Dear all, I am trying to send some datas through the COM1 of the MOD5270. When I use an infinite loop to send these datas, I have no problem. But when I tried...
Dear all, Does anybody here have pin class files for 5282? I couldn't find them anywhere in the \nburn after installing the 1.98 version. (I found those for...
Can anyone point me twds instructions/tutorial for debugging 5213s under Eclipse 2.0 Beta? The Netburner (eclipse) help files seem to suggest debugging in the...
Dzung, You need to download the latest set of development tools (1.99 beta 5) from the netburner site. From the Support menu, choose Support Login. If you have...
Hello, I was wondering if it is possible to adjust the watchdog timeout after the watchdog has been enabled in the monitor program, also does anyone know which...
A few weeks ago there was some discussion on a high resolution timer for the 5282. If you are willing to use one of the DMA timers it's a 32 bit timer ...
There has been some discussion regarding higher resolution timers. The solution seems to be to use one of the PITs to generate an interrupt every milli-second...
Hello, The watchdog timer that is used is the Watchdog Timer Module located in chapter 18 of the MCF5282 user manual. When it is enabled in the monitor the...
I changed the system baud to 600 on the board via Shift-A and "Setup" and now have no communiction when sending new application via DEV C++ IDE or when using...
Hello, I have been searching through the archives but havent found what I am looking for.... I want to implement the Modbus protocol on a MOD5270, on serial ...
Hi Jason, The 5213 has SPI and I2C serial buses, so you can add external storage (EEPROM, Flash, SD/MMC) to your own designs via either of those. I think the...
Hi Michael, I'm using 5213, not 5270, but I'm guessing the UART support is the same. NetBurner provides two modes for serial comm, one polled and one interrupt...
We have looked at adding the file system to the MOD5213. The big problem is RAM the 5213 only has 32K of ram, the file system as shipped for the other modules...
Hi Paul, What is FTF, and is there any chance we could get a preview of the actual pinout of the 5234-based 40-pin module? We're designing a 5213- based device...
Joe, Thanks for your detailed input. We also have worked with many systems using Modbus RTU. Our primary use is for our main controller to be a Modbus slave,...
Hi Michael, If you set up a free-running input capture or dma timer, and you check the RX queue frequently enough, you might be able to get away without any...
Question: How can I reduce the overhead of my interrupt routine? I am using the INTERRUPT macro. When I look at the assembly output of the compiler, there is...
1 kHz should be no problem whatsoever. My recommendation would be to try doing things without going around the OS. You shouldn't run into any problems until...
... If you've got a sound card in your computer, you can use "Visual Analyzer" for a scope: It's freeware you can get from: http://www.sillanumsoft.com/ Works...
Clarification: While the update frequency needs to be 1kHz, the resulting interupt frequency for 8-bit resolution is 2^8 * 1kHz or 256kHz since I am doing bit...
Hi, I have seen many low cost multi-meters (<$40 at fry's)that have frequency measurement up to 10MHz. These will not provide the same accuracy as an...
Thank you for the feed back. I will definitely take a look at that platform when it comes out. In the mean time, I will keep moving alon with the 5282 which...
Dev-C++ is consumming 100% of the CPU. I can not get control of the IDE, that I have to close it and restart it. I am running Windows XP, Professional with SP2...
If you are not using the RTOS then (no posts etc from inside the code) Then you don't need the overhead. Try this... extern "C" {void BAM_ISR(); void...
Hi Larry, 16 UART channels? Like in 16 rs232 ports? Because I have been looking for more UARTS for a long time, most of our projects uses mostly RS232 for...
... Well, they won't be RS-232 ports unless you add RS-232 drivers or receivers! ;-) I've used the TPU UARTs on the 68332 for quite some time, and they can...
Well, they won't be RS232, but there will be UARTS ;-) I supply the RS232 hardware driver if that is necessary, but the possibility to add many UARTS is...
Another trick is to use one of these on the SPI system for every two 232 comm channels you need. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2052 Be advised...
I've successfully used a PIT timer and GPIO to bit bang a serial interface a low baud rates (2400 baud) The PIT timer runs at 3 or 5 times the baud rate and...
