Hi guys,I am currently trying to read the value of the WhoAmI register using SPI communication with the ICM42688P, but it returns 0xf3 when it should return 0x47. Is there something wrong with my program or configuration?Please tell me about it. .hpp...
I want to continuously measure the frequency of signal1 relative to signal2.Signal1 can vary between 1-80 MHz, signal2 between 5-15 MHz.My approach is:Timer1 counts signal1.Timer2 counts signal2 with a counter period of 200. This gives me an event ro...
Hello,Does the STM32U575CG/I (48-pin package) support USB communication, or is USB functionality only available on higher pin-count variants?Thank you.
A client asked me for a code quote to control an ILI9341 TFT LCD. In my opinion, a Cortex-M0 would do the job, but I only found a Cortex-M0+ that has one core, but this only has prototyping boards for wireless solutions.Would I be right in my choice...
Hi guys: My project DAC setting as below: And my project that initial and code as below, it's works on EVM board (STM32G474RETX), but now works on STM32G474MCT3TR, does anyone encounter this situation? static vo...
Hello!Prehistory:USB DFU works flawlessly on another my design which is based on the STM32H743ZGT6.When it is powered on with BOOT0=1, I measure 3.3V on the USB_DP processor pin with a USB cable disconnected from the board.Problem:There is a USB DFU ...
Hello everyone.I am currently considering using the STM32H735 AD converter.As shown in the figure, I have inserted a Schottky barrier diode and a 1kΩ resistor just before the ADC terminal pin for overvoltage protection.I was curious about the input i...
Good day everyone. I am working on the STM32H7 MCU and using the HAL library for controlling an SPI in DMA mode that has to exchange data with an external device in real-time. I'm working at the maximum possible CPU frequency and using the -O2 optimi...
Hello I am validating the ADC DMA Timer using stm32u5I am doing when ADC and DMA are working fine but timer is not working getting into the error handler what I am doing is I want start ADC and DMA when timer trigger but the timer is following error...
I'm working on a custom PCB with an STM32H750VB and the ST-link is unable to find the target in both CubeProgrammer and St-link Utility via SWD, below are screenshots of some of the error messages I received and our microcontroller schematic. I've pr...
