Regarding the KNX TP, I tested the STKNX evaluation board and my board which have ST-KNX chip then have below questions: Q1, The testing connection is UART TX => KNX_TX (STKNX EV1) => KNX_TP line => KNX_RX(STKNX chip board 2) => UART RXCH1: KNX...
I have not seen displays with 1 data Lane MIPI but they are always 2 data Lane MIPIbut some STM chips have only one 1 data Lane MIPICan it be somehow connected like grounding the remaining line.
Good Day and Hello Everyone. In my upcoming project, my task is to upgrade the currently used MCU from STM32F103ZG to STM32H755ZI. My question are;1- Can I replace all the FSMC I/O pins that I'm currently using on STM32F103ZG with the FMC I/O pins on...
Hi, I've just got the STM32H723ZG Nucleo board and I'm trying to set up a High-Speed 480mbps data transmission. Do I need to buy an external PHY or does the model already support High-Speed USB communication?
Hi,Master:platform: STM32G070CBQuesion: Regarding CMOS - and TTL compliant, the manual provides the above diagram. How does it achieve compatibility? When Vin>min (07 x VDDIO, 2), is it considered that the input is at a high level? When Vin<min...
Hi, Please advise . I've been designing with the STM32G0B0R at my company. I have some ports connected to a ULN2003A driver input and ouputs to a relay's negative return, since the relay is conneted to 12V . specifically PC10, PC11. PC12,PC13. the UL...
Hi, I have an IAP project which have image A and image B. Image A is on flash bank1 and image B is on flash bank 2. When I run image A and upgrade image B, I will trigger the bug when doing soft CRC. The system is running on freertos.My soft crc code...
Hello everyone, I'm facing an issues with STM32H750 custom Board. Configuration: 1. FMC connect 32MB SDRAM 2. 32MB QSPI (Code run at QSPI) 3. 1024x600 16bit TFT-LCD(Framebuffer locate at SDRAM 0xC0000000-0xC012C000) ...
Hello folks,Anyone knows the default CAN clock frequency on STM32H753 MCU when powered on, assuming the CAN bit timing register (CAN_BTR) was not set by FW during the initialization?If this value would be a random, could it be changed depending on re...
Hello comunity, I am using the CMSIS DSP library in order to perform FFT to 1412 sample set with a sampling freq of 16.83Khz. I am trying different approaches to find the 16th harmonic after the fft, but i get an inaccurate value. for example, Zero-p...
