How to connect to AWS or any cloud services using STEVAL-STWINKT1B or B-L475E-IOT01 Discovery Kit?
I am fairly new to STM devices and I have faced the same issues after attempting to follow their guides. The board itself is able to show readings of the sensors and such within Tera Term and whatnot, but whenever WiFi is involved, the device just se...
Enabling SDA and SCL pins in the Nucleo board for I2C communication.
Hello, I have written a code for I2C to act between two Nucleo boards, however, at the moment, the master board is not even giving me a signal output. I looked at the output using a Saleae Logic Analyzer and there isn't even a clock signal comin out ...
Why would SPI send 16 bits instead of 8?
I have configured my STM32G071 SPI peripheral to transmit 8 bits with the following code:void spi_config(void) { RCC->APBENR2 |= RCC_APBENR2_SPI1EN; //Enable SPI Clock //Configure for SPI mode (not I2S mode) SPI1->I2SCFGR &= ~SPI_I2SCFGR_I2...
Resolved! Is this possible to disable / monitor trigger memorization on DMA on STM32U575?
ContextI am working on NUCLEO-U575ZI-Q with an external ADC wired to the board. The ADC generated a rising edge on one of its pins, "DRDY" each time a sample is available.My objective is to retrieve the ADC sample without involving the CPU. The curre...
I2C strange signals form
I am now dealing with the work of I2C. As a device, I connect an Eeprom AT24 chip. There are 10K Ohm pull-up resistors. There are no other devices on the bus and nothing else is connected to the boards. Transmission rate 400 kHz.When I connect Eeprom...
Resolved! STM32F303 - is it possible to read the state of PB14 when in MISO SPI mode?
I have an ADC chip, CS5532, that sets the MISO line on PB14 Hi if data not available, and Lo if it is. Can I read the state of the MISO line?Every time I try to do it I read that the pin is Hi (I am reading the IDR register)
How to generate an arbitrary signal using DMA? (F446RE)
Hi everyone,In my project, I try to create a TTL signal generator, and I found a useful function that uses DMA on PWM signal (HAL_TIM_DMABurst_MultiWriteStart), so that I can create arbitrary rectangle signal that I want. I am using a timer frequency...
How to read SPI_MISO from sensor (A111) to STM32G071CBx MCU? (XE132/XM132 from aconeer)
Have tried using hal_spi_transmit and receive but cant figure it out, any suggestions?
