||Software SPI Rendering||
NOTE: Hard SPI implemented Firmware is present in the replies of this thread as Revision 2. This is the soft SPI implementation.
A minimal "no active user input" software sketch combining simple breakout game with a WiFi enabled Real Time Clock module with a look up table library (which will be gradually incremented in time).
Hardware connection for WeMos D1 R1 to 1.44 128x128 SPI TFT has been discussed in more detail here (using exactly the same hardware setup):
LOLIN/WeMos/NodeMCU D1 R1 1.44 TFT Hyperclock Firmware Raycaster
The software has been wet tested with the hardware setup to run for more than two days straight without any issues.
The physics is not consistently smooth, but as God Todd would say "It just works!"
Having said that, any advice from optimizations to font size and usage, anything, are welcome, and the useful ones will be implemented in the next revision of the sketch with due credits.
Next revision will include a hard SPI version.
EDIT: Hard SPI version is out!

* โ โ COLLISION PHYSICS NOTE โ โ
* โ โ โ โ
* โ โ The game implements several sophisticated collision detection and response algorithms: โ โ
* โ โ โ โ
* โ โ 1. BALL-WALL COLLISIONS: โ โ
* โ โ โข Simple boundary checking: if (ball.x <= BALL_SIZE) reverse x velocity โ โ
* โ โ โข Elastic collision by negating velocity: ball.vx = -ball.vx โ โ
* โ โ โข Position is corrected to prevent clipping: ball.x = BALL_SIZE โ โ
* โ โ โ โ
* โ โ 2. BALL-PADDLE COLLISIONS: โ โ
* โ โ โข AABB (Axis-Aligned Bounding Box) collision detection โ โ
* โ โ โข Formula: if (ballBottom >= paddleTop && ballX >= paddleLeft && ballX <= paddleRight) โ โ
* โ โ โข Spin effect calculation: hitPos = (ballX - paddleX) / paddleWidth โ โ
* โ โ โข Velocity modification: ball.vx += (hitPos - 0.5) * spinMultiplier โ โ
* โ โ โข This creates realistic "English" effect where hitting paddle edges changes ball angle โ โ
* โ โ โ โ
* โ โ 3. BALL-BRICK COLLISIONS (Most Complex): โ โ
* โ โ โข Pre-calculated brick boundaries stored in lookup table for performance โ โ
* โ โ โข Overlap detection using intersection formula: โ โ
* โ โ overlapX = min(ballRight, brickRight) - max(ballLeft, brickLeft) โ โ
* โ โ overlapY = min(ballBottom, brickBottom) - max(ballTop, brickTop) โ โ
* โ โ โข Collision occurs when both overlapX > 0 AND overlapY > 0 โ โ
* โ โ โข Bounce direction determined by smallest overlap (Separating Axis Theorem): โ โ
* โ โ if (overlapX < overlapY) then horizontal bounce, else vertical bounce โ โ
* โ โ โ โ
* โ โ 4. MATHEMATICAL PRINCIPLES: โ โ
* โ โ โข Vector Reflection: R = V - 2(VยทN)N where V=incident vector, N=surface normal โ โ
* โ โ โข For axis-aligned surfaces: simply negate appropriate velocity component โ โ
* โ โ โข Energy Conservation: |V_before| = |V_after| (speed magnitude preserved) โ โ
* โ โ โข Position Correction: prevents overlap by moving ball to collision boundary โ โ
* โ โ โ โ
* โ โ 5. OPTIMIZATION TECHNIQUES: โ โ
* โ โ โข Spatial Partitioning: Only check bricks in ball's vicinity โ โ
* โ โ โข Pre-calculated Constants: BALL_SIZE_2, PADDLE_WIDTH_HALF, etc. โ โ
* โ โ โข Lookup Tables: Avoid expensive calculations during runtime โ โ
* โ โ โข Bit Manipulation: Use >> 1 instead of / 2 for faster division โ โ
* โ โ โข Early Exit: Return immediately after first collision to maintain performance โ โ
* โ โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ

* โ โ AI PADDLE ALGORITHM โ โ
* โ โ โ โ
* โ โ The AI paddle uses predictive tracking with physics simulation: โ โ
* โ โ โ โ
* โ โ 1. TRAJECTORY PREDICTION: โ โ
* โ โ โข Calculate time for ball to reach paddle: t = (paddleY - ballY) / ballVY โ โ
* โ โ โข Predict future ball position: futureX = ballX + ballVX * t โ โ
* โ โ โข Account for wall bounces using modular arithmetic โ โ
* โ โ โ โ
* โ โ 2. SMOOTH MOVEMENT: โ โ
* โ โ โข Proportional control: movement = (targetX - currentX) * dampingFactor โ โ
* โ โ โข Prevents jittery motion and creates realistic paddle inertia โ โ
* โ โ โข dampingFactor = 0.15 provides optimal balance between responsiveness and stability โ โ
* โ โ โ โ
* โ โ 3. BOUNDARY CONSTRAINTS: โ โ
* โ โ โข paddle.x = constrain(paddle.x, 0, SCREEN_WIDTH - PADDLE_WIDTH) โ โ
* โ โ โข Ensures paddle never moves outside screen boundaries โ โ
* โ โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ

* โ โ PERFORMANCE OPTIMIZATIONS โ โ
* โ โ โ โ
* โ โ 1. DIRTY RECTANGLE RENDERING: โ โ
* โ โ โข Only redraws screen regions that have changed โ โ
* โ โ โข Reduces SPI communication overhead by ~80% โ โ
* โ โ โข Tracks up to MAX_DIRTY_AREAS (30) rectangular regions per frame โ โ
* โ โ โ โ
* โ โ 2. LOOKUP TABLE OPTIMIZATIONS: โ โ
* โ โ โข Pre-calculated brick positions eliminate runtime multiplication โ โ
* โ โ โข Color arrays avoid repeated RGB565 calculations โ โ
* โ โ โ โ
* โ โ 3. MEMORY MANAGEMENT: โ โ
* โ โ โข Static allocation avoids heap fragmentation on ESP8266 โ โ
* โ โ โข Packed structs minimize RAM usage โ โ
* โ โ โข PROGMEM storage for constant data reduces SRAM consumption โ โ
* โ โ โ โ
* โ โ 4. FRAME RATE OPTIMIZATION: โ โ
* โ โ โข Target 60 FPS with 16ms frame timing โ โ
* โ โ โข Bit manipulation for faster arithmetic: >> 1 instead of / 2 โ โ
* โ โ โข Early exit conditions in collision loops โ โ
* โ โ โข Reduced update frequency for non-critical elements โ โ
* โ โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ โ

*
* USAGE INSTRUCTIONS:
* 1. Connect the ST7735 display to WeMos D1 R1 according to the pin diagram above
* 2. Install required libraries through Arduino IDE Library Manager
* 3. Create a new file called "consts.h" and paste the provided constants
* 4. Update WiFi credentials in the main sketch
* 5. Upload to your WeMos D1 R1 board
* 6. Enjoy the game with real-time clock display!
*
* TROUBLESHOOTING:
* โข If display shows garbage: Check SPI wiring and display initialization
* โข If WiFi won't connect: Verify credentials and router settings
* โข If game runs slowly: Ensure CPU frequency is set to 160 MHz
* โข If compilation fails: Verify all required libraries are installed
NB: As of now, the program just runs, with occassional bouts of smooth ball motion. Optimizations for consistent physics are welcome (and in development).
Any suggestions made in Arduino Forum Post will be included/integrated in the next sketch revision with due credits.

* โ โ IMPLEMENTATION GUIDELINES โ โ
* โ โ โ โ
* โ โ When using these lookup tables: โ โ
* โ โ โ โ
* โ โ 1. Always use pgm_read_*() functions to access PROGMEM data โ โ
* โ โ 2. Check array bounds before accessing (no automatic bounds checking) โ โ
* โ โ 3. Scale fixed-point results appropriately for your use case โ โ
* โ โ 4. Consider creating additional LUTs for your specific performance bottlenecks โ โ
* โ โ 5. Profile your code to verify actual performance improvements โ โ
* โ โ โ โ
* โ โ Example Usage: โ โ
* โ โ // Wrong: Direct access (will crash!) โ โ
* โ โ int32_t sin_val = sin_table[45]; โ โ
* โ โ โ โ
* โ โ // Correct: PROGMEM access โ โ
* โ โ int32_t sin_val = pgm_read_dword(&sin_table[45]); โ โ
* โ โ float result = sin_val / 65536.0f; // Scale back to float range โ โ
