Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
using cubeMX tried to interface USB port, at first time when it is interfaced with PC it makes data transferring but once hard reset is done thereafter it does not work.please guide me how to make this to work at all time thankschandrasekaran V
I'm developing firmware update for an application based on a STM32F072, using the built-in bootloader via UART1.The method to enter bootloader is jump to Bootloader addres (as found on ST community discussions).I managed to get Bootloader commands wo...
Hello,I'm using STM32H747I-DISCO Discovery kit with STM32Cube_FW_H7_V1.6.0 and currently doing some USB testing. So far everything works fine and I was able to get to work everything I needed, but I'm unable to turn off external VBUS. The board conta...
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, ...
