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 STM32L052K6U6 to communicate with an SPI slave using the UART1 synchronous mode (configured with CubeMX, using the LL library).This is part of the code that receives data:while(!LL_USART_IsActiveFlag_TXE(USART1));LL_USART_TransmitD...
Does the STM32F7 supports the USART multi drop mode ?
i have a an stm32f417vgt6 mcu and its connected with ft800 through 30 cm SPI cable and the ft800 is driving a tft lcd .. the problem is when the mcu turn on or turn off the Contactor the mcu halt .. can you please help me how to detect the prob...
i want to build circuit that can measure AC voltage 0-600V AC using STM32 it there any sample circuit and example code of it..i have try some circuit ...1) 0-400v ac --> stepdown transformer --> 0-15v ac --> dc --> resistor divider --> adc pin MCU b...
Hi, everybody. My task is to connect STM32F4 discovery Board with Smart Card ISO7816. I don't use interface ST8024CDR only hooked paid directly by the scheme specified in the image:I tried to adapt the Cubex project to STM32F1xx-EVAL. ATR reception d...
I am trying to capture input from an external source. Using CubeMX as a guide, I configured timer 3 like this:/* TIM3 init function */ void MX_TIM3_Init(void) { // PC8 ------> TIM3_CH3 TIM_IC_InitTypeDef sConfigIC = {0}; GPIO_InitTypeDef GPIO_...
Dear AllI am playing with TIM 1 to better understand its functionalities. My tests indicate that in the toggle mode (set through OCxM bits of CCMR): 1) The counter operates in the up-down mode, even if the CMS bits of CR1 are set to 00 (which is for ...
Hello! I wanted to know how inaccurate the RTC is when working with LSI or LSE.Reading from posts and data sheet of the MCU, I saw that LSI is much more imprecise than the LSE. I wanted to know if there was an equation that would allow me to estimate...
Hi friends,I have DMA2 moving data between a look-up-table to GPIOB. DMA is fired by TIM8 that generates constant sampling time.The system works fine, but when main loop have some instructions (dummy instructions that doesn't affect DMA system), DMA ...
Dear Members,I changed my clock from MSI to HSI but my SPI and UART baudrate becoming wrong,What do I miss here ?thanks
