We have STM32F405RGT6 and we want to implement DAC through DMA.We used an example for STM32F429ZI-NucleoHere is an actual code where we have an underrun the error and we need help to clarify reason and find a solution, thanks!: #include "main.h" #i...
I've been over and over RM0433 regarding how to set this mode up and I've never been able to get data from ADC2. ADC1 acts a bit oddly in that my reading says that 16 bit ADC results from both ADC1 and ADC2 are packed together in one uint32_t locatio...
Hi,Does anyone know if there is a chance for a new N6-device later this year having built in flash of at least 4MB?Our project is currently based on a one chip solution with a custom U5-board with built in FLASH/RAM of 4MB and a 5” Riverdi display. H...
Hi,I am using an STM32H7RS MCU (NUCLEO-H7S3L8) and I need to use both USB HS Device and Ethernet MAC.For Ethernet MAC I will only need to use MDIO interface, so I don't think I need a stack for it but please correct me if I am wrong.The MX_ETH_Init c...
Posted on October 23, 2017 at 12:33Hello,I've tried the I2C_TwoBoard_RestartComIT example in the STM32Cube_FW_L4_V1.9.0. It works fine.If I disable the clock stretching feature, the slave can still receive messages, but it doesn't transmit back. It ...
usart1 connectedHercules setup utility Issue with Sending Bootloader Command on STM32According to AN3155, the 0x7F command should initialize the USART. I have ensured that I am in bootloader mode and have made the following connections:Connect th...
Hi, Greetings!! We have implemented internal DAC (DAC1 and DAC2 both) in STM32F446RE chip. Both the DAC gives identical analog voltage from the range of 0-1V corresponding to the measurement reading of 0-100. This analog output voltage is connected ...
Hi, I am using the STM32F429ZI board. I enabled the hardware-independent watchdog timer using STM32CubeProgrammer option bytes. However, there are no errors or faults in my project—I have only enabled the GPIO and UART peripherals. But after enabling...
Hello STM support, It seems that the depiction of the TIM15 TPCLK on the clock configuration tab of STM32Cube incorrectly shows TPCLK as 2x16MHz=32MHz when should be 16MHz, same as PCLK.I found this issue after setting TIM15 as shown in the attached ...
Hello, I use 25 MHz quarz (XRCGB25M000FAN00R0) together with 5.6 pF load capacitors. When I configure clock to 170MHz my program stuck here: while (READ_BIT(RCC->CR, RCC_CR_PLLRDY) == 0U). When I configure clock to 168.75 MHz, then everything work co...
