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...
I don't use the internal Step Down regulator. How should the pins be tied?Should VDDSMPS be tied to VDD and VSSSMPS to GND with VLXSMPS and VFBSMPS left open?OR - should they ALL be left open?Documentation only speaks as if they are to be used - no c...
We designed a custom made board based on NUCLEO-U575ZI-Q schematic. Specifically, we copied the USB-C connection part including the TCPP01-M12. The design is BUS powered. The devices are only recognized if connected via USB-A to USB-C adapters or if ...
Hi, i encountered the problem on my stm32 G474RE board, that when i use the adc in dma mode i can not use a dac. The dac simply does not work. As long as i dont start the adc in dma mode, my dac is generating the right waveform, but when i start the ...
