STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hello, I tried to run the RTC DS1307 first using libraries available on the internet. It was not successful. Later I tried to run the communication "manually" but it doesn't work either. Please help. The module with DS1307 works on Arduino. Through t...
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...
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 ...
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...
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...
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...
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)
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...
