Received display

Today, i received the 4.3" lcd-tft display, as always i got very exicted, started took all my tools and required components, we to uni's (i study at University of Leeds) ARM lab. Started soldering, the friend lcd-tft module. And i have an stm32 f767Zi Nucleo board, since my STM32 H7, board did not arive ihad only this boards which has the LTDC (LCD TFT Display Contoller) Pheripheral. So i started a project in the cube ide, opened my ioc file trying to figure out the pins, since its a 24bit rgb display, I had to hook 24 wire for data transfer (R0-R7, G0-G7, B0-B7), then HSYNC, VSYNC, CLK, DE, along the power pins were connected, first tired powering up he board it worked turned out with the backlight turned on. Then tried confugiring the clk for the ltdc controller, and tried a sample code where the colour of the screen changes few mins once. And it worked in the first attempt, I have attached the video below. Now i wanted to test out the pwm brightness control, the frequency was 10KHz, and tested with 0 - 99 % duty cycle. After that i wanted to test out the Touch since this is an resistive touch display, i was not sure how to use this i asked codex to help me test this out, so it said both the X and Y axis pins +ve pins should be connected to an adc and the negative pins to the gpio inp, i was working, but the issue, was there we lots of blind spots, in the edges of the device which it could not detect, so i was searching if there is any module where i can connect and receive the data using a protocol, ended up finding, TSC2007 I2C Resistive Touch Screen Controller, so i am gonna order this soon, also the ble module which i order was wrong it is only capable of transfering and receiving the data it does not have an audio controller, airpods like apples, require a A2DP Controller, so i am gonna find a new module and order that soon.

What I did

• Tested out the 4.3 inch tft display and the the 40 pin fpc friend module.
• Also tried using the pwm brightness control, duty cycle was around 10KHz
• Did try 24 bit mode, tired using the touch screen using adc and i did not work accurately.

Next

• Wait for the remaining components, and will start testing each sensor one by one.
