Microcontroller : STM32L476RG, External flash : AT45DB041E (4Mbit, 256 bytes of page, 2048 bytes of block),SPI2 communication protocol, using HAL.I am not able to use the LittleFS library in order to read a file that is written into the flash or any...
I am new to Arm but old to assembly coding (inc Toshiba 32 bit CISC - now extinct).. Just completed RCC startup code for a STM32F344 chip by looking at the 1124 pages (!) of the RM0364 manual and the CUBE LL start up code (!!!). The CUBE code has wai...
Hello, we have Custom PCB Board which Build's around Stm32F4 Series Micro Controller.In which we have Two USB Port, One Connected with External ULPI (High Speed 480mb/s) Another Connected with internal ULPI (full Speed 12mb/s). And we are U...
Hi,I am new to DMA interfacing on the STM32 Nucleo C031C6T6 board. I am trying to send ADC conversion data to UART using DMA. I have tested the code in debugging mode, and after calling the HAL_ADC_Start_DMA() function, the program control seems to g...
I am trying to use STM32H747IGT6 as a USB device. I want to sent data using CDC. Below you can find my configuration and code. The MX_USB_DEVICE_Init() is successful. Although when I call the CDC_Transmit_FS, it never returns USB_OK and I wasn't able...
Hi all, SynopsisI have just found a severe error in FileX that looks like buffer overrun in fx_file_read(), but the problem is much deeper. This function leads to the function sd_read_data() which when invoked with use_scratch_buffer = 0 reads sector...
Hello,I want to teach kids programming at the block level using STM32, which is similar to Makecode for Microbit.Please suggest an IDE for programming the STM32 microcontroller using block-level programmingThanks
Hallo to everybody.Still working on SPI&Display adapting a code for M4 (see Different data after the 1st transfer using SPI via DMA ).I need to write only one byte at a time due to control pins of display.Starting from a NUCLEO-H563ZI and LL example...
Current working deviceFor a client we developed a device using stm32F469 that writes sensor data to an sd-card periodically. Later the data are read out from sd-card by connecting it via USB to a computer, using USBD_MSC_CLASS. The system uses FreeRT...
Hello everyone, I have enabled an spi1 port on a STM32G473CET6 as a slave and am using a raspberry pi as a master.I have verified with known packets to ensure I have implemented the correct crc algorithm on the raspberry pi both in transmission and r...
