Resolved! STM32H563 clock at 250Mhz
I was trying to get the most out of my H563 set up and run as fast as possible. I am using the Nucleo-H563 board. I reconfigured in CubeMX to use System clock mux to use HSE source mux, multipliers and dividers set correctly for 250MHZ operation. The...
Resolved! Interfacing 32-bit SDRAM with STM32H750XBH6
Hello ST Support Team, I’m currently designing a custom board using STM32H750XBH6.In this design, I would like to interface a 32-bit SDRAM for improved memory bandwidth and performance. However, I noticed that in the official STM32H750 development bo...
STM32N6 it's possible to change XSPI2 to XSPI1 for boot using OTP bits ?
Hello,I want to change for boot to use XSPI1 interface, but I am not sure about OTP bits, there in description some bits is not very clear, what OTP bits to set to switch if it's possible ?Additionally if I will use SD card for boot I can set OTP11 v...
Has anyone else struggled with the MX3080/M1400 Wi‑Fi modules?
Honestly, this choice feels like a trap.STM keeps promoting it as a “solution,” but compared to Murata, ESP32, or Broadcom it looks outdated:– Legacy M4 core, original MXCHIP code from 2017– Closed software, very little documentation– Hard to debug (...
Resolved! STM32C071 unique ID - what are the first 4 bytes really?
I have a NUCLEO-C071RB with an STM32C071RB. In section 31.1 of RM0490 Rev 5, it describes the first 32 bits of the unique ID like this:Bits 31:0 UID[31:0]: X and Y coordinates on the wafer expressed in BCD formatBCD should mean binary-coded decimal,...
Resolved! Inquiry about- DCMI of STM32U595RJT6Q
Good Evening Sir/Mam, Sir/Mam, I have a query about the DCMI of STM32U595RJT6Q. I have read the Datasheet of STM32U595xxx and it was written in it that- DCMI of this MCU is for use with Black & White Camera Modules and it is assumed that all preproce...
Resolved! STM32H533RET6 – Should VSSA be directly connected to GND or via an inductor?
Hi everyone,I’m currently designing a board using an STM32H533RET6 and I have a question regarding the VSSA pin connection.Should VSSA be tied directly to GND (VSS) like the other ground pins, or should there be an inductor (L) placed between VSSA an...
Resolved! USB available on STM32G0B0KET6 ?
DS13565 Rev 2 says under 3.20: "The embedded USB controller cannot be used on STM32G0B0KE as this device does not provide an HSE oscillator input.". Well, sounds reasonable. But same DS says in Table 11 for Pin 2 (LQFP32) PC14: "OSC32_IN, OSC_IN" whe...
STM32H755 ADC1_IN9 (PB0) reads ~3°C lower than all other identical NTC circuits
Hi everyone, I'm using an STM32H755 microcontroller to read 20 temperature sensors (NTC thermistors) via 20 ADC channels for a testing setup. Each thermistor is wired in a simple voltage divider circuit like this: [VCC] -- [NTC] --+-- [Fixed Resistor...
