STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I've built a new prototype using the STM32U575C, and provisioned two program/debug connectors, a fine pitch Samtec header and 0,1" pitch six pin header, I've used both before on STM32F4.I've tried accessing the processor using both headers, an STLINK...
The project code for my Nucleo-H563ZI sent an I3C Broadcast sequence for dynamic addressing. I can see the Broad cast sequence on the analyzer. There currently is NO I3C Target on to answer, yet the analyzer does show a NACK after RnW(1). I believe t...
I'm trying to initialize an LCD module (ST7796U controller) on a STM32F103VET6 development board using SPI1, yet the souce code I got from the seller is using software-simulated SPI instead of hardware SPI (with SPI1_NSS enabled as output): #define...
everything is working, downloads and runs, I am still not sure it the external QSPI works.I can write and read from QSPI, checked but I am not sure if it works as external flash to load the code and run from it.I chose to put main.c in external flash...
Hello,Greetings to all community members, This post is regarding USB enumeration in STM32H7 series. I am currently using MCU STM32H747XIH6 for one my project in which I am configuring this MCU in USB Host by using USB_OTG feature available in it. I a...
Hi everyone,As commented in the title, in our system we have two ways of working. At low speed (120MHz) and at high speed (480MHz). When reading the ADC3 (temperature sensor) depending on the mode (low or high speed) I get different values. When I wo...
When using the STM32H750VBT6, I supplied around 1.37-1.4 supply voltage to the external pins VCAP1 and VCAP2,the project was configured as an external power supply using cubemx software.HAL_PWREx_ConfigSupply(PWR_EXTERNAL_SOURCE_SUPPLY); is used in t...
Hi, I am using the B-U585I-IOT20A Board and I want the board to notify me in some way if someone is attempting to access and modify its content via JTAG. Is there a way to do this?
I designed a circuit board with the STM32f765vgt6 chip following ST's hardware recommendations (two 2.2uF ceramic capacitors with low ESR connected to Vcap1, Vcap2).I'm having the following issues: When I initialize the CPU clock frequency to 216MHz,...
Hello,I'm managing a Wifi modem using one of the USARTs of the STM32L475.Modem is working fine when sending and receiving AT commands and data, but I'm not able to receive URC's.I only receive URC's when they come 'together' (very close) to the answe...
