Uart bulk data transfer
Helloi need some help in transfering 24 bit 3 channel adc captured data via uart. SPI based ADC sampling rate is 4ksps i.e. I get dataready interrupt at every 256usec . The total bits per second would be then 4000x9x8 equals 288000.Can anyone help me...
STM32H5 GPIO toggling performance
I use STM32H562 and/or STM32H503 (nucleo board). When try in loop only this line: while (1) { GPIOB->ODR ^= GPIO_PIN_6; } The frequency on pin is only 12.5 mhz. I use external quartz 8mhz (and 24mhz on nucleo) I config to 250mhz (with build...
