What is the expected RTC peripheral behavior through power cycles on VDD? We have a 3.3V system design with the STM32H562VGT6 right now.Setup:VDD = 3.3V from external supplyVBAT = 220mF supercap attachedRTC is enabled & counting, system is stableLSE ...
Hi,I have an application where I am trying to read some pulsed inputs from an optocoupler (for isolation) which consist of pulled high inputs on the STM32 MCU, the problem is it keeps crashing when connected directly to the optocouplers randomly when...
Hello,I'm trying to setup a SPI communication through DMA but I can't receive data.I use a STM32H7 microcontroller as a single master to reach a single slave. I would like to transmit 1 byte, and receive 1 byte in return. To start the transfer, I cal...
We apologize for changing the subject again and not responding to your request, but today we discussed this project with our teacher, who told us to first focus on the implementation of Wake on LAN and to be satisfied with putting the device in stand...
Hi there,I've crated a STM32H7 project using the Riverdi 7" example from touchGFX which starts up with no errors showing a picture on the screen.When I add a circular DMA buffer for ADC3 in the M4 context (only). The generated M7 main file changes th...
HELLO, Can you please suggest us any mcu having internal block for zero crossing detection in stm32 for 50 - 60hz frequency signals or any slave chips that are dedicated for zero crossing detection. Thank you, Krishna.
Hello. I am currently using USART6 by setting RX as interrupt, and TX as DMA in STM32F4.The ST board mostly worked well, however, after some hours (maybe 10 hour), the RX interrupt wasn't called. I suppose that this problem is not related to hardwar...
I'm using PWM with level shifter(BSS138, 74HCT14D, TXB0104) for developing IC embedded LED (such as WS2812) However, when I captured this siganl using scope, I found that the signal was not clear.Below are the pictures that I captured. 1. Before addi...
Hello,I have been working on creating an SPI loop using the SPI callback function to alternate between two sensors that share a common SPI SDI/SDO line. However, I am encountering an issue where the SPI transfer complete callback is triggered, but t...
Dear Team,We are currently in the process of selecting components for our project, and we have identified the STM32U5A5QJ9(STM32U5A5QJ , foot-print size UFBGA 132 7x7x0.6 P 0.5 mm) microcontroller as a potential candidate. However, upon reviewing th...
