BS2 code for INA 219 DC Current Sensor - Product 29130

John Kauffman

There is code on Prop OBEX, but what about BS2?

Franklin

Does not look like it. Can your stamp do I2C?

John Kauffman

Thanks, Franklin.

Looks possible for any BS2 to do I2C: http://forums.parallax.com/showthread.php/82908-I2C-On-A-BASIC-Stamp.

It would be great to have a P'Lax solution. I know Plax is full press on Prop, but it will be great when the new products hit the shop with BS2 code or a clear note on product page that the product is not suitable for BS2. I've got a couple dozen BS2s and a hundred students that learned on & have BS2. I won't have transition to Prop done for a few years.

Not a big deal, I don't need it this week and someone with BS2 / I2C expertise will throw the code together in an hour.

Nuts and Volts #85 has I2C code for a BS2 that you can modify to meet your needs.

As John mentions in that thread you referenced, StampWorks Experiment #20 also has I2C code. He also mentions Nuts and Volts #115 and #81.

If you read the prop code you can see what is being done, that might help translate.

True enough, but there's a lot of code overhead, kind of headachey.

The 2P, 2PE, 2PX have the I2CIN and I2COUT commands, streamlining things tremendously.

Thanks. I'll use one of the higher capacity BS
