STM32F4 / STM32H7 RTC HW BUG - Shadow registers for seconds and subseconds are inconsistent
Hi. I found a bug in RTC shadow registers inconsistency of seconds and subseconds.Subseconds are counted from PREDIV_S down to 0. Then the seconds are incremented and subseconds start again from PREDIV_S.Sometimes subseconds contain PREDIV_S value an...
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.
Resolved! STM32G0B0KE Input voltage range when using Vrefint
I'm trying to decide what G0 STM32 part to use on a brand new design. One of the requirements is to have six channels of ADC. The datasheet talks about the range of input voltage being Vssa <= Vin <= Vref+. However, on the 32-pin part, there is no Vr...

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:
