Other Parts Discussed in Thread: HALCOGEN
Hi,
Customer want to connect W25Q128JV external EEPROM to TMS570LS1224, please see details below.
"Hello, I want to connect W25Q128JV external EEPROM to TMS570LS1224. i am using MibSPI3 for SPI communication. In Halcogen in MibSPi3 tab i have enabled master mode, set baudrate, charlength is set to 8 . In data Transfer tab i have selected CS0 and word length is set to 3. I am able to generate 24 bit word but after connecting to EEPROm i am not getting expected values. Below is the code i am using
/** @file sys_main.c
* @brief Application main file
* @date 11-Dec-2018
* @version 04.07.01
*
* This file contains the program to successfully run 24 bit SPI Data for ADC or DAC,
