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 ...
Howdy,I’m running into an issue trying to re-flash the original code onto the control board (STEVAL-DPS334M1, which uses the STM32F334R8T6 MCU) for the ST totem-pole PFC board (STEVAL-DPSTPFC1).I’m using an ST-Link V2 with STM32CubeProgrammer to down...
I am Using STM32U5G9J Dk2 board. I want to work with the TSC EOAIE interrupt. But some how i am unable to enbale the interrupt for the same. I couldnt find any HAL API related to TSC too. And in the STM32cue IDE when I try to debug the TSC registers....
How many uart channels are available on STM32H573I-DK Discovery kit.I am Looking for atleast two channels..Thanks in advance...
I am a beginner, and this is my first time trying to use UART to send data from MCU to PC.I try to follow the deep blue embedded tutorial (STM32 Serial Print & Monitor (UART Data Debug), however the console does not receive anything when I connect to...
Hello,I'm working on a daughter board to connect with STM32F769I-EVAL, no problem if it is obsolete. I can't find good CAD resources for the item, I need a step 3D file or a pdf with the position and the height of all components, so I can design my b...
Hi everyone,I'm trying to measure the current consumption of the MCU/NPU on a NUCLEO-N657X0-Q board. According to the reference manual (https://www.st.com/resource/en/user_manual/um3417-stm32n6-nucleo144-board-mb1940-stmicroelectronics.pdf - see par....
