converter using a three phase forward converter topology. Each phase has a half bridge driving a transformer primary w.r.t. Vin/2 (split Vin). The transformer has a mid-tap secondary, rectified effectivel...
I'd like to use the DTCM ram in my code; how can I do ? Thank you
