(STM32Cube_FW_F1_V1.8.2/Drivers/STM32F1xx_HAL_Driver/Src/stm32f1xx_hal_i2c.c)In HAL_I2C_Mem_Write_DMA, hi2c->hdmarx may be null but this is not being checked. This causes a crash when invoking HAL_DMA_Abort_IT if there is no DMA used for receiving.bt...
I am selecting the microcontroller for an application that needs to implement an USB dual virtual com port (composite device with two vcom port). I would like to use the STM32F411 but i see that other people got problems trying to do it, maybe becaus...
I can send ARP, UDP, ICMP, and so on, and all the other IGMP messages, but not the IGMP V2 Membership Report messages. Wireshark doesn't show those at all, but does show the others going out. So I've written a low-level driver test that composes the ...
Hello all , Am looking to have Standard Peripheral Based SPI Flash Interfacing Example code instead of HAL based.If any one knows , pleas share.Controller am using is Stm32f103C8t6 & Stm32f072rbt6RohitROhit
Hi there!I have a Nucleo F746ZG board that I was going to use to get started with USB programming.I've read every tutorial, every correction suggested to the HAL library (which is, as per usual, full of issues) and absolutely nothing will even get th...
Hi,We are designed board using STM32F207 for USB host. I have 2 keyboard. one keyboard work perfectly & other keyboard also work but after few second automatically disconnect from host & connect it again. Same keyboard work perfectly with STM32F407Di...
Hallo everyone,I have set up Segger Ozone with a Segger J-Trace to initialize the uC. When connecting to the debuggee the clock configuration, the gpio config as well as the FMC configuration is done. After that OZone loads the programm to the extern...
I have debugged poor f_write performance to SD card on H743 and have noted, that BSP funtion waits the disk write command to complete before return. What for was it so designed? It will work much faster if to return immediately after giving the write...
Using STM32F769, HAL and CubeMX I developed a project where it is necessary to send an average of 764 bytes every 100 microseconds. For this I use the USB DMA and other peripherals.In version 1.15.0 the code works very well.After a while, I had to ad...
