To test a USB implementation, I have implemented a USB loopback on a Nucleo-144 Development Board (MB1404C). Testing is showing a strange result that I have been unable to isolate:The code is very basic: it creates a thread for USB data handling. ...
ref. RM0440 Rev 9 vs STM32G4xx HAL v1.2.5.0 (en.stm32cubeg4-v1-6-1.zip)DMA_CCRx.EN - Channel enableThis bit is set and cleared by software.When a channel transfer error occurs, this bit is cleared by hardware.DMA_CCRx.TCIE - Transfer complete interru...
I am trying to use the FreeRTOS on the STM32N6570-DK board, and now I have some problems with it. I downloaded the RTOS from the website and I get the croutine.c, event_groups.c, list.c, queue.c, stream_bufffer.c, tasks.c, timers.c under the route o...
I have NUCLEO-F756ZG board with STM32F765ZG and I have hooked up ICS43434 mic into I2S1 bus. Now I have been scratching my head for a day to figure out how to get data out from that puppy. Or actually getting data out is simple, but to make it sane i...
Hi all,I am writing to you because I am trying to understand how to make the USB CDC ACM work on the Nucleo U5A5ZJ board. First of all I analyzed some ST webinars and tested the UX_Device_CDC_ACM program which works correctly. I tried to reproduce it...
Hi!I'm trying to make a LCD screen work, but without success.I found this library:https://github.com/STMicroelectronics/stm32-ssd1315But I can'd find more documentation with examples (how to initialize).Can you give me a "wire"? Now I'm using a ssd13...
The HAL tick timer interrupts the MCU every 1 ms. When using FreeRTOS it is best to set the HAL Tick source to a timer rather than the system tick interrupt. Delays in freeRTOS are created using vTaskDelay() or vTaskDelayUntil() and don't use the HA...
Hi, In most of my projects I use the CCM memory for the stack and heap and as it is limited, the question arises how much should I allocate. I specify the stack and heap in the linker script: When using FreeRTOS teach task maintains its own stack, ho...
Hi @stm32 I have a STM32G070 chip connected to a NOR_FLASH MX25L6433F using Standard SPI. I created an External Loader for the setup, but unable to read/write using the stm32 programmer. The custom driver for the particular flash is proved to work wi...
hello i have stm32f429i-disco card. fmc settings are configured. i defined sdram in the linker file but variable sdram is not written. can you help me? i am using cubeide. my linker file is attached and i am attaching the photo of my fmc settings. my...
