A Slightly Better NTP Client for the ESP32 (ESPWROOM32) on macOS Catalina
Currently have two ESP8266 modules testing some Blynk apps, whereI'm not so happy with the Blynk business model for developers, but that's another story.
So, with two of my ESP8266s currently "busy", I decided to work on the ESP32, and in particular the ESPWROOM32.
I installed the recommended Arduino ESP32 libs in my Arduino IDE running the 10.15.2 version of Catalina, and I got mixed results with different board managers. In a nutshell, I was having trouble getting anything more than "Hello World" to work.
So, I wrangled with this for a few hours, trying myriad ESP32 board managers; and finally got it working, by following the manual ESP32 for macOS instructions here:
This install code worked flawlessly for me:
and I was able to get my "A Slightly Better NTP Client for the ESP32" code working on this ESPWROOM32 using the NodeMCU-32S board manager. No other Arduino ESP32 board manager gave me better results; and I was able to get this NTP client working on the this version of the ESP32:
... and it worked!
But I think I will take a diversion from the ESP modules play around with my RFID module, the RFID-522, and see if I can read some RFID devices I have on my keychain and then attempt to clone them with this $1 to $2 USD RFID board.
Was not really happy with the NTP clients for the ESP8266 because, after a few years of game engine programming, I am not a fan of a lot of code and delays in the main loop, so here is a "slightly better NTP client" for the ESP8266.
In a nutshell, instead of having a delay in the main loop as a... (1 Reply)

Just a quick note for macOS users.
I just installed (and removed) Parallels Desktop 15 Edition on my MacPro (2013) with 64GB memory and 12-cores, which is running the latest version of macOS Catalina as of this post. The reason for this install was to test some RIGOL test gear software which... (6 Replies)
On the NI-VISA boards there has been some frustration where folks cannot get NI-VISA to work on macOS Catalina because Catalina (macOS 10.15.x) is "not supported" by NI-VISA (for many months, it seems). Currently, the README shows:
NI-VISA 19.0 for macOS supports the following platforms:

Sadly, I have turned off my access to the Apple Developers Beta program after installing macOS 10.15 Catalina a few days ago.
After the install, I rebooted by MacBook Air and it "hard froze" and we were heading out of town so I grabbed a backup MBA running Mojave.
Then, after getting back at... (10 Replies)
Interestingly Apple has decided to switch the default shell for new users from bash to zsh in MacOS Catalina (10.15)

Hi,
I have two ntp servers in my cluster and I want all the nodes in my cluster to sync with either of the ntp servers or just one. Unfortunately it keep rotating the sync, between my ntp server 1, ntp server 2 and local. Is there anyway I can change the sync to avoid local?

Hi, I am trying to configure NTP client on my Solaris server, but I am getting error like:

All,
How do you set a Solaris 9 server which received ntp updates from a ntp server to broadcast them on a local subnet. I have created a /etc/inet/ntp.conf file to receive the updates from a server on network and need to make this server become like a ntp relay from the main server.
Any... (1 Reply)
