I have been trying to write on AT25M02 (EEPROM memory SPI compaible interface in mode 0 and mode 3) but when i read the address memory return a "0", i don't know if I'm wrongly configuring the SPI module. AT24C16A is an I2C compatible EEPROM IC manufactured by ATMEL. When i am try to store the data in Winbond chip it is working fine i can able to read and write data in winbond chip but if i want to overwrite the new data in same address it is not overwrite and it is giving the old data that is new data is not written in same memory. With plug-and-play USB connectivity, the NI USB-8451 is a portable solution to communicate with consumer electronics and integrated circuits. This document describes the hardware interface between the McBSP and a SPI ROM. Thanks for you question! The functional examples that Total Phase provides with the API software package are to read, program, and erase two specific devices: AT25080A SPI EEPROM and AT24C02 I2C EEPROM, which are installed on our I2C/SPI Activity Board. , inheriting the Seiko Instruments Inc. The Pi Wedge helps access the I2C and SPI signals. The memory is accessed via a sim-ple Serial Peripheral Interface™ (SPI™) compatible serial bus. It supports high-speed programming of nearly all 24/25/93/BR90 chips.

Below is the code generated to interface properly to this Microchip EEPROM. The code that is written by the user to perform a specific task by the MCU is stored in the FPM (Flash Program Memory) of the MCU. Using Embedded Tools for I2C, SPI, and I2C/SPI Host Adapter EEPROM Activity Board Host Make the corrections to source code in line 254. 2-6 Write the bin file into SPI EEPROM of APC: – Click the “Write” button in SPI Flash menu to load xxxx~x.
