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...
Good morning,I have an application based on the STM32L475 device that is running in many devices since many years ago. We have observed that, sometimes, some of the devices are resetted --> Here you have the main specs of my device:- Device is workin...
