WebApr 9, 2024 · Doing GPIOA->BSRRL = GPIO_BSRR_BR_4 will put a 32bit value into a 16 bit space. That may work, but doesn't feel like the right thing to do. For now I'll just do GPIOA->BSRRH = ( (uint16_t)0x0010), but I would like to know why the STM32F4xx.h is like it is. In the STM32F30x.h the BSRR is 32 bit and makes sense. meat sharing platter

On the GPIOs of some ARM-based microcontrollers, you are given a register BSRR which you can write to to perform atomic changes in a ports output register. For example, to set Port A Bit 5 to a 1 you simply do GPIOA->BSRR = (1<<5) This alleviates the problem of atomicity so you do not have to perform a read-modify-write sequence. WebJul 25, 2024 · MCUFRIEND_kbv library works fine with STM32F103C8T6 but you have to use the preferred "Adapter Shield" wiring. I have no connection with Adafruit_TFTLCD_8bit_STM32 and nor does Adafruit (as far as I know) Note that the SPFD5408 is very similar to the ILI9320. Most hacked Adafruit libraries support ILI9325. meat sharing board

Why does setting up some GPIOs cost so much memory?

According to the Nucleo schematics, PA2 & PA3 are connected to the internal ST-Link controller, therefore not usable for GPIO without adding and removing some bridges first. That's your MCU, "SB62, SB63 Default open" means that the connection is not there. And this is where it's connected to the ST-Link interface.

Lower 16 bits have 1's where bits are to be set to "HIGH". Upper 16 bits have 1's where bits are to be set "LOW". 0's mean ignore. In this case, to set and clear A2, A12, A13 while preserving the state of all other pins in the port, the code is:
