HI, I have STM32L476RG nucleo board. I have interface a SD card using SDMMC. I have configured SDMMC as 4bit mode with TX, RX in DMA mode. I have configured FATFS. I have given 47K pull up to DO to D3 and CMD line. I am using CUbeMX 5.5.0. The FATFS ...
Hello all,2 more questions on STM32 USB CDC1) I see that it works fine for ASCII files, but when I transfer a binary file it does not. Any advice or parameter I missed?2) I get the interrupts, but how can I get an indication that the transfer has fin...
Another question:I see the the transmit and receive buffers are 2048 bytes longBut the Rx interrupts I get are after 64, 100, 164, 200, 264, 300... Bytes. Why is that ?Eli
I am using an STM32L0XX on a Nucleo-64. I am Trying to communicate with a sensor using SDI12 protocol (1200baud 8-bit even parity).To communicate properly you have to implement a question and answer session. To start with a 2-byte question response...
I use STM32CUBEMX to create code,and when the code is running,I find a problem.My code is stuck at prvCheckTasksWaitingTermination.(stm32f405 + st25ru3993)Simple Description with my system:1,freertos use systick, and HAL use TIM72,two simple task,one...
We are creating updated versions of our products; existing products are based on STM32F411, the new product versions are based on STM32F446.We have previously developed a custom firmware update tool - used for field firmware updates by our customers ...
Using Ubuntu dmesg | grep usb, "device descriptor read/64, error -71" is reported. I am beginning to suspect an issue with the USB CDC for the STM32L082 device. A recent community discussion alluded to a "device triad", class, subclass and protocol, ...
Hi,Is there any issue if in STM32H743ZI, ethernet driver I call:…. SCB_CleanDCache(); SCB_DisableDCache(); HAL_ETH_Transmit(&EthHandle, &TxConfig, ETH_DMA_TRANSMIT_TIMEOUT); SCB_EnableDCache();...so far, it works perfectly until now instead ...
Hi,I never used ethernet before, please excuse my ignorance. II dont want to use lwIP or FreeRTOS. My main goal is to use Ethernet hardware for fast communication between my distanced units. created a project for my 2 piece NUCLEO-H743ZI2 board using...
I want to start PWM DMA on channels 2 and 3 of TIM2, but I've found that it is possible to start only one DMA per timer. My MCU is stm32f103 series and my code is:HAL_TIM_PWM_Start_DMA(&htim2, TIM_CHANNEL_2, (uint32_t*)&send_buff_one , 16); HAL_TIM_P...
