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...
I USE STM32CubeIDE Version: 1.16.0 when build the project massage arm-none-eabi-size and the hex elf or bin files after download to stm32f107vct6 no actions nothing also i use cubemx last ver for generation code thanks
Hello everyone! I have a very important question about a PCB design that I'm making.I basically have a PCB with a bunch of sensors, a 4Gb eMMC memory and a USB-C connector. Here's the related schematics : - Power section : - Microcontroller (I'm sorr...
Hiwhat is the relationship between the speed of the CPU and the GPIO response. for example, I have a CPU clock of 72MHz and a GPIO clock of 36MHz and I set the pull-up when is this pull-up visible to the CPU because e.g. I would like to read the port...
