flash write in stm32H743iit6
hi there,I have a stm32H743iit6 and I wish to write a uint32_t array in it flash. I use sector 6 to 7 of Bank1 to write my array to. first I fill my array with number of 0 to 69 like so for (int i = 0; i < 70; i++)//10 { flash_buffer_W[i]=i; } a...
Do GPIO pulldowns leak current? (STM32L0 Ultra low power application)
It has become my habbit to place pulldown resistors on inputs/outputs. This ensures that pins are not floating and are pulled to GND to a known state.Normally, this wouldn't be a problem but since I am working on ultra low power battery powered devic...
