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 have a strange problem. I have a global uint32_t variable that counts up in the main loop and every 100 ms it gets reset in a timer-ISR. This works, but sometimes it does not.Here is the value of the variable MainCounter read out by the debugger:Th...
Hai allWhen I use HAL_ADC_Start_DMA(&hadc, ADC_RES, 160); this function .How to enable ADC interupt bit .I want to Trigger void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef* hadc){ HAL_GPIO_TogglePin(GPIOC, GPIO_PIN_6);}this funtion How to enable it wh...
Hi,I want to use PB3 an PB4 pins as SPI1. When i use st-link and debug my code, it works. but when i plug-off st-link it seems that mcu can not boot. I use the codes below for jtag disable , but it does not work. Any advise for my problem? GPIO_InitT...
I trying to program a nucleo-144 L496GZ-P board which has been split from the st-link. I've connected the SWD pins as instructed in the user manual (SWD1 -> 3v3, SWD2 -> SWCLK (CN11 P15), SWD3 -> ground, SWD4 -> SWDIO (CN11 P13), SWD5 -> NRST (CN11 P...
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...
