I'm trying to use Núcleo H7 spi 1 to send a message via radio with NRF24L01, the code using HAL worked perfectly on an Stm32F103 but when i try adapting it to the Núcleo it just don't work. Can somebody help me up? The SPI clock is 100MHz , the core ...
I'm trying to write a driver for the nRF24L01+PA+LNA. I am using STM32F103, and on the receiver side I have an ESP32 with Arduino IDE and the RF24 library. To rule out a hardware issue I have programmed the STM32 using the Arduino IDE and library and...
Hello team, We have another challenge with STM32h725 controller, What I am trying to do and achieve is, Setup few external ADC over SPI bus with DMA. The ADC on SPIs other than SPI6 works perfectly. But the SPI6 is not with regular DMA but with BDMA....
In the lab with a power supply (10V 0.5A) connected to the DC bus of the IHM16M1, the 3 phases of a DC motor, and some oscilloscope probes on the GPIOs of the STM32F302R8 I probably created a short (I don't know how, I deduce).I deduce this because n...
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.
