Part Number: TM4C129ENCPDT
Tool/software: Code Composer Studio
Hi,
We are using TM4C129ENCPDT with CY14B108K NVRAM. We have made a PCB prototype interfacing the controller and the NVRAM IC. The connections are made according to the Host Bus Mode…
Part Number: TM4C1294NCPDT Hello, I want to send data from an external SD-RAM, which is connected to the EPI interface, into the SPI FIFO buffer. Now you can access the SDRAM directly by its address range if it is addressed correctly via the EPI API and…
Part Number: TM4C1294NCPDT Hello,
When setting up the TM4C129 for EPI, several code examples state the following ...
// // Configure the GPIO pins for EPI mode. All the EPI pins require 8mA // drive strength in push-pull operation. This step also…
Part Number: MSP432E411Y-BGAEVM Other Parts Discussed in Thread: MSP432E401Y , MSP432E411Y Tool/software: Code Composer Studio Hello,
I am trying to use the predefined pattern to control an external DAC. Please see the code attached. The predefined…

Hi,
My customer is using EPI Hostbus 16bit mode. when they are writing, CS signal and WRn signal falls simultanously. However, when they are reading, RDn signal falls after one cycle CS falls. Is this normal? What sholud…
Part Number: MSP432E401Y Hello,
We are using the EPI on the MSP432 to communicate with an external FPGA in general purpose mode. The FPGA has a special register that is connected to the output of a FIFO buffer, to be used for transferring large files…
Part Number: TM4C1290NCPDT Tool/software: Code Composer Studio Hello,
I've been trying to get the EPI on the TM4C129 working in muxed 8bit host bus mode but having zero luck. Snippets of the code are below, please let me know what I'm doing wrong. On…
Tool/software: TI-RTOS Hello,
I am looking for any solution to detect the presence of the EPI SDRAM. I put the following code to a device where the RAM is not present and I can not upload any new code into the target. When I hit the debug the CCS says…
Part Number: TM4C1294NCPDT Hi Everyone I would like to use the EPI of the TM4C1294NCPDT in General-Purpose Mode. I am confused why the iRDY Input Signal for stalling reads, is not implemented anymore (as it was on the Stellaris LM3S9D90). On the Data…
