STM32 MCUs Products

Hello!!! I'm working with the USB as a virtual com port of the STM32L4R5. If I'm not wrong, the size of the reception data is only 64 bytes and the transmissin buffer is limited to 2048 bytes. It's possible to increase both buffer size? Best regards,

Hii, I am new to stm32 and I am learning to program MCU using Registers. which STM32 should I go for for learning the basics like GPIOs, ADC, UART etc. Thanks in advance for help.

FDCAN2 FIFO Transmit ends up in FDCAN1 RX FIFO1. Is this a known issue?

I'm using HAL, and although there's a LOT of code, the gist is I transmit a message like so:HAL_FDCAN_AddMessageToTxFifoQ(hfdcan2, &tx_header, tx_data);and in the task for my hfdcan1 bus I sometimes get that same message when doingHAL_FDCAN_GetRxMess...

Hi Has anyone tested the BLE_MeshLightingPRFNode example present in the BLE Mesh V1.13.1 SDK anf ST BLE MESH app for Android?

I followed the LAB of the course on mesh networks and I am able to add the device to the mesh network. I use the ST BLE mesh App. The problem is that when I try to turn on the LED the application goes into a loop.

Does ST has or planning to have Ethos-U based Cortex-M Low-power Micro-controller for Wearable Applications?

HAL_FLASHEx_Erase Problem

Hello everyone !I am converting one of the my projects from F0 to G0. While debugging, when i come to HAL_FLASHEx_Erase line, it jumps to HardFault. I checked the memory, flash address is empty. I don't erase the program. Here is the some picture dur...

I2C2 as a SMBusDevice NACK?

firstly, i use stm32f103RBx as MCU. I2C2 set SMBusHost,the SMBusDevice set address 0x24, but the slave nack when smbhost send smbdevice address. the folllow is my timing:

What happens when the cortex core tries to access a memory location being written by dma?.

For example, lets say that I have an ADC configured in continuous single channel dma mode, writing to an array of 1 uint32. If the core tries to read that address while the dma is writing to it can it get incorrect values? or does the bus matrix arbi...

How can I call STM HAL UART code in multiple files?

I have a file in my VisualGDB project that has all the HAL code necessary to talk to a GPS receiver through a UART. I can #include this GPS file in one of the other files in my project and the code in that file can talk to the GPS just fine. If I #...
