These chips use SANYO CCB bus format. What I need to do is to access CCB interface of those controllers (drivers) and drive them over a RS232 serial port or if there is any custom made chip/controller for this purpose, it could be an option as well. These chips have CE (chip enable), CL (syncronization clock), DI (transfer data/data input), DO (data output) pins which provide external access to the user. CL is operating at 40kHz. I will appreciate your kind help. Thanks.

I have a lot of products out in consumer-land with Tigers ( Tiny-Tiger ) in them. Recently we have had reports from a customer who has problems uploading and downloading data from the module with his PC, a new laptop with internal serial port. Checked his laptop personally, and all seems ok, in that there are no other programs running to cause conflicts with the serial port, and file and text transfers between his laptop and a desktop machine running standard terminal programs works fine. However I keep getting frame errors when attempting to upload or download data to the Tiger. The module also works fine on many other PCs, all using the same software. We use the standard ser0 and ser1 hardware ports, and their device drivers, for all serial comms, ser0 at 4800 baud for connection to a PC ( and other things ) However, I finally checked the actual bit timing of the serial data from the Tiger, and found that at 4800 baud, the Tiger runs about 1.5 % fast. IE the bit time, which should be 208.333 microsec was nearer 204-206 microsec. I checked the processor clock on this individual unit, by timing a 1 second count we have available, and it was correct within 0.1%, so its not just an error within this unit. In reading of the manual, I noticed a long time ago that the Tiger seems to use a lot of funny baud rates, and not some of the more standard ones. The 'standard' baud rate system uses a 1.8432 MHz crystal, and divides by 16 to get the top baud rate of 115200 baud. All lower rates are integer divisions of that, eg 4800 baud is divide by 24. The tiger, however cant use that ( 115200 ) baud rate. The max rate they quote is 153600 baud, which is 1/16 of 2.4576 MHz. My guess is that they use an internal processor clock of 5 or 10 MHz ( based on the fact that all other timing in the tiger is an exact 1.000 msec frame ), dividing by 2 or 4 to get 2.5000 MHz for the feed to the UART. This gives an error of 1.7 % fast, propagated through all the standard baud rates, which matches close to what I measured. They dont say what the baud rate divisors are, but 4800 would be divide by 32. The actual bit time at 2.5 MHz input would be 204.8 usec - compare with what I measured above. My guess is that the particular laptop is also just far enough 'out' in speed that the combination causes errors. Has anyone else noticed problems like this ?

Tried all the baud rates from 1200 to 38400, and got the same garbage at all of them. When you see how the error is generated, you realise that that is expected. Already suggested the customer use a USB to serial converter. He is happy to do that, if it solves his problem. But the fact remains that the baud rate generated by the Tiger is wrong, and by enough to upset at least one machine. How many more are just on the edge of working ? When I have some more time, I will set up a PC and Tiger at a low baud rate, and manually run through all the divisors on the PC UART, to see what range I can get to match the Tiger, just to give some more clues. Pity we havent got access to the actual UART divisors in the Tiger, just those silly magic numbers in the device drivers to set baud rates.

The host end has to do an AWFUL lot of processing to be a host, so while you might have a very simple usb to serial at the remote end, the host is usually a PC running a large program. (I think it is called Windows, or something?) Anyone want to write "Twindows" (Windows for Tigers)???

If it is a problem, it must not be too bad. I think the Tiger has a 20mhz clock osc, so that is never going to divide down exactly to a bauld rate like 3.6864 etc rocks Cheers Ed ---- JED Microprocessors Pty Ltd, Phone +61 3 9762 3588, Fax +61 3 9762 5499 173 Boronia Rd, (PO Box 30), Boronia, Victoria, 3155, Australia http://www.jedmicro.com.au Mailto:eschoel@jedmicro.com.au JED makes PC/104, STD, Tiny Tiger and AVR based computers, displays RS485 comms, and analog/digital I/O for scientists and engineers who build things. ----- Original Message ----- From: "Adrian Jansen" To: Sent: Thursday, October 30, 2003 9:22 AM Subject: Re: Serial comms baid rate errors > Thanks for those suggestions. > > Tried all the baud rates from 1200 to 38400, and got the same garbage at all > of them.

The laptop in question is some 'noname' brand. It is quite possible they emulate the UART in software, just to save a buck, and cut some corners. Although the customer claims he uses it a lot on many other serial jobs, and never has a problem. It certainly worked fine when I sent it a 200 kb ascii file from a PC at 115200 baud. I would have thought that was a pretty severe test. I was more worried about having a heap of complaints from other customers down the track, but your experience seems to indicate that is unlikely.

Most UARTs in microcontrollers (with "even" clock rates) have those slightly off timing in baud rate. If it where a problem in general many application would not work. But i have heared about some rare caeses esp. with notebooks where problems occur. One reason could be some non standard voltage used by some "RS232" drivers on notebooks (its more 0 and 5V, not +-12V). Maybe another RS232-chip on the Tiger side can cure this.

We are well aware of that problem. I have normally accepted baud rates off by 0.5% as being ok, but 1.7% seemed a bit much. However the bulk of experience suggests there is no problem. I just hope too many other laptop and other manufacturers dont try and cut corners on this.
