STM32H563: No TRACECK present

Hi, I have configured my STM32H563AI CubeMX-project to use "JTAG with Trace  Synchro(4bits)" and assigned the corresponding pins. Also, I explicitly activated the corresponding registers in DBGMCU and DCB by adding: SET_BIT(DBGMCU->CR, DBGMCU_CR_TRA...

Behaviour of conflicting CAN filters

There are two situations where I'm unclear on how CAN filters would behave. 1. Direct ConflictOne filter says reject 0x0 to 0x123One filter says send 0x0 to 0x123 to FIFO0 2. Different behaviour for a subset of messagesOne filter says send 0x0 to 0x1...

STM32L073 operating on low power

Hi, I am working on a project where I have a custom board with STM32L073 MCU and I want to read a color sensor (AS7341) via I2C. This will be a low power application. I will harvest energy via NFC from a smartphone (I am using NTAG I2C plus). I can g...

Does NUCLEO-H755ZI-Q Support Ethernet?

Hi everyone,I'm using the NUCLEO-H755ZI-Q board and I’m a bit confused about its Ethernet support.The user manual (MB1363 Rev C) shows that both H745ZI-Q and H755ZI-Q support Ethernet using the LAN8742A PHY. It also lists jumpers and solder bridge se...

Unexpected RF emissions from STM32WBA55

Hello,I'm building a BLE receiver using an STM32WBA55CG.The device should only receive BLE advertising packets, never transmit, so I've put it in a "central" role. The device will be used very close to sensitive equipment, so it is very important tha...

Difference between STM32N657X0 and STM32H753XI

Can we use STM32N series high end crypto version in medical devices? Currently we are using H series from ST but we are facing some issue in CPU utilization and speed. Apart from external flash is there any major difference where N series is lagging ...
