Dear ST Forum members,I am developing the Prototype with STM32WL microcontroller to which I provide a schematic snippet below:+ SWD 1x5 goldpin connector:If the image quality doesn't let you inspect the nets, I will provide a better image later.The 3...
I was reviewing the schematic for the STM32H7x3I-EVAL board and noticed that the ETH_nINT pin from the Ethernet PHY is connected to pin PG7 of the microcontroller.I'm having trouble finding clear documentation on how this pin functions. Could someone...
I’m designing a minimal breakout board for the STM32H757IIT6 to power it up and access a few GPIOs. The purpose is purely learning both about the STM32 dual-core system and PCB design. Since I’m a beginner, I’d like suggestions on anything essential ...
Hi,I am designing a custom board based on the STM32H753, and as part of the design process I am reviewing the MB1246 and MB1331 evaluation board schematics for reference.While studying the display interface, I noticed the following discrepancy:On the...
I am currently designing a custom board based on the STM32H753 microcontroller, and I am studying ST’s evaluation boards as reference designs for the external SDRAM interface. While comparing the schematics of MB1246 and MB1331, I noticed a discrepan...
I’m using an STM32 board to drive an SSD1322 128×64 OLED display with my own driver library. It used to work fine without issues. Without changing the code, the display suddenly became completely unresponsive. - Power supply shows 0A current draw (no...
Dear Experts,Greets,I trying to program STM32F103RCT6 micro controller using NUCLEO-F103RB evaluation board , but I am unable to debug and flash the code , i tried all the possible ways but , it didn't worked .Can somebody help me to solve this . Bes...
I try to connect by usb cable via stm32cubeprogrammer to new board but windows not see any st-link interface. older st-link v2 work fine but this on boad interfave not work. Com's led light on green and red colour. led 5VLD12 on green display work - ...
Removed the ST-Link plastic jumpers and all four pins are free now - as shown on the blue rectangle. As well as, the yellow rectangle shows the 6 pins of CN4 on one column.It seems that pins 1 and 3 are 3.3 V and GND respectively based on the use man...
Hi,I'm buiding a custom board which involve STM32H753XIH6 and IS42S32800J-6TLI, I noticed that STM32H7B3-EVAL schematic has the following:The SDRAM (IS42S32800J-6BL) does not use A12 and A13 — only A0–A11 are connected.The Bank Address pins (BA0, BA...
