RC ESC modification part1: general

 I have lot of RC BLDC ESC, old ones for air plane, I found they are very similar from one to each other.

In general: lot of N channel mosfet with IR2101S gate drive controlled by a atmega 8 or 8L 16AU works at 16Mhz crystal. These MCU is the same as arduino 328P but with smaller memory.

On the web, you can find some BLDC ESC projects with arduino and IR gatedrive.

It makes me wonder: 

1.can we modify it to work with arduino?

2.Or can we do some modification to change it from sensorless ESC to sensored ESC?

3.My ESCs are mostly for air plane usage, there is no reverse, could be modify to car usage or boat.

4.There is a also a arduino based FOC project, we could also modify ESC to work with?

I will start with these 2 ESC


sources I found:

example of BLDC(sensor less and sensored) with Arduino
https://simple-circuit.com/arduino-brushless-dc-motor-controller/
https://simple-circuit.com/arduino-cd-rom-brushless-motor-control/

simple FOC, it is a very well made library with good documentations.
https://www.simplefoc.com/

This article talk about dead time of gate drive(IR2103STRPBF is the same price but Vcc is 5 to 20v and has internal dead time .)

interesting thing is that you can also run a simpleFOC SW on VESC HW board

https://docs.simplefoc.com/stm32_mcu#vesc-boards-support



I plan to do these:

1. Get a clear view on the schematic of RC ESC, wires used in RC ESC, connection between 2101 and MCU
2.using arduino to control S2101 with simple FOC
3. hall sensor or other sensor supported by simple FOC to get a smoothly low speed ratation. https://docs.simplefoc.com/hall_sensors

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...
