[Owfs-developers] problem writing PIO on DS2413
Hello, I have a DS2413 attached to a serial master DS9097U-E25 with owfs-2.5p1 . On power-on both PIO.A and PIO.B read 1. Any attempt to write to PIO.A, PIO.B, PIO.ALL, or PIO.BYTE is just ignored (LEDs are attached for monitoring). If the value of e.g. PIO.A is read back immediately after being written, the data is garbled: echo 0 /mnt/1wire/3A.7C31/PIO.A; cat /mnt/1wire/3A.7C31/PIO.A 2Ùæ§HÙæ§cat: /mnt/1wire/3A.7C31/PIO.A: Numerical result out of range and after waiting for a couple of seconds PIO.A reads 1 again. Has anyone a functioning DS2413 switch? Is this likely to be a software or rather a hardware error? Other sensors (temperature) on the same bus are operating normally.

Hello, What happens to the uncached values? They do not show the garbled output but just ignore the write attempt.

Re: [Owfs-developers] Serial Port Requirements
Hi, I see your problem, but on the other side you have all motherboards with PCI slots (which have SMBus contacts) and any recent RAM slots which have on-board SMBus controllers but no generic I2C host chips. And most of these are already supported by the kernel. From what I could see in the w1 kernel code, all commands to the I2C-1-Wire bridges in fact are also SMBus compliant and thus the use of the kernel smbus layer seems more natural. The linux kernel i2c system automatically translates SMBus packets if they are sent to a true I2C-master device (e.g. parport bit-banging). If you have to write a layer on top of your proprietary I2C library anyway, couldn't you copy over the SMBus - I2C functionality from the kernel source?

I'm still into bugging them to make a driver using the generic i2c interface, but if this fails, I'd have to port the owfs i2c Interface to that libary. It would make things easier if you could stick to the raw i2c calls of the /dev/i2c interface. --- Using Tomcat but need to do more? Need to support web services, security?

Re: [Owfs-developers] Serial Port Requirements
Hi, Besides more restrictive electrical specifications and timeouts to prevent the bus to be locked, SMBus is a subset of I2C, i.e. for the protocol every I2C master device can send all commands a SMBus slave is able to understand while this is not true the other way around. Because of this it would be better to stick to SMBus commands. If the PXA board is truely I2C it should be no problem for it to issue all the SMBus commands. That it is not SMBus compliant can only mean that it has other electrical characteristics or does not support the timeouts required by SMBus.

Near as I can tell, there are only a few primatives: DeviceReset 1W reset 1W channel select 1W read/write byte 1W triplet 1W powerbyte Some things, like selecting i2c address, and distinguishing between -100 and -800 aren't so clear.

Re: [Owfs-developers] Serial Port Requirements
Hi, as far as I remember the header file which is supposed to be used with userland programs is distributed as part of the the lm-sensors source package as it is needed also in the sensors-detect program.

Re: [Owfs-developers] w1 changes
What should the command line interface look like? owfs /dev/i2c-?/address Seems good, the address would be an integer between 0-127 for the standard 7-Bit I2C-addresses? The 10-Bit addresses are included in the I2C standard but the kernel support is only experimental since no known I2C devices with 10-Bit addresses are known yet.

Re: [Owfs-developers] w1 changes
What should the command line interface look like? owfs /dev/i2c-?/address Just a suggestion concerning the internal structure of such an adapter: If you look at Documentation/i2c/smbus-protocol it seems to be better to implement it only using the SMBus subset of the I2C protocol, if at all possible. Otherwise owfs would have to check whether the /dev/i2c-? device really supports the full I2C protocol (see Documentation/i2c/functionality ). The advantage I see with implementing the adapter based on the SMBus protocol is, that most motherboards contain SMBus controllers that are supported by the I2C subsystem. You can get access to theses buses e.g. off of SDRAM modules (see http://www.madhacker.org/locate_smbus.htm ) and the DS2482 could be easily (internally) attached to any PC.

[Owfs-developers] w1 changes - DS2804-x00
Hello, first of all I apologize for breaking the thread but I just subscribed because of the recent discussion about kernel w1 adapter support. As I understand you were looking for beta testers and their specific setup (thread started by Stuart Poulton on Feb 27, 2006). We are planning to attach DS2804-x00 devices to an external I2C-bus connected to the parallel port via a PCF 8584 on EPP port adapter (for schematic see http://www.voxel.at/prj/i2c/ ). We should receive our DS2804-x00 samples from Maxim soon. We intend to use DS2413 switches attached to multiple DS2804-x00 on the I2c-bus to remotely reset/power-cycle nodes in our compute cluster. We might also attach temperature sensors to remotely monitor the case temperature independent of on-board sensors in the nodes. Kind regards, Ch.
