AIS4 transplan my AIS coding from arduino to ESP32

ESP32 is a cheap chip with lot of varities of boards, and good support with community.
The integration is very high:
2 MCU + wifi+BLE on chip, and you can easily find boards with OLED, Lora, beside the serial0 used by bootloader, there are still serial1 and 2 for other connections.
The integrated touch sensor could be used for water prove buttons.

So, I decided to put this program on ESP32 for easier development.

The first trouble I came across is the uart pin selection.
ESP32 has a pin muxing matrix function, so you can almost use any pin you want for your selected function. But there are some pins we should avoid:
Internal connection to flash.
pin related to bootloader.

So, I end up with connecting my GPS on serial1 pin4 as Rx, few modification on serial stuff, code works great...I love arduino!!

https://github.com/Ldsrc2008/AIS-encode-arduino/tree/master/GPS_ESP32_Uart104_make_AIS_sentence

Now I wish to add OLED display for :
  1. GPS status: 3D fix (or locationavailable?), sat Nr, Hdop
  2. GPS Lat, Lon
  3. GPS COG, SOG
  4. and maybe later heading, heeling angle
which may need to be seperated into few pages, I wish to do this with ESP32 touch sensor.
Again, I need to check the pins
There are several lib for 1306 OLED I have installed the following 2, they are all included in arduino IDE that I used V1.8.5:
  1. /esp8266-oled-ssd1306
    Driver for the SSD1306 and SH1106 based 128x64 pixel OLED display running on the Arduino/ESP8266 platform https://blog.squix.org/
  2. the Adafruit SSD1306 library repository on GitHub
the first one works out of box, I remember I used the 2nd one on  a 1280*64OLED on arduino, and it's noted that the reset pin need to re-assigned with ESP, I don't know where is the reset pin of the board. So, this time I will stick on the first one.

With squix's blog has also some thing interest me a lot...

But...this wemos esp32 OLED board I2C pins are on GPIO 5 and 4 for data and clock respectively.So, I need to move my GPS pin...

So, In short  GPIO0,1,2,3 are not usable, GPIO12 either(unless you will unplug the thing that you connected during boot up or loading code)

it should be straight forward with the library. then next concern is to see how to make the the page control and size of font and OLED.

I got problem if I wish to add touch sensor....after looking in to all the stuff I have, I need to move again:
Rx1=IO13
TX1=IO16
Rx2=IO25
TX2=IO26
then I could leave me
touch6=IO14
touch3=IO15

The code could work without issue on boot nor download

Heltec ESP32+OLED+Lora, hardware testing

圖片
you can easily find some good boards from china, but most of them lack of accurate document... Hrere is an example; https://hackaday.io/project/26991-esp32-board-wifi-lora-32 the board looks good with lora and a 128x64 OLED, but the IIC and reset connection is important, since pin can be muxing easily, so every board could be different. pinMode(16,OUTPUT);  digitalWrite(16, LOW); // set GPIO16 low to reset OLED  delay(50);  digitalWrite(16, HIGH); // while OLED is running, must set GPIO16 to high  and, if needed, edit your Wire.begin() to Wire.begin(4,15); (4 = SDA 15 SCL)  i tested it with the Adafruit SSD1306 and the Acrobotics SSD1306 Librarys  both work.  Display size is 128x64 There are discussions on these boards on TＴＮ as a LORA node..or maybee single ch gateway? Heltec has a git :  https://github.com/Heltec-Aaron-Lee And there is another copy call TTGO https://de.aliexpress.com/item/TTGO-LORA32-868-915-Mhz-S...

micro SD card for ESP32, on lolin32 with OLED and heltec 32 lora oled

圖片
I have purchased 2 micro SD card holder for my esp project. First I would like to test with heltec esp32 lora oled module. this module uses: sck=05 MISO=19 MOSI=27 SS(lora)=18, then I assigned 21 for sd SS and there is a lib in esp32-arduino, which use SS default at 5 I took the example and use SD.begin(21), but I alway get the error: entry 0x40078a9c Card Mount Failed But I do saw once that it read out the sd card type and volume. Not sure it's the issue of lora sd card swithing, or it just can't work. The other esp32 card I have is an wemos esp32 oled, it did not leave me too much pins, I need to find out how to connect sd to it. But I have wemos D1 mini esp8266 on hand, and connect it as:  * The WeMos Micro SD Shield uses:  * D5, D6, D7, D8, 3V3 and G  *  * The shield uses SPI bus pins:  * D5 = CLK  * D6 = MISO  * D7 = MOSI  * D8 = CS It's not working with the example in the arduino IDE 1.8.5, which m...

AIS0. understanding AIS NMEA 0183: How it's coded

For my boat tracking system, I found out that using AIS format seems to be a good idea, at least I don't have to worry about how to present boat data, since there are already plenty things for do this on mobile phone or PC. Here is what I read: http://catb.org/gpsd/AIVDM.html Looking into AIS NMEA0183, it has much more application then I think. Such as MOB device, epir, aid to navigation device...etc, all are included. it use the first few char to indicate the function: Table 1. AIS talker IDs !AB NMEA 4.0 Base AIS station !AD MMEA 4.0 Dependent AIS Base Station !AI Mobile AIS station !AN NMEA 4.0 Aid to Navigation AIS station !AR NMEA 4.0 AIS Receiving Station !AS NMEA 4.0 Limited Base Station !AT NMEA 4.0 AIS Transmitting Station !AX NMEA 4.0 Repeater AIS station !BS Base AIS station (deprecated in NMEA 4.0) !SA NMEA 4.0 Physical Shore AIS Station It can also be used between device on boat for message communication, AIVDO The...
