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...
1. It is correct to read and write flash through command function when there is no memory mapping enabled（ flash:MX25R6435F ）2. After memory mapping is enabled, after accessing the address of 0x90000000, the MCU crashes and cannot recognize the chip....
I can not debug STM32L552 Nucleo-144 board with STM32CubeIDE 1.16.1Here is output message from IDE:STMicroelectronics ST-LINK GDB server. Version 5.8.0Copyright (c) 2020, STMicroelectronics. All rights reserved.Starting server with the following opti...
Based on the info in the STM32 reference manual, I would have thought this code to start up the WWDG would work (after processor reset). // sets up the WWDG with a period of about 1 sec, no lower limit inline void StartWwdg() { LL_APB1_GRP1_EnableC...
Hi together,I have ADC reading issues with my STM32G431. I read the ADC with DMA. The readings are triggered by a burst of pulses (approx. 750 kHz) and the ADC buffer seems to get filled. However, the ADC readings are way to high.A 2.5 voltage regula...
Hello,I am trying to recognize a number sent to USART:If I send '123' over USART to MCU then MCU receives only '3' (the last character). Variable recv has uint8_t (unsigned integer) type. How could I receive the complete number ('123')?I am using STM...
Hai,I just want to enable the gpio through the LabVIEW using VISA communication, for this how can i make changes in stm32 firmware code to enable the gpio through the labview, if anyone have idea about to how to write the firmware code to access the...
The description of DMA_CMARx (and also DMA_CPARx) register in single-port DMA (AN2548) says:This register must not be written when the channel is enabled.What wrong may happen if this register is written when the channel is enabled?This of course is ...
Hi,I'm trying to sample data inside an ISR, write it to a buffer, and then write the data in the buffer to an SD card. The SD interface uses the SDMMC devices.It seems that when the ISR interrupts the SDMMC performing a write, the SDMMC errors and re...
i am using NUCLEO-G474RE board, TIM1 to output PWM wave, it works fine ,i can see the pwm wave through scope, but when i use HAL_TIM_PWM_Stop(&htim1, TIM_CHANNEL_3);HAL_TIMEx_PWMN_Stop(&htim1, TIM_CHANNEL_3);to stop PWM , there is a attenuated wavefo...
