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...
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...
Hi I'm using STM32G0B0RET6, and im using ADC Channel 1,4,5,6,7,10,11,15, and 16 . and sequencer is set to not fully configurable because if set to fully configurable then i can't use Channel 15 and 16.So here for all ADC channels i'm getting same val...
I am using the debugging mode in STM32CubeIDE, and the compilation result shows that there is insufficient RAM.27_Touch_Appli.elf section `.bss' will not fit in region `RAM'region `RAM' overflowed by 94904 bytes
hello, I have a can bus with 2 node (one STM32G0B1 with SN65HVD1050DR transcriver and one esp8266 with MCP2515 module) that comunicate over canbus at 1Mbps.I am trying to add a third node, it is a blue pill STM32F103C8T6. The chip onboard looks genu...
I am using an STM32H757 for a composite USB device with a ULPI HS PHY. I am streaming video data to the device via an OUT endpoint from the host PC (Windows 11). Streaming can be successful for more than 15 minutes but then the host suddenly stops se...
Hi, On STM32G071CBU6, when PB15 is used as CC2 with DBCC2 shorted to CC2, does the ROM bootloader ever drive PB15 as SPI2_MOSI, or does the CC/dead-battery own the CC2 pin and that path always takes priority? This detail is critical for our design be...
Hi,I am experiencing issues with UART single-wire (half-duplex) communication on an STM32H723. The UART handler reports error code 4 (frame error). I have tried a wide range of configuration settings without success.The same setup works correctly on ...
I'm currently looking at something like thisSTM32N657A0But they sell a non AI accelerator version STM32N655A0Is there any benefits to using the non AI version of the chip. Other then saving a few dollars on the chip?
