Hi friends,I have DMA2 moving data between a look-up-table to GPIOB. DMA is fired by TIM8 that generates constant sampling time.The system works fine, but when main loop have some instructions (dummy instructions that doesn't affect DMA system), DMA ...
Dear Members,I changed my clock from MSI to HSI but my SPI and UART baudrate becoming wrong,What do I miss here ?thanks

Hello, I want to know if it is possible to set date and time of the RTC in the main() function.I'm working with the LSI and I know that is very inaccurate. My idea is to -"re-initialize" (set manually the date and time) the RTC every 1 week for examp...
Hi!I have been making soem firmware for a small device, and so far have been developing it on a Nucleo... all has gone relatively well so far...I'm now trying to get it running on a standalone chip so that I can put it on a custom board. But all is n...
Hi.I'm having some difficulties with the flash self write. This is a 2 part question, they are related but most likely with different causes and solutions. Background: I'm using a STM32L476R6T6 (256Kb flash) and I have a bootloader that erases th...
Hi.I'm a beginner in programming stm32 microcontrollers. I am developing a control for brushless motors using DMA.I am using the microcontroller STM32F103C8T6 (Chinese development kit "bluepill") at 72Mhz.To connect two LEDs for test, set 1 TIMER1 PW...
However, the values that I obtain (I show them on LCD display) are not only inconsistent, but also the potentiometer's rotation doesn't effect the value? I have searched a lot and tried different ways but I couldn't find the problem in my code. Pleas...
Hi,I am using STM32H750VBT6 microcontroller and want to use IS25LP016D-JBLE flash as QSPI external memory. Is this flash supported in STM32?? If yes, how can i add this flash while flashing using keil IDE.
