Hi dear friendsI am controlling a current source DC-DC converter using a stm32g474 microcontroller. I am using all 6 HRTIMs to generate 12 PWM signals for my 12 switches. My converter has different operation modes and in each one, these 12 timers hav...
Hi STM team, We are using the stm32L476ZET6 microcontroller and developed our custom-embedded device, which operates on the backup battery (4.4V) as well as on an external constant DC (12V) supply. So far, we got good results for our business use...
hello everyoneUsing the internal ADC(polling method) of the stm32f429 board the samples that im getting are too many for one cycle of analog inputhow to reduce the samples without giving a delay, like if I want 128 samples for one cycle.Vin is 300mVA...
Hello, I want to convert the ADC value into voltage. Using internal ADC1 in stm32f429-disc1 boardThe input voltage applied to channel 1 is 300mVAPB2 is 90MHZClock Prescaler is PCLK2 divided by 4Resolution is 12bit(15 clock cycle)Sampling time 3 cycle...
Hi,I managed to successfully incorporate a webserver into our project with the following details:- STM32H753- Azure RTOS + NetX- 32Mb QSPI NOR flash (8Mb for webserver purpose, 8Mb for File system, some part will be for product use)- provision for SD...
Hi, I am having problems connecting my f429 board (nucleo 144) through ethernet with TCP. I followed several threads that i lost the link to, but here are my settings. and of course the LWIP configuration (everything not shown was left by default)i a...
Hello. Try to start ETH on STM32H733. ETH_DMAMR_SWR setted by HAL in HAL_ETH_Init() but do not reset by device during timeout 500ms and even 2000ms. The same code run over STM32H723 perfect. I am try this https://community.st.com/s/question/0D53W0000...
Hi everyone!I'm experiencing on ethernet communications using a NUCLEO-H755 board.I already configured the LWIP stack on the M4 core and it seems work.Now I'm trying to make it work on the M7 core following this guide:https://community.st.com/t5/stm3...
I'm trying to build a Custom HID project to mimic a certain device. I've prepared the description bytes packages and everything is working fine as long as I continuously send data. When I stop sending, device goes to LP and SUSPEND mode. I couldn't f...
We use STM32CubeMX and STM32U5. STM32U5 supports linked list DMA transfers. But HAL_ADC_Start_DMA() will not do a transfer larger than 64k. It only creates the first element in the list and exits. In addition, HAL_ADC_Start_DMA() doesn't give a...
