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...
Hello,I am trying to enable the USB IP DMA mode on an STM32U5A5. Without DMA, I have it working as a USB device and it transmits and receives data without apparent issues. To start using DMA, my understanding is that all I need to do, in CubeMX, is c...
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...
