Adafruit_FRAM_SPI rel.2.4.1 error: invalid conversion from 'const uint8_t*' to 'uint8_t*'

[pippo-75]

Hi all, using Arduino IDE 1.8.20 (NOT relevant) on Win10 (NOT relevant), selecting ESP32, Tools setting ==> Primary Debug Level: "Verbose", using this code (just the minimum to reproduce the problem):

// Adafruit_FRAM_SPI library version 2.4.1

include

// instantiate the SPI library defining the used SPI pins // HSPI ==> SCLK=14, MISO=12, MOSI=13, CS=15) Adafruit_FRAM_SPI myFRAM = Adafruit_FRAM_SPI(14, 12, 13, 15);

void setup() { // put your setup code here, to run once: myFRAM.begin(); // }

void loop() { // put your main code here, to run repeatedly: }

On Serial Monitor I am notified: Adafruit_FRAM_SPI.cpp:220:18: error: invalid conversion from 'const uint8_t' {aka 'const unsigned char'} to 'uint8_t' {aka 'unsigned char'} [-fpermissive] Adafruit_SPIDevice.h:80:23: note: initializing argument 1 of 'bool Adafruit_SPIDevice::write(uint8_t, size_t, uint8_t, size_t)'

Obviously, after removing that -const- from the two files, the whole thing is compiled without errors / warnings.

Just to clarify: the version 2.4.0 of the library does not report any type of error/warning.

which library version of Adafruit BusIO that you have, if it is not latest (as of now 1.11.6), then update it and try again.

Yes, you are right - I was using 1.11.1 and after the update the error disappeared. I didn't imagine having to update them together. Thanks for the 'news' and have a nice day.

Thanks for your confirmation. Closed now.
