Yes - I understand what you want to do. If you can explain why you want to use it a at a slower speed then we might be able to tell you how you can achieve what you are trying to do.

Re: Serial port settings

The serial port setting of the Astrobe terminal is fixed at 38400 baud to match the settings used in the Astrobe runtime library error trapping routines. What are you hoping to use the Astrobe terminal with by using a 9600 baud connection?

Re: External Interrupt3 of LPC1769

You need to set the bit in the Clear register to clear the interrupt.

Re: External Interrupt3 of LPC1769

I thought that to clear the interrupt you had to set Bit 11 in the IO2IntClr register (Section 9.5.6.11)?

Re: External Interrupt3 of LPC1769

Make sure you clear the interrupt before returning from the interrupt handler. Refer to the NXP LPC176x/5x User manual (UM10360) for more information.

Re: Image Downloading to target lpc1769

No. This is as designed, to avoid the need to have to enter the path name of the executable when uploading (sic) to the target. Typically you want to upload the current application you are working on. If you want to upload a different application then you need to open the source code of its main mod...

Re: Changing the embedded OS memory map

Good question1 Yes, you could quite easily reduce the amount of BRAM used by Oberon. NOTE : The following information applies to the Arty implementation but a similar technique can be used for other boards but the details would be slightly different. If you run Test.Watch at startup time you will se...

Re: RISC5 Oberon on the $99 Arty Artix 7 FPGA Development Bo

Yes - that is the board to buy. You will also need: A MicroSD card socket / breakout board A means of connecting the card MicroSD socket to the Arty. A 2GB or higher MicroSDHC card Software to copy our Embedded Project Oberon disk image to the MicroSDHC card. A Micro USB cable to connect the USB por...

Colour Graphics on a 1.8" TFT Display

I have now ported our AutoCAD slide viewer from ARM Oberon to RISC5 Oberon running on the Digilent Arty board with an AdaFruit 1.8" 128x160 TFT display connected via SPI1 to one of Arty's PCOM sockets: slide.jpg The file sizes of each of the compiled modules ( in bytes! ) that form part of the appli...
