Hi ST Team,I have completed my first custom board using the STM32H753BIT6, using the H753-EVAL board as a reference. I need to test its external SRAM, SDRAM, Flash, and QSPI, as I have included all the memory components present on the EVAL board. I h...

Hello Team,I encountered an issue while using the ST-LINK GDB server version 7.6.0. The server started successfully, but it failed when attempting to halt the target. Below are the server messages and the steps I’ve taken to troubleshoot the problem:...

Since we have decided to create the prototype, the first requirement is ensuring that the chosen H753-EVL board is functioning properly. However, its GPIOs are already occupied with essential peripherals such as LTDC, FMC-SDRAM, SRAM, NOR flash, USB_...

I have chosen the STM32H743 as the custom hardware chip to manage real-time applications, including displaying analog ECG data on a 1080x600 DWIN display with CTP and using a 24V thermal printer for printing. I need reference schematics for using SDR...

Hi , As i decided to use h743 lqfp 208 for my application(ECG MACHINE WITH DISPLAY 1080*800-8.88") use of ETHERNETFMC for SDRAMQUADSPISDMMC1USB OTG FSLTDCUART, I2C and SPIis avoiding that h745or747 dual core is ok? 743 is itself enough right?.or is d...

Based on expert advice, for our first revision board, we've been editing the Altium files of the H753-EVL board. We replaced all BGA packages with QFN, especially the 208 MCU where footprint creation doesn't matter, and ensured that all I/O ports mat...

Are you suggesting that an I2C port extender can be used to add up to 20 extra GPIOs on the H753-EVL board? I see that it has an MFX, which stands for Multi-Function Extension ports. Is this what you were referring to?

jr_engr_mbed · 2024-05-07

yes, I got answer from you.,As you mentioned, it's acceptable to use Altium files, but with certain restrictions. If I change the package from its original BGA to LQFP, should I proceed with the same package for custom board replication of the STM32H...

Yes, it's a 1024x600 10.1" DWIN display with CTP, so it seems suitable. Currently, the layout person with many years of experience in design can handle any package. My role is to provide the necessary schematic documents. I tends to know after many d...
