i2c.reqfrom hang ?

[Oli]

for all versions ESP8266 and ESP32 works

Code: [Local Link Removed for Guests]

sub PCF8574a_read(x)
i2c.reqfrom PCF8574a_address, 1
 x = i2c.read
 i2c.end
end sub

with the ESP8266 the additional i2c.begin does not disturb, so that the samples and description work,
with the ESP32 the line is not allowed to be included.

if the PCF is connected everything works fine, as soon as the connection is interrupted or you start a program without a PCF connected the ESP will reboot,

Oli,
thanks for your feedback, I was expecting this behavior for the ESP8266 .... I'll update the documentation.

Could you confirm that the reboot happens only on the ESP8266 ?
