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...
I hope the title tells it but F746 was out of stock in a couple of European stockists and H750 was in stock and also cheaper. Both in LQFP100. I wonder am I lucky or do I have to make a new board? If buggy forum permits, that is.
I have the following EXTI9_5 handler: (yes, with HAL)void EXTI9_5_IRQHandler(void) { if (__HAL_GPIO_EXTI_GET_IT(GPIO_PIN_6) != 0) { __HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIN_6); return; } if (__HAL_GPIO_EXTI_GET_IT(GPIO_PIN_5) !...
I'm currently in the process of compiling example code from our supplier for an e-ink display. The issue however is it uses functions that predate HAL from what I can tell. While some things are simply renaming to uppercase, some other things are unk...
Hello,I am working with STM32F407 evaluation board. I want to use i2c as a slave on it.My master device is siliconlab micro-controller (mighty gecko).What slave address i should use for sending data for STM32?As master needs slave address to send dat...
I'm trying to use ADC in stm32g030j6m6 to measure DC voltage.but, whenever I try to make experiences. I found out that under 3V, The accuracy of adc isn't great. It has a 10% error.I attached source code that I used in my experience and the table th...
External oscillator: MC-146 32.7780KA-A0Load capacitors used: CL_1 = CL_2 = 8pFWith Drive Level of Low the application works. I would like to obtain better understanding of how the G_m_crit_max is connected to the CL. I've had a look at AN2867 - Osc...
hello, i have a input capture who lost edge when i plug USB.when the USB cable is not plug or unpluged works perfectly.i have a toggle led in the capture callback.when i plug the frequency of the led is unstable.when i unlug cable, toggle frequency ...
Hi,Iam using STM32F103RDT6 for my project. A 12MHz external crystal is used for the same. In the datasheet it shows REXT is needed.1.What is the purpose of REXT? 2.Is it required mandatory? Because in my board iam not using the same. So I want to kno...
I'm having trouble reading the temperature, its values are incorrect. The temperature in the room is 22C and the temperature of the sensor shows 55C (selfheating and the measurement error cannot be that big). I have many times checked the correctness...
