Whilst I can still get serial mice I feel their days are numbered moreso than PS/2 mice which presumable will also eventually become obsolete for USB mice. I have trawled for 8051 code for the PS/2 mouse and only found one instance which is in assembler and not for the assembler bundled with the SDCC compiler. There were some hints that there might be code on the Philips website but I can...

Hi, I am working on a prototype with the above controller in device mode. I have no problem transferring packets smaller than 64Bytes; but I am having trouble with packets larger than 64 bytes, the size of the end point FIFO buffer. Currently I simply chop up the data I want to send in 64 byte chunks + any remaining bytes and then send them out by writing to the endpoint and then valida...

Hi, I am thinking about putting either eCos or ucOS into the just released Philips ARM7 LPC21xx chip. It has something like 16kB of RAM, 128kB (or 256kB depending on the part) of FLASH on-chip, with no external memory bus. Before going ahead, I would like to have a sanity check: can the porting of eCos or ucOS be done with the resources? It aims to be my hobby project. Just want to try...

Hi all, Amontec just released a new configuration of the RAVEN on the Chameleon POD. This configuration enables the use of the rtck (return clock) for all ARM -s series. In fact, the ARM7TDMI-s ( and other ARM -s ), like Philips LPC21xx, use the rtck signal to control the baudrate of the JTAG. This means you can debug software running at very low frequency, but this means too that ...

I'm interested in purchasing a demo board for an ARM7TDMI-based microcontroller (a Philips LPC2129 to be exact.) That's fine with me, it only costs ~$150. I want be able to debug it with a JTAG debugger, so ~$300 debuggers by Keil and/or Nohau come to mind. Salespeople tell me that I can't just stick the Jtag onto the demo board, but that I would also need to buy their full $2000+ develo...

Hi, I'm currently using the SAA7108AE IC from NXP (Philips) for a video decoding and encoding application. The decoding part works well so there's no problem on this side. However, I have trouble making the encoder work. The encoder part of the SAA7108AE is pretty much the same as the SAA7105 (which is an encoder only). Input to the encoder : ITU 656 stream (8 bits). 27 MHz clock Outp...
