Hi All, Unfortunately, the plan to connect OnStep and SHC via UART has not been successful. I would like to connect OnStep 4.24 and SHC (ESP32S) via UART using TX6RX6 on the back of Teensy 4.0 as the

Hi There! After wiring, I tried rewriting Config.h and Pinmap.h of OnStep and Smarthandcontroller, but OnStep and SHC do not connect via UART. I think the syntax for rewriting Config.h is probably wro

#SHC

I notice only one error: The RJ12 connector on OnStep (Teensy4.0) has RX going to RJ12 pin 4 and TX going to RJ12 pin 3. They should be RX to RJ12 pin 3 and TX to RJ12 pin4. You want TX to RX and RX t

One of the procedures to connect OnStep and SHC via UART is summarized below. Please let me know if you found any mistakes. Connect the Teensy 4.0’s TX6, RX6 and a modular jack (Fig. 1). Finally set t

No, I pasted a copy of general purpose instructions from the Wiki. Many: Teensy3.2, Teensy4.0, Arduino M0, ESP8266, ESP32.

Thanks Drew, I forgot they changed that.

Not quite, in order to have the v2.0.2 available in the Boards Manager you must use the new URL: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json

https://github.com/hjd1964/SmartWebServer/tree/main Instructions for installing the ESP32 libraries are in the Wiki (as shown below) except you select 2.0.2 instead of 1.0.4 in the Arduino Board Manag

#SHC

Thank you for a lot of information. I was able to organize what I wanted to do. u8g2 2.31.2 was found. How can I download SHC with ESP32 libraries 2.0.2?

#SHC

I believe this accomplishes the same thing as shown in your schematic, without modifying the SHC.

#SHC

To confuse things even more... I just added a feature to the the Smart Hand Controller code (GitHub main branch.) You can now move the serial port to basically any ESP32 pins, but note that the ESP32

I want to point out, again, that the goal at the beginning of this was to have an ST4 port configured for and devoted to auto-guiding (ignores high rate guides as used for centering objects.) So that

I don't clearly understand what you are asking.

#SHC

Thank you for the information about Config.h. Before rewriting Config.h, I must check the following. Recently, I found the schematic of the Simple Smart Hand Controller. I am considering both Smart Ha

Again, I saw one issue that would definitely cause this to not work: You need to remove the second occurrence of #define SERIAL_C_BAUD_DEFAULT as OFF disables the command channel. Just delete that sec

#SHC

For persons who can't do programing of Arduino, it would be helpful if you could give me some information about Config.h for connecting OnStep and SHC via UART. I would be very grateful if you could e

#SHC

Your OnStep Config.h image shows you assigning the baud rate of 9600 to SERIAL_C_BAUD_DEFAULT... then you later you assign OFF which overrides the 9600 disabling the command channel.

#SHC

Yes, I have connected Teensy4.0’s pins 24 and 25 to ESP32S’s pins 16 and 17. By the way, GPS is connected to pins 28 and 29 of Teensy4.0. I rewrote ONSTEP and SHC Config.h as attached, but ONSTEP (Tee

Looks like "pins" 24 and 25 will be the easiest to access on the Teensy 4.0.
