I can see why you are looking for other options. The chip is still available (somewhat), but at $40 I would examine other avenues as well. I will look for a few distributors. If a good price appears, I will let you know.
Are you on a time constraint for this project? Did the person who designed it offer the code? Did same person offer preprogrammed chips?
Not too many hobbyists that I know of use Philips microcontrollers. The most popular are Atmel, Microchip, Texas Instruments, and multiple sources of 8051...
Maxim: digital pots, I/O expanders, real time clocks, nonvolatile memories, temperature sensors, LED drivers, switching regulators, voltage references, rs-2322 interface...
Allegro: hall sensors, current sensors
You are asking STATE_MACHINE, but I will tell you my experience. Samples I have requested from Texas Instruments, Maxim, Analog Devices, MIcrochip and Allegro have been shipped to me without complication. Some of the items I requested from TI were rather expensive.
I have requested samples...
Hello Roomi. There were a few mentioned by you and STATE_MACHINE that I had not known. It will take some time considering the season and road damage in my area. I will let you know when I find out.
First off, the priest thing is humor. "I'm a ttibetan ppreist" is replacing the default line "I'm a llama". In my country, most people with english as a primary language and nearly everybody with it as their only language pronounce "llama" as "lama". The correct form is "yama", so when they...
Wow, there're a few new ones I haven't sampled yet. As always I re-enter my name in the company field (I keep good company). My title describes what I do in my free time. One wanted more than one line of street address, so I specified my brewing shed. I will find out soon enough.
I wouldn't recommend it. Perfect matching can't be guaranteed, and failure to use resistors to distribute the current could result in one or more triacs turning off and the remaining would overload and perish.
Ah, I see. I have no experience with the BS series. I did just look at some of the literature though.
I have not determined whether or not you can access TMR1, but even if you can the BS1 uses a ceramic resonator so the frequency will wander. Alas, the external hardware is necessary.
Just...
Well jcbarber, you have an almost limitless variety to choose from. You can expect better accuracy from crystals than ceramic resonators, the flip side being that resonators are usually cheaper- but for one-off projects that won't matter much.
You said you wanted to use 100Hz for your master...
I won't bother quoting the exact words they used, but the way I interpreted it was: "If you're smart and/or educated, we don't want your business!"
Did they mean to insult me/us? Maybe I just want an excuse to get irate.
I'm working on a house that needs nearly everything brought up to code. While the walls were open, I put in enough media drops to run an arcade (30 ethernet points, assuming I don't start using the 'phone lines too). I gave it some thought, and decided not to include any heavy wire- so no...
I used ot tear just about anything apart. Now I try to limit myself to things that I know have something I want in them- like nokia 5160 (and similar) cellular 'phones, they have a graphic LCD with serial input.
I have one that's close to that- I think about 150*200mm. It is buried away at the moment. The other problem is I'm on another continent, to shipping would be stiff.
If you're that desperate for it, I'll dig it out and see if I can find a rating on something similar and look into shipping...
I've got another wild idea. I"m thinking about putting a little ferrofluid into a stepper motor to see if there will be any improvement. I'm wondering if it will do more harm than good. I know there will be dome inertial damping, but I don't plan on running it anywhere near full speed. Will...
