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...
Can you explain how to play wav file using internal DAC and how to set the frequency for wav file using timer.Since I am a beginner any help from you guys will be a great boon for me guys
Hi,RCC->APB1ENR |= RCC_APB1ENR_I2C2EN;immeditly after turning on the I2C2 Clock I get a busy flag for I2C2.Its then reset with:GPIOF->MODER |= GPIO_MODER_MODER0_1 | GPIO_MODER_MODER1_1;But when PUPDR is executed, the flag is busy again:GPIOF->PUPDR &...
The intend is to detect whether an array (size 256 bytes) is present in RAM at a location pointed to, and does not trap a HARDFAULT when the pointer written to it. A subsequent read from the same location should produce a value different from the val...
I have array[2000];I am trying to send from nucleo to arduino, it seems if I send bigger than 8 elements it freezes or does nothing. So I have no problem to send array of 8 elements.I know that I could do it piece by piece in a for loop, I would have...
hello I have a structure arraytypedef struct { uint8_t Line_Add[lcd_lines]; char Line_Data [banks] [lcd_lines] [40]; uint8_t Data_Pos [lcd_lines]; uint8_t Start_Pos [lcd_lines]; ...
I would like to upload a project built with cmake gui in the Window10 to mcu board based on stm32f427II chip. When I build cmake, configure is configured as VS2017, and the result is as shown below. However, to upload to the board, I think I need to ...
Hi, I have a strange behavior with the RTC alarm only with some MCU. In my project use the STM32L476, when I set the alarm the MCU wake up without problem, but this work fine only with some board. On the other boards with the same MCU and the same FW...
I'm trying to use interrupts for SPI, but am a little lost. I see the Transmit_IT function in the HAL library, but I'm not certain how to use it in a non-blocking state. Is there an example on how to use it?
Posted on January 09, 2016 at 20:34Hello.I recently started testing the communication over I2C on a NUCLEO-L476RG board using the HAL API.Looking through the reference manual (http://www.st.com/st-web-ui/static/active/en/resource/technical/document/...
