Can I run the X-NUCLEO-IHM07M1 motor driver using an STM32F767ZI development board?

X-NUCLEO-IHM07M1 is compatible with STM32 Nucleo boards and is already in use, but I want to know that can I use STM32F767ZI development board which is also a STM32 Nucleo board but is a Nucleo-144 board to run the X-NUCLEO-IHM07M1 motor driver is no...

Hello everyone, I am trying to code for multichannel ADC in STM32F103RB. I have 9 analog inputs. I am using polling method to get values. The values get shifted when i read the adc values. Please help me find my mistake.

I have configured 9 channels as follows:- channel 5,8,9,10,11,12,13,14,15. Now Sampling time for all channels is ADC_SAMPLETIME_1CYCLE_5. I have attached potentiometer for as input voltage. Now when I change pot of channel 9, it gets reflected in cha...

What is the minimum RAM requirement to create Image animation using touchgfx designer?

Hello,In our custom board we are using STM32F429VG controller. Which has internal RAM of 256K. I want to creating a screen with some animation using touchgfx designer. In that animation I want to create 3 circular rings each ring will contain 40 dots...

VDD is unstable. because of VBAT??

Hi there.I'm using a STM32F071 series.I want to use a RTC with power backup.So, I added a super-cap on VBAT.​when I power off and on again, ​VDD becames a saw blade.... what???After I discharged the super-capacitor and power on again, VDD is good.I t...

ADC measuring internal reference gives strange results for shorter sample times. Is there a way to measure the internal reference with sample times of 1.5?

Setup: 48MHz CPU clock, ADC clock = CPU/4. For various sample times, I get internal reference measurements of: 1.5 - 1925, 7.5 - 1760, 13.5 - 1420, all other sample times give 1550. I thought sample times were to cope with high impedance sources. ...

STM32L476RG using internal PGAs with ADC in differential mode

Hi,I am using the STM32L4 ADC in differential mode (PC0 and PC1), to capture the dual end output of a tuner which provide a 600 to 800KHz signal. The tuner maximum output is 2.0V PP, and the STM32L4 differential input is rated for 6.6V PP (-3.3V to +...

Hello , I want MAC ID for STM32. How to get that? To whom I should contact regarding this?

how to use extern "C"

hi everyone want to use interrupt in main.c i am using extern "C" for this purpose but its couldn't compile/* USER CODE BEGIN 4 */ extern "C" void TIM2_IRQHandler(void) { // Handle update interrupts (update interrupt flag is set) if (TIM2->SR & TIM_S...

High delay of Timer triggered ADC conversion: should I enable ADC?

Hi everyone,I'm trying to perform some ADC conversions triggered on a timer rising edge, this timer can be up to 1MHz.I set up everything in cubeMX and can perform those conversions, but the delay is too high for my application.My current problem is ...

in stm32h7, access to battery backup ram inside stm chip sometimes doesnt work. on nucleo board. when clk turned on, battery ram stops working. thanks

battery backup ram works after power on. stops working ( get hard fault ) upon access to variable in battery backup ram. battery backup ram works when developement system dissconnected. sporadicaly stops working when ijet or segger connected to nu...
