I need to read and write data to an EEPROM connected by I2C on a RaspberryPi4. The I2C channel is found in /dev as i2c-1:
$ ll /dev/i2* crw-rw---- 1 root i2c 89, 1 2019-02-14 11:12 /dev/i2c-1 In this channel the EEPROM CAT24C128 is at address 0x50 The data on the device is organized as 256 pages of 64 bytes data each AFAIU. I can check the EEPROM using i2c-tools, which I have installed, but I am unsure if the read is correct... Question: Can I use Linux file system commands to read/write the data on the i2c EEPROM memory device and if so how from fpc? I have installed the current versions of Lazarus and Fpc on the RPi4 itself. -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
