Hello @PMato.1 , I was able to figure out the problem I was dealing with. My problem was that I was addressing the wrong bits when for the data lines because it functioned differently than the resources I was looking at. I was using an 8-bit data bus with the FSMC to control my screen which is slightly different than a 16-bit data line. I realized that this driver does not really have a standard so I had to adjust some different sources for my initialization code. The main issue was that with an 8-bit data line the bits are shifted over from the 16-bit data line so my code was not initializing the screen properly because it was not receiving the correct data from write data command. Here is a resource that I used to help me https://github.com/hampussandberg/HexConnect/wiki/LCD-ER_TFTM070_5
In the screen shot I attached is the section that helped me figure out my issue. On this it was different for the what to use for commands and data. I am not really sure why it is different but I think the resource might have been wrong or it is just different for an 8-bit bus than for a 16-bit bus. Here is what my write command and data functions looked like:
void Write_Command(uint8_t command)
{
//IC_RD = 1;
//IC_A18 = 0;
//IC_WR = 0;
//IC_CS = 0;
//Send Command to the Data Bus
*(__IO uint8_t *)(0x60000000) = command;
//IC_CS = 1;
//IC_WR = 1;
}
//=================================
void Write_Data(uint8_t data1) //8bit data
{
//IC_RD = 1;
//IC_A18 = 1;
//IC_WR = 0;
//IC_CS = 0;
//Send data to the Data Bus
*(__IO uint8_t *)(0x60040000) = data1;//test
//IC_CS = 1;
//IC_WR = 1;
}
As you can see sending data is different from the resource that I was using. I just had to shift my stuff over a bit and then it worked. A lot of this is dependant on my project, considering I was using A18 for my select bit and I had an 8-bit data bus and how I wired things up. I am not sure if this helps because I do not know if you are using an 8-bit or 16-bit line or what your exact issue is. This is just how my issue was solved so I hope it can be some help for you to figure out your issue. Reading the datasheets of the STM32 and the LCD driver, helped me understand a lot of what was going on and figure out what issues could be arising.
