Hi,I'm trying to write RGB data directly to an 8+8+8 bit i8080 screen using the DMA2D and FSMC peripherals on a STM32U575 Nucleo board. As a test, I set up the FSMC and manually sent data one uint8_t byte at a time - this works fine. However, I'd lik...
I am using an STM32L562VET6Q. My device contains both a (custom) bootloader and an application. The bootloader jumps into the application by reading the address of the Reset_Handler from the application's ISR vector then branching to this address. ...
Hi!I am building PCB around STM32F469ZET6.Now LSE and HSE crystals and accompanying capacitors need to be chosen.AN2867 says capacitors values should be CL1 = CL2 = 2 x (Cl - Cs)Cl – crystal’s load capacitanceCs – stray capacitance of oscillator circ...
Board: Riverdi display with STM32H757XIH6 MCU; using TouchGFX and FreeRTOSI think I know how BASEPRI register works and how it is used in FreeRTOS. What I do not know is where is the value of BASEPRI register set at the beginning of the program. I no...
Hello, ST experts STM32F417 is used on custom hardware design. And everything is OK except SD card. At first SD card works well. f_write takes about several milliseconds. But when the free space of SD card(San Disk Ultra 64GB) is less then e.g. 10GB,...
Hi I am using STM32F401RE controller but on my PCB, so here can I use the pins allocated for its programming/code dumping also as normal GPIO's. Any precautions which needs to be taken care of?
Hi, I am developing digital control for power electronics for which ADC conversion time is critically. In stm32f334r8 reference manual I saw it takes only 0.19us at lowest sampling time i.e 1.5 cycles. when I tried to measure the adc conversion time ...
Hello! I have a Nucleo Board MB 1641 (STM32WB15CC) and I am developing an application using BLE, in P2P mode. Including based on the usage example provided by ST.The application needs to transmit from the UART to the BLE and return the response from ...

Hello everyone!After many hours of grinding through forums & discussing with ChatGPT (really, ChatGPT is like my best friend now), I still fail to understand what must be a simple notion with an easy solution. This is why I'm posting this in forums. ...
