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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
HiI'm just trying to run a simple DAC program using the DMA but its not working. The details are as follows:signed 16bit int lookup table with the size of 128using timer 2 trigger out event for DAC DMADAC on OUT1 (PA4 pin) and DMA stream 5 selected o...
Hi, when I try to use pin #7 of STM32G031J6 as GPIO A14 configured as input with external interrupt, the debugger crashes and lose control of the application. This is not happening if I change pin, eg. use GPIO B0 on pin #5 the same way.Has anybody e...
Hi Everyone!Last few days I start to learn about Timer, especially about Timer with interrupt. I have a question about this. When I start timer, the interrupt immediately occurred and then after every 3 seconds.Is there any possibility to skip the fi...
Hi,I need to do a project where the mcu has to be flashed by an usb pendrive. Some time ago I think I read that the mcu STM32F1xx family has this feature, but I don't found now.It's the STM32F1xx correct or anyone knows about other mcu capable of doi...
This is my code to generate the value of the lookup table? Why timer 6 is never running on the code and I get this warning: HAL_TIM_PeriodElapsedCallback defined but not usedBelow you can see the code:/* USER CODE BEGIN Header */ /** **************...
Based on my powerfactor i can control only single fan. If i want to use mutliple fan of different i was not able to do. Then i searched in google they used EEPROM and flash method. But i did not understand it. Actually i need to select one digit...
I will be using STM32F4 CPU in custom boards. The PCB will be space constrained and I plan on using STMX&IDE for development debug/programming devices. So is there a need for JTAG interface (10 pin) or can I get away with just having the SWD header?
I'm working on PCB with two MCUs, and I'm not sure how to connect power supply lines. Even after reading the datasheet and RM0433, I still find it confusing. Like, which one of the VDD33USB or VDD50USB should I connect and why? Do I connect both? Or ...
I would like to be able to detect when the virtual com port gets opened by some program and when it closes the port.How would I do that?
