Hi, I would like to identify the source of the interrupt that caused the MCU to wake up from Standby mode. To do this, I check the RTC_FLAG_WUTF and RTC_FLAG_ALRAF/RTC_FLAG_ALRBF flags after the system wakes up to determine the wake-up source. Howeve...

Hi, SofLit @PGump.1 @When reading the FIFO buffer through I2C read command, we typically retrieve 6 bytes of data: 3 bytes for the Red LED value and 3 bytes for the IR LED value.The question is: how is the data arranged in the 6-byte buffer?Is it or...

Hi, I am configuring the ADC in single-channel continuous conversion mode using DMA. However, once I call HAL_ADC_Start_DMA(&hadc, &AD_RES, 1), the main loop stops executing, and the HAL_ADC_ConvCpltCallback() function is not triggered.I noticed that...

Hi, I would like to use system wake-up pin 1 (PA0) as an external interrupt to wake up my MCU from standby mode. Understand that a rising edge on PA0 (wake-up pin 1) should trigger the MCU to exit standby mode. However, I am encountering difficulties...

Hi, I would like to separate the project files (.project) and source files into different directories as shown in the image below. How can I do this? In my original project, I don't want my source files and project files (.project) to exist in the s...

Ok. To understand the behavior of I2C when reading multiple byte, is the first byte received is stored in buf[0], the second byte in buf[1], and the third byte in buf[2]?
