Jim, I recommend checking the pin definitions in your User_Setup.h file (TFT_eSPI library) against the pins used on the PCB. If the definitions don't match you won't see any display. John's PCB uses a

There are a few small updates to the NTP clock. The code now supports ESP32 and ESP8266 microcontrollers. A PCB using the ESP8266 was designed which supports 2.2, 2.8, and 3.2" displays. And a builder

Yes, even the tiny ESP8266 "D1 mini" will work. Bruce w8bh.net

Paul, Yes, it works quite nicely with ESP8266. Only one small code change is needed. Change the 3rd line from "#include <WiFi.h>" to "#include <ESP8266WiFi.h>" You will also need to modify User_Setup.

Art, In the file, https://github.com/bhall66/NTP-clock/blob/main/NTP_DualClock/NTP_DualClock.ino Lines 172 and 174 call the routine showTimeDate(), the last two parameters of which are the x,y coordin

Timm, I will try to help you off-list. Bruce w8bh.net

Kevin, Go to http://w8bh.net/NTP_DualClock.pdf You should see a table at the top of page 3. Bruce w8bh.net

Sorry for the late reply. Here is an NTP-clock using the ESP32: Description: http://w8bh.net/NTP_DualClock.pdf Source Code: https://github.com/bhall66/NTP-clock and a few other clocks are here: http:/

I said you might need to shorten it because headers come in different sizes. Glad to hear yours fits. Bruce w8bh.net

You can do it, but you have to solder the male headers for your Blue Pill with the pins facing up. And you might also need to shorten the Boot header. Bruce w8bh.net

Hi Tom, That is a good video. Andreas does great work, doesn't he? Last August I corresponded with Dan (of dan@...) about his Arduiono package for the STM32. He indicated that his package automa

Goober, Brian: Great catch, thanks! You could also change the line question to: int c = '!' + random(sizeof(morse)); This line does not take any more code space but removes the literal '58'. If someon

All, I have a small update for the ESP32 Morse Code Tutor. A new pcb has been created: 1. Smaller size (about 10 x 10 cm): only $2 for 5 boards at JLCPCB. 2. Supports larger displays (2.7" and 3.2") 3

All, I have a few more updates for the Morse Code Tutor. - Iambic Mode A, Iambic Mode B, and straight key. - New Head-Copy feature. - Callsign customization at runtime. - Small bug fix for display of

Hello Jim, I updated the gerbers on 10/3/19 to accommodate speakers with the larger 1 mm pins. Adafruit speakers with 0.7 mm pins will fit on the older boards. The error was mine; I did not realize th

All, Following in Dave KI4PSR's footsteps, I designed another PCB for the Morse Code Tutor. To keep costs down I am not selling the PCB. Instead, I am publishing the gerbers so that you can obtain you

Fred, The short answer is Yes. On GitHub you have access to all previous versions of the code. Bruce w8bh.net

I updated source code for Morse Code Tutor. Changes: 1) I adopted the pin assignments originally used by Jack. 2) New pin assignments are compatible with the PCB by KI4PSR 3) Straight key input is now

Good morning Dave, the short answer is no, it does not. But I am curious what they would like to do with the straight key. For instance, are they just interested in hearing and practicing their sendin
