Hello,I'm looking for detailed tutorials or lessons on the STM32H7S3L8 / STM32H7R3L8 MCU. Is it possible to purchase such tutorials or lessons? I've been using Microsoft Visual Studio with VisualGDB for quite some time now, but those MCUs are relativ...
How to cancel HAL_SPI_TransmitReceive_DMAWe are developing SPI communication devices using HAL_SPI_TransmitReceive_DMA.We would like to cancel or stop HAL_SPI_TransmitReceive_DMA even in the middle of transmission by GPIO interrupt, but we do not kno...
Posted on December 27, 2017 at 10:13STEVAL-IHP005V1 application software doesn't work???Hi all,I tried to install software for testing Power line module based on ST7540 and STM32.I installed it on window 7 and window 10, both of them can't start pro...
Hi all I am trying to run CAN communication (normal mode ) from my discovery board (STM32F407) to USB CAN analyzer via (TJA1050).I am able to see data on TJA1050 (CAN TX and RX side ) but no data is reflecting on CAN high and CAN low side, so because...
Hi Working on a project in which I require USART1,USART2 for serial communication.(RS485.)I am using processor STM32L053R8.the clock used is HSI.Timer21 interrupt is being used to measure clock period. (to test the CPU Clock).if the communication is ...
I have a Nucleo-F446RE and C031C6. The default code that came on the board uses the blue button to change the LED blink pattern... Is this code available? It would be very helpful to be able to see how it works.Thanks!!
I am trying to design a dev board using stm32 mcu but the issue is I cannot select a ferrite bead I know some basics of ferrite bead but what should I consider from my mcu’s side to select a ferrite bead for it can anyone help me about this or is the...
I'm trying to set up CAN in the Nucleo STM32H723 eval kit, I can see the message written to the CAN RAM, but I dont see any activity on the TX pin using an oscilloscope. The CAN is configured in NORMAL_MODE, I have testes before with EXTERNAL_LOOPBAC...
We are developing using STM32H743.We want to set 100MHz for SPI1 CLK and 117kHz for SPI2,3. However, we cannot set it because of "clock tree" and "maximum divisible limit is 256".Is there any way to achieve the above configuration?
About SCLK frequency for SPI communicationWe are trying to set 40MHz for SCLK.What is the maximum SCLK frequency we can set?Is there an upper limit depending on the microcontroller?
