Hi! My project is to control an alarm system via the microcontroller stm32f207vft6. I am using keil development environment. at first, I start programming drivers I / O (LCD, KEYBOARD, LEDs) that I will use in the main program.   I have a problem with the lcd driver. I must program general functions,for example, towrite, read, delete, move the cursor from an LCD 2 * 16 display using 4 bits mode. LCD_B function allows to write the data port I dont know why it doesnt work. i still always have a compilation error.
