Testing as much memory devices as possible

[sosandroid]

I need some help to test the memory devices as I do not have all of them.

The strategy:

• Verifying the device has / has not the Device IDs feature
• Testing the proper adressing scheme by using Manual Mode example
• If device has device IDs feature, check if this is recognized by the lib to set it up automatically.
• Additionnal testing with all the methods of the lib.

Thank you for your help. Fell free to leave your results here

works for MB85RC16V :-)
thx for the hard work :-D

initialized as: FRAM_MB85RC_I2C fram(MB85RC_ADDRESS_A000, true, /* WP */ A7, 16 /* kb */);

I just tested the library on the FM24C64B - works great!

No device ID, but initialized with the correct chip density (64) and all was good.

W10 + CCSv7+ Energia18 + MSP432 LaunchPad + MB85RC256V breakout from Adafruit +v1.2 libray works after a few minor mods:

1. Due to a compiler error, had to modify the line taken from an example:
   FRAM_MB85RC_I2C mymemory(); to
   FRAM_MB85RC_I2C mymemory;

2. Need to edit this line in getDeviceIDs (this issue is talked about elsewhere online)
   result = Wire.endTransmission(false); and replace with
   result = ERROR_0;

3. When doing timing tests, needed to add some Serial.flush() lines before/after timing sections to get stability with results. I2C with Serial terminal-type output has caused me some issues elsewhere...I think this is related.

Timing Info:
100 bytes array write: 1952 us
100 bytes array read: 2103 us

Tested the Cypress FM24CL64B on a Particle Photon, works great in manual mode, initialized as:
FRAM_MB85RC_I2C memory(0x50, false, 13, 64);

test FM24C04B on Arduino stm32. Tests work fine.

Thanks

Tested FUJITSU MB85RC04V, on Arduino Uno. Seems to work perfectly! Thanks for this great library.

Tested Cypress FM24CL04B (4k) on ESP8266 12e (NodeMCU) and works fine.

(When reading all memory 1 byte at a time the ESP soft reset after around 220 reads which was probably due to heap/stack issues. Reading 8 byte arrays works fine.)

I tested the Cypress FM24CL16B with an ESP32. Works like a charm.
