compile error unter platform.io with Arduino framework #39
Description
Activity
I have additional informations. I took a look in the code and found condition compilation.
#if defined(ARDUINO_ARCH_ESP32) && !defined(PREFER_SDFAT_LIBRARY) size_t bytesRead = file.readBytes(buffer, len); #else size_t bytesRead = file.read(buffer, len); #endifThe platform i used is a esp8266. So the define for the architecture is different. I suggest to change this part to:
#if (defined(ARDUINO_ARCH_ESP32) || defined(ARDUINO_ARCH_ESP8266)) && !defined(PREFER_SDFAT_LIBRARY) size_t bytesRead = file.readBytes(buffer, len); #else size_t bytesRead = file.read(buffer, len); #endifThis solves the problem for me.
Than you for you work and best regards
Michael BernsteinOne additional question:
Is the check for the architectuer really needed? I got the feeling, fs:File::read has on all platforms a uint8_t * as first parameter. So i thought, using readBytes should be used on all architectures.
I add this library to a project under platform.io with Arduino framework and got a error while compiling this lib:
I think, the problem can be fixed by change fs::File::read() to fs::File::readBytes() which has a "char *" as first parameter and calls read() with a typecast to "unit8:t *"
A typecast should also work.
