We now have available our new SO16B micro-coprocessor kit. The micro- coprocessor provides 16 pins for PWM (2 styles), pulsed output, blinking, flashing, beeping, and more. Over a dozen output functions, fully simultaneous on all 16 pins. Fast, simple, 1-pin serial interface. Complete kit with board, LEDs, regulator, $25. Full BX24 code example at our web site.

Chuck, Sounds interesting, but when I look at the website, the S016B is $95 and the M016B is $25. I also didn't find the code yet. I am new to electronics. If you really do mean the M016B, then I can have 45ma of power at each point. How would I drive a big motor with PWM? Don't I need more power than 45ma? Thanks. - Tom -----Original Message----- From: Charles Davis [mailto:] Sent: Monday, June 05, 2000 3:50 PM To: Subject: [BasicX] New Product Announcement We now have available our new SO16B micro-coprocessor kit.

Chuck, Micro's (and other semiconductors) typically only provide current in the mA range. To drive larger loads you can use the mA output to drive power transistors, mechanical relays, solid state relays, SCRs, etc. Martin http://www.selmaware.com --- In , Tom Lageson <tlageson@s...> wrote: > Chuck, > Sounds interesting, but when I look at the website, the S016B is $95 and the > M016B is $25.

The total current allowed for the chip is around 100 ma, the processor takes about 40 ma of that for its own operation and what's left (about 60 ma) has to be split among the 16 outputs. 45 ma is the limit for a single point, but that would assume the other points are drawing much less power. 45 ma x 16 points would be almost .75 amps, way beyond the capability of any microprocessor chip. Driving a motor from any microcontroller such as this (this includes a BX or Stamp) always requires external power driver circuitry, typcially an H-bridge circuit if you need bi-directional control, or a power transistor of some type for uni-directional control. The MO16B can provide the signals, but it can't provide the power. Our other cards have a variety of power drivers on board - the MO16B is designed for people who will be providing their own power drivers or other interfacing circuitry. I apologize for the code - among all the changes just made to the web site, posting the code was omitted. The stamp version is there, the BX version will be added later this evening.

the code is at http://www.oaktreesystems.com/Documents/ots_sample.bas with one of the pins of this 16 pin micro-coprocessor you can drive a "h-bridge chip" that will run a 3 amp motor. 45 mA is more than enough to run this chip. http://www.acroname.com/robotics/parts/R27-18200.html Acroname Parts: National Semiconductor LMD18200 3A 55V H-Bridge this chip runs a max motor voltage of 55v. I run mine at 12. this is just an easy way to make the PWM. --- Tom Lageson <> wrote: > Chuck, > Sounds interesting, but when I look at the website, the S016B is $95 > and the > M016B is $25.
