Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
I've been struggling to get FatFs working on a NucleoH7A3 board for a while. I built a little board with a uSD card connector that plugs into the Arduino connectors on the Nucleo board. The pins for the uSD card connector are connected to the same GP...
Hello,I'm trying to get some audio samples with 24 bit resolution from the SAI (RX, connected to an external ADC) into SRAM via DMA.When DMA data sizes / alignments are set to WORD (32bit) for peripheral and memory everything works fine.To save some ...
I would like reduce power consumption from USB host when my device do not used by application on USB Host. I would like use STOP1 when device in suspend.As I know USB Host should stop send SOF(when device is no active) and after 3ms device should det...
I'm trying to make a program one of the features of which is SD card support. I'm using HAL libraries entirely, it's hard to find an example that combines SD card, SDIO communication and HAL libraries.1. problem is that function f_mkdir, f_open retu...
I am using lower power mode for my application. When I enable sleep mode in the task it is getting waked once it enters the sleep mode. I want to my application to stay in the sleep mode until the external interrupt occurs.
I am working on a design using STM32L433 as a composite USB (CDC and MSC) device using the STM32L4xx HAL and FreeRTOS. I have the device enumerating and I now need to add access to the storage medium (eMMC). The challenge I am facing is that the devi...
I'm trying to understand how the internals of FreeRTOS work and in particular I'm curious whether FreeRTOS thread execution and handling only occurs with 1 ms "granularity". Let's take an example, let's assume I create a thread that only takes 0.3 ms...
Hello,i have an issue with erasing flash on STM32G4.When i try to erase addresses above half of the flash (above 0x8010000), it does not erase anything. It works when i try to erase below this address.However the function HAL_FLASHEx_Erase returns HA...
Hi!I currently work on USB composite device (CDC + MSC). I putted together a program with help from:https://sudonull.com/post/68144-CDC-MSC-USB-Composite-Device-on-STM32-HALhttps://www.programmersought.com/article/18127793400/The thing is, i don't kn...
