Hello, I am implementing bulk transfer on the 1161 USB chip. This is the first time I'm doing low level programming (USB device)so please be gentle :) I have a few questions about the concept of USB bulk transfer. I read the documentation supplied by Philips but I cannot fully understand some parts. What is the difference if I assign the Bulk In and Bulk Out on different endpoints? H...

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...

Hi everybody, The LPC2000 forum on Yahoo http://groups.yahoo.com/group/lpc2000/ had a posting today that I consider a huge step towards having 32-bit micros in almost all applications. An ARM7 device running a stunning 70 MHz starting at $1.47! It has strong communication features such as two 16550 compatible UARTS, 1 SPI, 1 SSP, 2 I2C, 8-channel 10-bit ADC and a Real Time Clock that can b...

Hi, I'm trying to determine the cheapest possible way to add host-side USB (1.x) to an existing embedded system. So far, the only way I've found is to use a high-end 32-bit microcontroller. Are there simple (i.e. non-PCI-hugely-integrated-monster parts) chips that work for host side like the Philips USBDxx series works for device side? I've not found any yet...

We have developed a prototype board and software for the PC to program and test code for the Philips 89LPC901FN (8 pin DIP). Currently it only works with the 901 DIP because we think that will be the easiest chip to prototype circuits with for possible novices. The 901 does not have a hardware UART but can be bit banged. It uses a second 901 to talk to the program via serial port, (bit ...

Hi Group, We are using CS8900A 5V version and it is interfaced to Philips 89C51RD2 in *8-bit* mode - No Interrupts. CS8900A reads/writes registers, transmits and receives packets continuously (works very fine) for few minutes, say 1-2 minutes and then suddenly stops responding. If I try reading any registers at this *moment* it reads 0x00000000, stops transmitting and receiving. If I...

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 ...
