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...
Hello,i am using a Nucleo - F411RE board and i want to create a sine wave with an external DAC (mcp4922). So i initialized a SPI connection to send my sine wave table to the external DAC. The frequency of the ouput sine wave should have 40 KHz. At ...
Hello Forum,I am new to STM32 but familiar with MCUs. My Problem is the SPI interface.In the datasheet there is a figure (figure 277 of document RM0091) where all four possible combination of CPOL/CPHA are shown. There is also the signal nss in the f...
1. Array of bytes? Read and write between CPUs.2. Peripheral allocations to CPU1 or CPU2? Should allocation of peripherals handled by only one CPU? What will happen if both CPU's are asking for same peripheral. How to handle this scenario.
Am facing problem while receiving file from PC as YMODEM protocol, Am just using ymodem.c an d ymodem.h file fromIAP library i have modified the code, but am not receiving Header packet only(SOH or STX), please help as soon as possible am struck here...
Hi Guys,I am newbie to STM32 family. I am currently building an application to collect ADC sensor data and operate a motor using PWM signal. I used example code to play around with it. I initialized ADC , configured the channel, and calibrated befor...
After successful test on STM32f401RE I moved my design on STM32F071 for cost reasons.I am using UART1 and UART3 first set to 9600 and second set to 115200.But on PC I can see the data only if it is set to 4800 and 57600.At the beginning used interna...
what is the role of voltage regulator in stm32f407vgt6 and how it works..that means already VDD is supplyng 1.8V and again what is the need of suplying 1.2V and how it works i want to know exact operation of it in stm32f407vgt6
Hellow.Mr.Kang system engineer in South Korea.Looking an ADC high performance STM32.The specification is as follows:1~5Msps , 2channel, PGA (if possible)
Hello, I would like to use #define macro in my program to hold application, firmware version and firmware building time. I know i can put these definition into my program directly, and make modification before I compile my program. Could I use GNU C ...
