Posted on October 20, 2016 at 20:04 I'd like to implement vPortSuppressTicksAndSleep() to put the MCU into sleep or stop mode when there is nothing to do in FreeRTOS tasks. It should be woken up by an EXTI interrupt or RTC wakeup. In my implement...
Hello,I am on a new project that is sending SPI data every 200kHz (real time very important). I work on a STM32F722.I want to use HAL_SPI_TxCpltCallback() to know when the transmit is finished, but I don't want to use the HAL drivers.Indeed, when I u...
Hi everyone !!I am using a virtual com port (VCP) to conect my device to the computer. Everything was running well till i decide to comunicate with a windowns 10 host. I realized two diferent situations :The first was when i started the device with a...
Hi All, I created a test project to Wake Up the device from STOP Mode when it receives data over UART. I ported code from "UART_WakeUpFromStopUsingFIFO" available at /STM32Cube/Repository/STM32Cube_FW_L5_V1.3.1/Projects/STM32L562E-DK/Examples/UART/Ex...
Inquiries regarding spiritDSP.We are implementing mp3 with DAC DMA using SpiritDSP.The time to play depends on the samplerate and bitrate of the mp3 file.The original time is 3 minutes and 10 seconds,The playback time is different as shown below.The ...
I'm having problems with the PDM2PCM lib and am getting desperate.I have a STM32L151 with an external clock source of 8.192 MHz. The SYSCLK runs with 16.384 MHz. The APB2 (SPI1) runs with 4.096 MHz.I'm sampling a PDM mic with an 8-bit SPI at 2.048 MH...
Hello, I'm using ST32H743ZI2 nucleo board as TCP client. When I setup the ethernet configuration/initialization, I considered the https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working article.Additi...
I am trying to post data using MQTT in LWIP drivers. I am able to bring up the ethernet connection, can ping from PC to STM32F767 device as well. Tried to connect to MQTT broker. When publishing message I get an error as follows:-tcp_write : could no...
I have both TX and RX on SPI1 on a F407 running in DMA circular mode. In the HAL_SPI_TxRxCpltCallback I parse the data that I receive from the Pi (since the Pi and the STM32 communicate over SPI1). Does the TxRx callback get called when BOTH, TX and ...
