Can I use the NUCLEO-F767ZI in a commercial product?
I'm pretty deep into my design already but when i was looking for a schematic the other day I stumbled upon the EVALUATION BOARD TERMS OF USE. The legal speak there is pretty confusing, but I see nothing on the ST website that defines the NUCLEO-F767...
Accessing multiple wiznet modules using address bus decoding and single FMC SRAM nterface.
I have a requirement to interface 8 numbers of Wiznet Modules (Wiz830MJ) with STM32L496. Since i need to interface more than 4 modules so i cannot manage with standard FMC SRAM interface. So I am planning to use a decoder (74HC138D) and generate 8 di...
Voltage Digital PIN
Hi, I have a Nucleo 144 STM32H743ZI2 and I try to convert 3.3v to 5v with level converter to send signal to a driver. I bought a Level Converter MH but when I measure the high voltage, marks 2.5V and in the low voltage 3.2v. I tried putting 3.3v from...
Will there be different typesetting for ST 32-bit MCU body screen printing of the same model? Will there be different screen printing layouts due to different origin, packaging and environmental materials.
The typesetting of the second picture is inconsistent with that of the datesheet, does it exist? In addition, what is the meaning of E3 and E4, and what is the meaning of "X"
Resolved! ST-Link Utility - The elf loader file is not accessible
Hi,I'm trying to program a 32-bit STM32 Cortex-m4 MCU (specifically STM32L4P5ZGT6P).I'm using v 4.6.0 of ST-Link Utility, and I've tried both an ST-Link V2, and an ST-link V3, both with latest firmware.Both succeed at connecting (reading) the MCU, bu...
STM32F051C8: High current draw from VBAT when VDD is on
I have a minimal prototype circuit (breadboard actually) with this schematic: The firmware initializes a few peripherals (including the RTC) and enters an infinite loop calling __WFI(). Nothing else happens and nothing else outside the BOOT0 pulldown...
Resolved! Cant debug my own board with a STM32F303VB MCU - how to resolve this issue?
Hi,I just powered up my own board and i just wanted to start debuging.The first thing i tried was to connect with the STM32 ST-Link Utility and an ST-Link V2.This works fine. I can connect via SWD and can read the Chip-ID and see the Flash.In terms o...
