I am using an STM32 Nucleo H563ZI board for stm32CubeIDE and I am trying to send AT commands to a Telit LE910C4-WWX threadx modem over usb using the usbx host and threadx middleware. My program should be able to detect the modem as a cdc acm dev...
Hi,I have an STM32L412RBT6P microcontroller and a CFAG12864T3-NFH LCD which uses an ST7565 controller. I want to use SPI to communicate with the LCD and leverage DMA to efficiently transfer data with lowest current consumption possible. Could someone...
I have a high-resolution timer configured at some frequency. This master timer has three other timers associated to it, where each timer also runs at the same frequency. But the trigger events of these timers are compare values from the master timer,...
Hello @ST Community I am using STM32F769I-disco to save real time data in SD card with SDMMC2 & FATFS. The sensor value are type float. The problem is that there are saving data in the file of SD card but the screen freeze.this is the code that i am ...
Hello,Because there are negative side effects of using FatFS in my program to write logs to an SD Card, I am trying LittleFS library with an implementation of the HAL library.When I mount the filesystem &lfs I get a result of -84 which indicates that...
Hii I am using STM32F103C8T6 controller and i want to initialize UART 7-Bit mode as per this configurations none Partiy Bit and 1 stop Bit. But in the controller has these two parameters UART_WORDLENGTH_8B & UART_WORDLENGTH_9B. Then how to init UART...
Hi all,We want to make an application where users can update their devices. We want to rollback if the update failed. For this, we initially took a dual boot bank MCU, the STM32L471RG. But after being busy building a bootloader for it, I don't know i...
hello, I use STM32CubeIDE 1.16.0 and working on a custom bootloader to jump to application at address 0x08100000, here're the jump code below: void jump_to_application(uint32_t flash_address) { void (*app_reset_handler)(void); uint32_t main_st...
Hi Guys, I'm working on a personal project. I have experience with the use of STM Nucleo and this time I don't know how to get out of my problem. Previously I have already used the UART peripheral in the same way that I am using it now, but now it ha...
NUCLEO-G474REMy design uses two timers, one in master mode(TIM20) and one in slave mode(TIM1).To have the master timer generate an update signal in the trigger output, I set its TRGO event selection as "Update Event". the CR2 value 0x200020 confirms ...
