Hi ST team,I was coding on STM32L431 chip and got a problem about the RTC time.The problem is that the RTC time is not synchronized with my input randomly after the MCU is waked up from Standby mode. The following descriptions are the detail.[Reprodu...
Posted on November 10, 2013 at 07:51Is it possible to decode a mpeg4 file in stm32f407 .at least 15 fps & 320x240 pixels.till now i can decode jpeg pics quite fast . if its possible is there any open source library to do this?i have looked at ffmpe...
Hi,I'm currently developing an application on a STM32F103 MCU that is capable of upgrading its own firmware over CAN. The flash memory is split into 2 partitions and the when the currently active application receives a FW update it copies it into the...
Hi AllI have been experimenting with setting flash sector write protection but found that when I did I could no longer program with the debugger. I managed to reset the options by writing the unlock sequence via the debugger (that can still connect) ...
Dear all,I'm using the STEVAL-PCC009V2 based on a STM32F103RBT6 microcontroller, set to work with an internal clock frequency equal to 72 MHz so CK_INT = 72 MHz (refer to figure 100 of RM0008 Rev. 19, pag. 367/1132).I need to obtain a 10 ms time base...
I have basic understanding about buses, but this term is new to me.What's bus turnaround phase - and measured from where to where?Google hasn't been my friend on this.
Hi All, My environment: STM32L151CB, SPI2 Master, DMA1 Chan4(RX) and Chan5(TX)I moved from HAL to LL (to save memory) and faced with the following issue:When I configure SPI to receive data by DMA and setup only RX DMA channel SPI transaction doesn't...
Hello,I built a test app that writes data in files on SD cards in a freeRTOS enviromnent in order to testCube (and cubeMx) librairies 'integration.I wrote a task that write data on one file, then another and so on, the file prefix is the (data) of th...
Hi,I am working on custom design using stm32h743zi with ad9269 16bit 20MSPS ADC. Since I am a newbie for this kind of design and I needed to consider all the analog & digital part at the early stage of design, I just simply connected the adc outputs...
Hi, everyone.I want to connect a STM32L475RG board with an extended board, more exactlyS2868A1, which comunicated on SPI protocol. More that, i want to connect these 2 components with another Stm32L4 and S2868a1, and comunicate with them via S2-LP mo...
