Hi,I can read/write an external sdram using fmc in stm32f429. But working with address and read/write functions is not proper for my purpose. I want to introduce external sdram as if internal sram is clearly extended and whenever I define a big varia...
Hello I was hoping to get some guidance on what the best way to read an 8bit register, clear and set a few bits, then write back to the same register using the HAL_Transmit function. I am using a TI LP55231 9 Channel LED driver. Datasheet is located ...
I'm using STM32L412KBUx on NUCLEO-L412KB, STM32CubeIDE, Version: 1.8.0.Design: ADC1 is set up to continuously poll several channels and update locations in RAM with DMA.After a period of inactivity, the application goes to sleep. COMP1 is used to det...
I use cubemx to generate clock configAnd I use a flip pin and oscilloscope to check the speed.here is what i didclock settingvoid SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; ...
Hello Guys,I tried to find a list or something which gives me an overview of how many and which pins can be configured as PWM Generation Output for the named µC. In the Datasheet of "STM32L151x6/8/B STM32L152x6/8/B" I found a table named "Timer featu...
This is the board picture: I bought it from Aliexpress, I tried to connect it to Arduino IDE but didn't connect.There are two boot pins, how to use them ? What should I do exactly ?On the device manager, it displays this message:
Is there a way to create user defined IRQ handler type that could be called from NVIC ISPR ? I would like to interrupt execution if some particular software condition is fulfilled..
Dear Madame or Sir.We have a problem to setup a TTCAN BACKUP-TIME-Master in STM32H743 MCU. .We have two NODES.ONE should be work as CURRENT-TIME-Master and the other node, if MASTER fails, as BACKUP-TIME-Master.But it seems to be (according to the TT...
After about 14 minutes of normal communication with the chip through spi as the source below, it falls into an infinite loop.Why do you fall into an infinite loop?please I'd appreciate it if you let me know.int spi1_writeread(const unsigned char* txb...
Hi,Can I directly write in memory-mapped mode over QSPI of STM32H7 to NOR Flash?Thanks!
