Error in the init of ethernet
Good morning everyone!I'm working on a project involving FreeRTOS, lwip, and Ethernet with the ST32H563VGT6 MCU on a custom PCB.I'm attaching the hardware schematics, which we've taken from ST's schematics of the NUCLEO-H563ZI board. I'm including a...
Resolved! internal resistance ADC
Good morning. I am working with the Discovery kit with STM32H7B3LI MCU and want to get its internal resistance. I want to use 10 buttons, each with one resistance, and then get the correct value for my MCU. I already know how to get the values betwee...
Query: STM32F4 programming with USB
I can program my bespoke board using a repurposed USB port. It would normally be used by a mouse.I was under the impression that if I powered up the board with BOOT0 pin held high the MCU would be in a state to connect to USB and do it's enumeration....
Resolved! RTC Wake-up Callback Not Working and IWDG Reset in Standby Mode
Hello, I am working with STM32G030K8T6 microcontroller and I am using an independent watchdog (IWDG). The device goes into standby mode under certain conditions, but since I cannot turn off the IWDG, I am trying to reset the IWDG by waking up with R...
Resolved! STM32F756 Ethernet and lwIP LWIP_RAM_HEAP_POINTER
I am using the latest version of CubeIDE (1.17.0), a STM32F765 Nucleo board with Ethernet. I am configuring the project to run lwIP using the internal Ethernet MAC. I am using FreeRTOS (CMSIS V2). CubeMX configures this LWIP_RAM_HEAP_POINTER to a def...
STM32H743 SDRAM issues with LTDC + DMA2D
Hello,I'm trying to use a STM32H743XI to run a 1280x800px LCD display. I'm using an external 32bit SDRAM (IS42S32200L) running at 110MHz.The active framebuffer (RGB565) is located in the first SDRAM bank and I can display a stable image with LTDC clo...
Resolved! STM32F411RE I2C Write/Read an External EEPROM Memory 24LC1025
Hello community :)I need help using the EEPROM Memory 24LC1025.I've this address for the 24LC1025 EEPROM ( A0 = 0, A1 = 0 and A2 = 1). And I'm trying to write/read on the data address range 10000h-1FFFFh but I'm not able to, when I try to do anything...
Resolved! Fast FLASH programming - mass erase neccesary?
I read in the doc for the G431:"The Flash main memory programming sequence in standard mode is as follows:1. Perform a mass erase. If not, PGSERR is set."So i can not do a single page erase??
SPI DMA is not workng at higher SPI baud rates
Hi,My NUCLEO-H563ZI application uses SPI with DMA. The SPI transactions are not working at clock/2 clock/4 and clock/8 rates, clock being 250 Mhz. Is there any clock frequency restriction when SPI is used with DMA?
