stm32.lbr – ST Cortex-M3 STM32F101/103 processor family in LQFP100, 64, 48 and VFQPFN36
stm32_lqfp144.lbr – STM32F101Zx and STM32F103Zx. LQFP 144 package.

I hope you guys can use them… Please keep me updated with your projects

The SSD1963 chip makes it possible to control a 7″ display with a regular microcontroller or microprocessor, which haven’t got enough memory and power to control it itself, as it’s a normal display with vSync and hSync and so on.
So after a couple of hours I got it running with my STM32 board and a touch screen controller.

Please take a look at the video below to see some of the things I can show/do.

You can see some pictures about it here, but I’ve also made a video where you can see it in use.

But as it didn’t work, I started debugging using my Raisonance RLink, and just when I looked at the Device variable – a variable which holds the controller number, and is loaded at the initialization process of the display, it showed me that it was an SSD2119 controller.

So I found the SSD2119 datasheet and started recoding using the new Command calls found in the datasheet… Finally it worked and showed some life

So right now I have a working SSD2119 code with SetPixel, Text, Circle, Rectangle, Fill and some working Touch Screen commands for the onboard ADS7843 touch screen controller.

Please take a look at this image to see the display in action:

SSD2119 Pringles example

The current GUI commands I’ve made is:
void Lcd_Text(u16 x, u16 y, u8 *str, u16 len,u16 Color, u16 bkColor);
void Lcd_Line(u16 x0, u16 y0, u16 x1, u16 y1,u16 color);
void Lcd_Circle(u16 cx,u16 cy,u16 r,u16 color,u8 fill);
void Lcd_Rectangle(u16 x0, u16 y0, u16 x1, u16 y1,u16 color,u8 fill); // Slower than Lcd_ColorBox
void Lcd_Square(u16 x0, u16 y0, u16 width, u16 color,u8 fill);
void Lcd_ClearCharBox(u16 x,u16 y,u16 color);
void Get320240PictureCode(u8* pBuffer,u32 BufferCounter,u32 BaseAddr);

void Lcd_FastRectangle(u16 x0, u16 y0, u16 x1, u16 y1,u16 color,u8 fill); // Faster than Lcd_Rectangle
void Lcd_FastSquare(u16 x0, u16 y0, u16 width, u16 color,u8 fill); // Faster than Lcd_Rectangle
void Lcd_FastClearCharBox(u16 x,u16 y,u16 color);

void DispPic320_240(const unsigned char *str);
void DispPic(u16 x0, u16 y0, const unsigned char *str);

DispPic320_240 and DispPic uses a byte array to show a image – the byte array is converted from a 24-bit .BMP (bitmap) file using a program I’ve made in Visual Basic .NET!

Now it is working, and I’m able to make one of my excisting projects into a DFU loadable project (compiled it’s a .dfu filed)

I’ve also changed the DFU bootloader code to use GPIOA_0 as DFU Enable pin, and GPIOA_1 as USB Disconnect – this makes me able to use the GPIOB and GPIOC for my display without any interferrance!

Here is how you make a Ride7 project DFU loadable:

Fx.

• Virtual COM Port
• DFU Programming

As I’m using Ride7 for programming, I can upload the project and sources if you want me too.

OBS: If you have projects which DOESN’T use the USB, you have to set the USB Disconnect jupmer to Ground (Pos. 1-2), as if not, the STM32 will stop in some kind of USB Interrupt trying to make a data communication with the computer, but it never comes as the STM32 doesn’t start one!

I discovered this  when I tried DFU’ing my 320×240 LCD code – and when I went back to normal .hex, it didn’t work – that was because I had to set the USB Disconnect to Ground!
