Hello guys, I'm using a MKL33Z64VLH4 microcontroller and I need to write data to an eeprom i2C memory, but I'm having trouble understanding how to use the MCUXpresso v11.3.1 library, if anyone can help me, I'll be very grateful! Model of eeprom memory (M24M01-RN6T...
The eeprom driver for spi is used rather than the spi-dev driver as it knows the details of SPI eeproms and it interfaces to the sysfs filesystem to allow userspace interaction. We actually do use the dev interface of i2c to read the eeprom contents and this is similar to what you're...
Eeprom: Atmel AT24C256C (256kbits) Environment: IAR Embedded Workbench TivaWare_C_Series-2.1.0.12573 Under normal conditions I can write to and read from the EEPROM. I am trying to handle some exceptions now. One of ...
If you will take the time to study, you'll get a really good hand on using I2C with the 24LC512 (64K EEPROM that many of us use with the Propeller). You can even experiment with the EEPROM you have -- just make sure you don't write to an address where program data is being sto...

if (hid_write(device, buf, 3) == -1) { puts("Error writing bytes to device!"); hid_close(device); return -1; } if (hid_read_timeout(device, buf, 2, 100) == -1) { puts("Error reading bytes to device!"); hid_close(device); return -1; } printf("Received bytes: %02X,...
Also, you could try to read it on U-boot. Best regards. 0 Kudos Reply 11-27-2023 04:13 PM 575 Views JohnKlug Senior Contributor I Looks like it is not possible from Linux with the i2c bus running. The i2c bus is functional, and I can dump my EEPROM.The following ...
Each USBFilesystem is used the same way as the SD library. You can call open() to access files, remove() to delete files, and so on. The open() function returns a File instance, so it can be used with all libraries using File originally developed for the Arduino SD library. ...
Of course you can connect a (parallel) SRAM chip to any microcontroller given that it has enough I/O; but you don't want to be introducing any read/write memory functions that slows down access, and most of all this is then not seamlessly accessible through the memory map.Well, you ...
Figure 1 shows the schematic of a Microchip TechnologyPKSERIAL-I2C1 I2Cdemonstration board. This board implements the I2C bus using five different devices including an EEPROM, a temperature sensor, a 12-bit analog-to-digital converter (ADC), a 10-bit digital-to-analog converter (DAC), and an...
