I'm trying to calculate the period of DMA ADC interrupt triggered when the destination buffer is completely full. As of my understanding the period is:T_dmaDone = [(T_sample + T_conv) * sampleCount * channelCount] / F_adcIn my case each rank is set t...
Hello,Comparator in STM32G4 is very fast. some glitch which is detected by COMP (during commutation PWM).The overcurrent detection using internal comparator triggers below the theory (40A insteand 100A for example) I'm having trouble implementing the...
Hi, could someone explain me what is the difference between wake up and alert in RTC?For example the UM1749 provides information about RTC Alarm functions (section 39.2.8) and wake-up functions (section 40.2.2)When should I use the wake-up and when t...
Hi Team,We are using STM32F072RB MCU with discover EVM boardWe are using STM32CubeIDEWe are using SPI1 and SPI2 as slave mode configuration Query: we observed that the FIFO full and overflow is happening @Spi slave while receiving the data stream @1M...
hello，I want to download software from ST Website ,but there is not button to supply. when i didn't log in, there was a "get software",but after i logged in, it disappeared.thank you.
I'm just getting started with the STM32, only got the NUCLEO-G474RE board yesterday.I need to communicate from a PC to the STM32 over USB. Am I correct in assuming that the CN1 USB connector is only available for ST-LINK, and I need to attach a seco...
Hello,I have created a bootloader application that jumps to main application at 0x08010000.It works fine, except when I run in debug mode. In this case, the first execution runs correctly. If I push stop and restart button the application goes to STK...
Hi I'm new in working with CAN-bus. My project involves two stm32 boards (both are nucleo-l433rc-p) and I want to get CAN-bus communication between them. The code is supposed to make a build in LED blink each time the blue button on the main nucleo b...
Hello, I'm testing the STM3240G-eval with the USB host MTP. The goal is to retrieve the photo from a canon EOS 100.The camera uses PTP protocol.As the demonstration code read .wav file, I wrote a wav file to the root of the SD card. The digital came...
The current system is configured as shown in the figure above, and the serial communication is using RS485.In the system configuration, UART3 and UART2 are used, and the message from the PC through UART3 is delivered to the device through UART2 from ...
