Other Parts Discussed in Thread: EK-LM3S8962
Dear Sir/Madam,
I am part of a group of students that are building a racecar for a school project. In this project I am doing the Data Acquisition, which means putting data on and reading from the CAN-bus. To do this, I (we) bought 2 EKC-LM4F232 evaluation kits.
We build a small test environment with these 2 controllers. The controllers use Port B, pin 4 and 5 as CAN0RX / CAN0TX. These pins are connected to a MAX13050 to simulate a CAN bus. This controllers converts the Tx and Rx from the controller into CAN high and low. This CAN signal is send to another MAX13050 to convert it back to Tx and Rx and send it to the other controller.
One of them, let's call it "CAN SEND" has to put data on the BUS. Thanks to previous posts on this forum I found a way to make it work, so this works perfectly.
The problem is "CAN READ". We tested the signal at both ends and they are the same, so the signal at CAN SEND is exactly the same as the signal at CAN READ, but it doesn't generate an interrupt. This cause the software to do nothing.
As you can probably see, I added UART for debugging purposes. The code will be posted in the next message.
Thank you in advance for your time.
