Hello and welcome back to a project log!

I would first thank you all for following me in this project and huge thanks to Arsenijs Picugins who made an article about RS485 which is very well documented

Ok so what's new?

Well there is 3 chapters:

1. 6 hours of debugging can save you 5 minutes of reading documentation
2. The camera, the keypad and the computer
3. Arduino administration is simpler than France one

               6 hours of debugging can save you 5 minutes of reading documentation

Ok so to resume, the lib need to know which command we are sending to correctly parse the input data (e.g: if the command is SET_PAN , the lib must compute the given angle to hex values to transmit)

The solution: have a list with every special case!

const byte CMND1[5] PROGMEM = {FOCUS_N, IRIS_O, IRIS_C, OFF, ON}; //List of all commands that go on the byte3; a list with command 2 is not required, a bit of logic please
const byte DATA1[2] PROGMEM = {PAN_L, PAN_R}; //List of all commands that use ONLY the DATA1 for data pass

const byte SETPOS[3] PROGMEM = {SET_PAN, SET_TILT, SET_ZOOM}; //List of all command that require an MSB and LSB

const byte DATA_BOTH[5] PROGMEM= {PAN_L_TILT_D, PAN_L_TILT_U, PAN_R_TILT_D, PAN_R_TILT_U, WRITE_CHAR};//List of all commands that use the DATA1 and DATA2 for data pass (excluding the SETPOS' commands)

const byte RESP_CMND[3] PROGMEM = {RESP_PAN, RESP_TILT, RESP_ZOOM}; 

const byte QUERY_CMND[3] PROGMEM = {QUERY_PAN, QUERY_TILT, QUERY_ZOOM}; 

const byte PRESET_CMND[3] PROGMEM= {SET_PRESET, CLR_PRESET, GOTO_PRESET}; //will I use it?

The problem: Getting a value of progmem's flash isn't what it is.

If I want to compare the Command PAN_L to DATA1, I can't use a loop with DATA1[i] (with i incrementing)

why? Because progmem is maintained by a library: pgmspace.h (more on the arduino refenrece)

The solution: After reading a bit of documentation, you actually need to do this:  

pgm_read_byte(&DATA1[i]) //(Demo purpose not in the lib)

 While Intellisense keeps throwing error because it's a bit dumb (don't worry I fixed)Ok problem fixed

                              The camera, the keypad and the computer

I swear the title is not a Clint Eastwood reference O_O

What do we do with a functionning library, we test it!

I had keypad laying around my place so I plugged him in the esp and onto the testing and good news!

The 2 modules that generates RS485 works with the 2 mains architectures (avr and esp32)

Ok little demo video right there /\

                         Arduino administration is simpler than France one

With the library completed ( I strongly suggest you to see the github repo, there are new examples, etc)

I updated the library.properties and the created keywords to create style coloring:

So with this and that next step, uploading it to the arduino library manager (again thx because the documentation is really great)

A few hour later:
Well now you can download it from the library manager ! (it's so coool)

Well with this project log finished, until next time!!!
