I'm investigating the best approach and library to read animated GIFs from a micro-SD card and play them on a large LED pixel matrix. This will be done on a Teensy 4.0 that is performing other time-critical tasks, so...
Hi! I hope you don't mind if I ask a few more questions:
1. When testing the WebServerAP example, I see that server.handleClient() consumes about 2.5 seconds of CPU time (in two ~1.2 second chunks) each time that the...
The WiFiWebServer that you referenced was written by the same guy as the ESP8266_AT_WebServer that I"m currently using. They seem to have similar capabilities, but there must be some critical difference that I'm not...
OK, I see what you're doing. A bit strange, but I'll come back to that in a minute.
micros() is a free-running counter that isn't (I don't think) guaranteed to start at zero. It rolls over every 2^32 microseconds...
Well, I'll go out on limb here:
1. elapsedMicros() and micros() are different, but in any case I don't see any calls to micros(). elapsedMillis() is probably a better choice.
2. In the lower code, you define...
Can anyone recommend a web server that will run on a Teensy 4.0 using an ESP-01 (ESP8266) wifi module? I want to implement some simple remote control panel functionality, and it doesn't need to be very fancy. It must...
upload_protocol = teensy-cli
Many thanks, kind stranger! That worked like a charm! Uploaded a large-ish program 20 times, and it was blazing fast every time.
So it looks like there may be an issue with the...
A little more info. After I rebooting my Mac, I no get the "An error occurred while uploading..." message. For the first ~8 uploads everything was very quick, but after that it started to bog down again. So basically...
Thanks for the quick response, Paul! I haven't used the Arduino IDE in a long time, but I fired it up and tried it with the Blink example sketch. (It would take a while to translate my multi-file program back to that...
I've been using the Teensy 4.0 for several years as part of an LED controller for outdoor art installations (like this one). I've had some challenges for sure, but all were eventually overcome, often with help from this...
Yes, it seems like we're experiencing the same issue. I think I'll start a new thread about this, since the responses here are mostly about the SD library compatibility issue. I've been using PlatformIO for a few years,...
I've been having similar issues with PlatformIO for a few months. I posted about this twice on the PlatformIO forum (most recent post, original post), but haven't been able to get a resolution. My current workaround...
OK! Now I get:
Starting WebServerAP on TEENSY 4.0 with ESP8266-AT & ESP8266_AT_WebServer Library
ESP8266_AT_WebServer v1.6.0
Use ES8266-AT Command
WiFi shield init done
Attempting to start AP with SSID = EFD_NET...
Thanks very much! I was just browsing through some of the other examples, and I noticed this:
// TODO, WizFi360 can't use crashing localIP()
So maybe I was on the right track. I'll try v1.6.0 and let you know how...
This is exactly what I've been looking for! I'm using a Teensy 4.0 with the Ai-Thinker ESP-01 WIFi shield. I was able to install and compile the library and the WebServerAP example with no problems (using PlatformIO +...
