I use dual flash bank in STM32L4. I perform a flash bank switch by programming bit BFB2 in OPTR.Sometimes, after the new software has started, RTC seems to be returned to reset state: date and time are lost and RTC internal registers are cleared! In...
Hi,I'm using two STM32F407 LQFP-144 in SPI communication , one Master and one slavewhen power supply is connected and program is running and spi send & recieve is okay , we disconnect board ( wiring) and then connect again , face off over heating ic ...
In STM32F429 IN application programming i dint get one point where on booting from flash and the custom IAP application checks if there is application in vector table addresses with application address ?/* Check Vector Table: Test if user code is pro...
i would like to connect TIM3 to pin PA6 for PWM, using above command, but it is not working in Keil.more over i would to generate starting delay in PWM , i mean PWM signal should start with x delay How can i do above ? thanks
hi, I am ankit and using STM32F4 discovery board. I am new to ST and beginner in C programming too. I have to send command sequence in hex format to another device whose details are...baud rate 9600/19200(default 9600)paririty NONstop bit 1data 8 bit...
Hi, I am working on STM32F56G eval board. I need to generate a PWM pulse with varying time period on a single channel. I am new to stm32 PWM. With DMA burst code example time period is changing on the runtime .How can I generate a PWM pulse with diff...
I am trying to find the datasheet, reference manual for STM32 Nucleo 144 - F429ZI board.Basically, the document which talks about Functional block diagram - how the GPIO pins are connected to which bus. Next, I am looking out for the reference manual...
Hello All,I recent implemented a DMA transfer for SD card data to RAM (technically an external SDRAM) on the STM32F765VI. Previously we had been using an IT transfer. In other words, we are now using SDCard_WriteBlocks_DMA rather than SDCard_WriteBlo...
why is it equivalent to the use of global variables, the address will not change.
Hi community,I am trying to get timer3 to trigger on a rising edge, run for one 10ms pulse and then stop until it is next triggered. Application is AC phase control for a simple SCR circuit with 2 optos. I nearly have it working, but essentially, it ...
