Hi ,I am working on STM32L073 controller that talks to host over ethernet .Controller has no onboard ethernet port hence it uses spi interface to communicate with LAN9250 ethernet IC . In initial stage, i was able to transmit and recive packet(obser...
I am trying to use the STM32F103V as a keyboard and I have tried following online tutorials on this but when I check on Device Manager, I cannot find the device at all.Here is the tutorial I followed: https://controllerstech.com/how-to-use-stm32-as-a...
I'm currently trying to program the MCU using UART by entering bootloader using BOOT0 and nRST. However, whenever I send an nRST pulse PA12 gets pulled up and I'm not able to connect to the MCU. If I power cycle the board while BOOT0 is pulled high I...
Hi. I'm very familiar with STM32F1/STM32F3/STM32F4 families. I need to support 10/100 Ethernet for my project, but none I can't find any micro in stock (Mouser, Digikey) from the families I mentioned that supports Ethernet. Do you have any other reco...
I'm using a STM32F103 MCU in a project with micro SD card interface. The SD card is connected via SPI. When I use the STM32 SW, I can only connect to SD cards with a maximum capacity of 2GB.How can I support cards with up to 32GB capacity?
I am trying to set up ethernet on stm32h745iit6.I bare ethernet project from the H7 examples and use (low_level_output) func from ethernetif.cpp.I send buffer, located 0x24000008, where dma can access. And ethernet always send only init string of buf...
Hi all,I'm using STM32f048t6.I would like to load code using DFU bootloader for virgin device using HSI48.The boot configuration is correct using BOOT0 pin.Is it possible or I need an HSE?Note: after a jtag programming the USB works correctly. At har...
Hello,I am using the STM32L4R5ZI-P dev board.I have configured USB as a device only with the CDC class, where APP_TX_DATA_SIZE is 2048, USBD_MAX_STR_DESC_SIZ is 65536.When I am transmitting a data buffer of 512 bytes continuously for 1 millisecond th...
I am trying to use the UCPD peripheral on a STM32G4 (later on STM32G0) target to detect when a debug accessory device has been plugged into the USB-C port. This is going to be used in factory test.The issue I'm having is the dead battery pull downs a...
