I detected that transmitting 68 characters using RS232 at 460800hz takes 30-32000 tics to micro running at 480Mhz (HAL_UART_Transmit() takes 10 times more).Is there a method to disturb less to micro to make that transactions, perhaps using DMA?Is bet...
I have seen that it takes about 28 ticks to read registers, so I think my stm32h750 runs really at 17Mhz, it seems is not risk, so perhaps it exists another more fast stm32 micro that have more 17 MIPS 
I would like read the gpio lines at fastest speed. As example it is possible to read first 4 ports by reading:uint16_t ports0123=GPIOC->IDR&0x000F; (it is very fast, takes 28 tics)It is possible to read ports GPIO_PIN_0-15 by connecting GPIOC->IDR to...
I would like use HRTIM timerA interruption event, so I where looking for the weak function to rewrite it but not found it.I found that I must set compilation flag USE_HAL_HRTIM_REGISTER_CALLBACKS to 1 and make all functions as weak. If I make so stro...
I made following two versions of the same software to process DMA data, one using floats and the second using uint32_t to try run faster, but as a surprise the first one run faster:  //161 void process_data_ADC1() { float samples1=(2.0f/(float)ADC_B...
