Is a suppurt of freescale cortex m4 thinkable ???

Hello, I know my question is a little bit off-topic. Your product support a bunch of boards and my experience with the mbed board are really good. I also understand that the support of mc's from one manufacturer is easier as supporting multible manufacturers. On the other side there are really inter...

Re: optimized Serial.PutChar ?

Thank you for this hint. I'm using TxReady in combination with a Ring buffer based Fifo to implement my background communication. It works very well.


Best regards

optimized Serial.PutChar ?

Hi, I'm thinking about a simple background communication. In this scenario one character per main loop cycle should be send if a char is in the background send buffer ( the scenario is not the same as a buffered UART). I have implemented one version with the standard implementation of the MODULE Ser...

Re: debugging in the case of hardware faults

Hi, Thank you for your explanation ! I think it would be good to include it in the documentation. Your explanation related to the identification of the line which raise the hardware fault leed me to the idea if it would be a good idea to integrate this task into the IDE. It is not a big deal to make...

Re: problems with PWM

Hi,

Thank you for your quick response !
Before your response I was also looking to the PWMBase address in MCU.mod but could not detect the difference. It seems that sometimes I need glasses :))

Now my PWM test program works.


Best regards

debugging in the case of hardware faults

Hi, this Topic is relate to the topic [http://www.astrobe.com/forum/viewtopic.php?f=3&t=416]"problems with PWM[/url]". I create this additional topic to address the question what can we do if hardware faults occurs. Are there debugging strategies related to oberon and Cortex M3 based boards ? The on...

problems with PWM

Hi, I hope evrybody had a Merry Christmas and I wish evrybody a new Happy New Year ! In the last weeks I wrote some small test programs (extending the ADC for multible channels, implement a interrupt generating GPIO for input detection ..). I use mbed LPC1768. After that I'm trying to implement prog...

Re: is support for cortex M4 based boards possible / planned

LPC4357 may be used as a dual-core devices, but also as a device with a clock frequency of 204 MHz and FLASH 1024 KB. LPC4088 has a frequency of 120 and FLASH 512. M0, if necessary, can be programmed by other means. I agree with that. From my point of view it would be a big deal to support LPC 43xx...

CAN Support

Hi,

Are there any plans to support CAN interface as a standard module ?
What is the best way to implement a CAN interface. Does exist oberon oriented source code examples or should I try to translate C Code examples to Oberon-7 ?
Any hint is appreciated.

Kind regards,


Andreas

Re: is support for cortex M4 based boards possible / planned

Hi, Thank you for your fast response ! Do you have a particular development board in mind? Not yet. Is there anything in particular that you are hoping to do with a Cortex-M4 board that you cannot currently do with a Cortex-M3? I think for hard realtime motion control applications the DSP inside a C...
