[TriEmbed] ESP8266 Programming tip

[Pete Soper]

Does ESP-12E support JTAG debugging? It might be interesting to figure 
out what the crash is about (maybe there isn't actually a task scheduler 
present and if you don't "yield" back you've violated the API 
contract?). But you've stuck with the pragmatic approach, John. Thanks 
for the tip.

Getting  SparkFun "Micromod" boards with ESP32 and ESP8266 (no idea what 
flavors) and the "All the Pins" carrier board today. But these go on the 
shelf as I wait for the RP2040 Micromod board, and my stack is pushed 
anyway. Particle Land, here I come. :-)

Using the Ticker library to schedule a task, I quickly found out that the task better be quick or it will crash the program. To define quick, my task was maybe 25ms, which was enough to crash the program. To get around this I found on the web a quick tip that made alot of sense. Just use the Ticker task to flip a bool and then have an if statement run the task and reset the bool.
