Re: Problem using Flex Full board and RS485 module

I figured out why the TX interrupt did not occur. What happened was the following: Once TX INT was disabled "after" TX completion, I needed to write a byte to U2TXREG before re-enabling the TX INT. Another problem I have is mode switch in RS485. Now my master can send bytes to slave periodically and...

Re: Problem using Flex Full board and RS485 module

I fotgot one thing: The jumpers JP2 and JP3 on the RS485 adapters are set to pos 1-2 (TXEN).

Re: Problem using Flex Full board and RS485 module

Following the instructions on the Wiki, I was able to send & receive bytes from one set of FLEX + Multibus daughter + RS485 to another set. Once tx of a packet is completed, the sender disabled TX interrupt inside the UART2 TX ISR (please see below for details). However, next time I re-enabled the T...

Re: Sample code with CAN communication

Has anyone succeeded to receive a CAN message using the code posted above? It works for "loopback" test, but I am having trouble with a two board setup, one tx and another rx. I can see the traffic on the bus using a CAN bus analyzer but the receiver never gets the messages. It seems no data is writ...

Re: Sample code with CAN communication

I put jumpers on JP1 of both CAN modules and connected CAN+ & CAN- without any resistors. However, it's not working. Please see below for my code snippet for init, send, and receive. One sender (FLEX Full+Multibus+CAN module) periodically calling Send_ECAN1() while one receiver periodically calling ...

Re: Sample code with CAN communication

With the source code from the repository, I was able to run a loopback test (JP1 on CAN module) with CAN module on top of Multibus daughter board. I was able to receive the message I sent through the DMA configuration. However, when I tried to test communication between two sets of Flex Full + Multi...

Project management between RT-Druid and MPLAB

I have several questions on project management with RT-Druid and MPLAB. I started my project by borrowing a sample RT-Druid project. Later, I added more .h and .c file in the project and started to have the following issues. 1. Though RT-Druid recognizes which files belong to the project as I list t...

GetResource() / ReleaseResource()

How can I delcare a resource in EE? I do not see the "DeclareResource()" API in the EE basic reference manual. Can I simply define it, e.g., "ResourceType S1;" ? Can I use GetResource() / ReleaseResource() pair to block the calling task (put it into a waiting state) when the resource is already occu...

Re: Sample code with CAN communication

Any updates on this topic?

Another question: Does RT_Druid include any CAN device driver for the CAN adapter module on multibus daughter board? Or, are there any CAN drivers available for FLEX platform?

Thank you,

Re: Console demo with RS232 module?

Yes. I made it work with both UART1 (#define MY_FIRST_SERIAL 0) and UART2 (#define MY_FIRST_SERIAL 1) slots. I used the RS232 module and a hyperterminal at PC. There was a warning about strlen() during compilation but it worked fine.

Thank you,

Console demo with RS232 module?

Hi, I am looking for a way to print out messages from FLEX board on a console on a Windows PC. I found a demo program using console_descriptor_t at RT-Druid C/C++ Project -> pic30 -> FLEX Demo Board -> Console demo. My question is as follows: 1. Do I need a RS232 module to use this program for such ...
