Hello, working with STM32H742, I need 480 MHz in some parts of my code while on the other hand I need to save energy. That's why I came to think about changing D1CPRE and HPRE between (1, 8) and (8, 1) to (maximize , lower) sysclk while keeping the ...
I know how to write to notification attribute (with aci_gatt_update_char_value).How do I response to READ attribute?Thanks,Lior Malik
Hi, I am trying to use the external SD Ram(8MB) of STM32F746 DISCOVERY board but the program crashes after writing 16kB of data . I am new to STM32 platform, I first generated the initial code with CubeMX ide and configured the ram as per the exampl...
I purchased the stm32373c-eval board. After downloading the demonstration firmware STSW-STM32114 https://my.st.com/content/my_st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32-standard-peripheral-library-exp...
Оne injected channel + DMA ?
Hi, I am using the STM32G071KBU6N. It has the BOOT0 and SWCLK (PA14) on the same pin. Defined the pin as SWCLK in STM32CubeMX. So I assume that the SYS registers are set right in the software generation. However after the first download of the first ...
Hello,I have received conflicting answers to this question so I want to try asking it in a different way. Hopefully you understand my situation but please let me know if I should clarify anything.I want to use an STM32G431RB. I need to be able to rea...
Hello, I am trying to use an ADC (AD7124) which is communicating through SPI with the MCU.Previously, I managed to run the ADC with STM32F4. For this I used the libraries provided by the ADC manufacturer. While the ADC is running prefectly with STM32...
Dear all,The MCU : STM32F051R8T on Discovery BoardIssue : USART1 and USART2 are required. The clock of USART1 can be configured by CubeMX. However, it is not possible for that of USART2DetailsThe clock source of USART1 ...
Hi, I'm using stm32f030cct6 and control the sx1276.I configured SPI1 like thatvoid SPI1_Init(void){ SPI_InitTypeDef SPI_InitStructure; GPIO_InitTypeDef GPIO_InitStructure; RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA | RCC_AHBPeriph_GPIOB, ENABLE); R...
