Hello I have to connect USB devices to my EZ-Kit BF533, and I'm searching USB chip to interface with BF533. The goal is the BF533 is the master and I'm not working with a PC, (BF533 must be seen as the PC) so my chip must work as master. Does anybody has experience or entries? Does somebody know SL811HS from Cypress? Thank's in advance |

Hello I've have problem to configure ADV7183, in order to manage PPI transfer. It works fine the first time : Configure Flash Reset ADV Configure DMA Configure PPI Configure DMA_ISR Start DMA & PPI My goal is to catch a picture, send it on a screen (via PPI bus, using DMA) and after catch a new picture but I don't want to reset ADV7183 each time because I've to wait time to lock after reset !!!. I tried a lot of thing such using TRAQ flag of ADV, stop transfer in DMA interrupt, and enable again with ADV7183_OE, but it doesn't works. Where I'm wrong ? Does anybody can help me, any suggestions greatly appreciated. Thanks in advance Stephane |

Hello, Have your tried with FTDI chips, namely the FT245BM? It's a USB FIFO which can be memory-mapped to the DSP. I've used it attached to the External Port of an ADSP-21160M with good results. A nice advantage is the ease of use of the PC-side drivers, which can be found on the manufacturer's site: www.ftdichip.com Good luck, JaaC --- Leon Heller <> wrote: > > ----- Original Message ----- > From: "Sthane GOUEL Arbos Ingenierie" > <> > To: <> > Sent: Monday, December 08, 2003 6:03 AM > Subject: [adsp] Host USB chip with BF533 > > > > Hello > > > > I have to connect USB devices to my EZ-Kit BF533, > and I'm searching USB > > chip to interface with BF533.

C8051F320 has an USB funtion controller. It can't be used as a host.
SL811HS embedded host can be used for your application. You can also try for OTG compliant devices(EZ-OTG) which can also be used to connect peripherals to BF533. Also check for EZ-HOST devices which will act only as host.

The FTDI USB chips are very easy to use due largely to their drivers. We use them in our dspstak DSP engines. However, they are not going to work in this situation since they are USB peripheral devices. If the Blackfin is the master, then the problem is much more complicated. USB - on the Go parts might be a solution.

hi, i already worked with adv7183 but with my own developed adsp2186m board... when we configure the adv7183 internal register througn i2c communication,some register makes probs in configuration...but if the register got one time configuration then never come probs...i had so many probs in configuring registers... and also it is better u to have control on ISO pin directly.always hardware control is comfotable one. i done this same application that u specified in your mail,i.e capturing on picture and doing some operation on that captured image..but i have control with ISO(hard ware version of traq bit) pin.. with good regards ayyams --- Sthane_GOUEL_Arbos_Ingenierie <> wrote: > Hello > > I've have problem to configure ADV7183, in order to > manage PPI transfer. > > It works fine the first time : > > Configure Flash > Reset ADV > Configure DMA > Configure PPI > Configure DMA_ISR > Start DMA & PPI > > My goal is to catch a picture, send it on a screen > (via PPI bus, using > DMA) and after catch a new picture but I don't want > to reset ADV7183 > each time because I've to wait time to lock after > reset !!!. > > I tried a lot of thing such using TRAQ flag of ADV, > stop transfer in DMA > interrupt, and enable again with ADV7183_OE, but it > doesn't works.

Hello Thank's for your answer. After a check, I have 3 references for USB chip's working as host : Philips ISP1161A Cypress SL811H Cygnal C8051F320 This research is for a student project (Engineering School). So, throught this 3 chips, which one is the easiest to use, because students have only 4 months.
