The "Getting Started" datasheet iilustrates that pin #1 on the 28X1 should be tied to +5V with a "4k7" ohm resistor. Does that mean 4.7K or 47K? Thanks.

I'm using a 28X1 chip and readadc10 to input a signal from my infrared range sensor (Sharp GP2D120). The signal is proportional to distance. The unused readadc inputs are tied to ground with 10K resistors. Everything works as expected. What is not expected is how noisy and unstable the...

Currently using a 14m chip and running out of variables fast. Reusing helps, but more unique variables is ideal. I'm moving up to the 40X2 chip, but I'll eventually run into the same problem. Does external EEPROM offer more? Will picaxe ever expand to the new PIC 32-bit chip?

Using a simple 08M chip, I'm measuring light intensity with a phototransistor and reading the analog voltage with "readadc". I'm feeding those voltages to Matlab with the "sertxd" command. Question... is it possible to capture time or sample rate and output that with "sertxd"? Using the...

Hello, I'm baffled with the speed of the 08M sertxd command. The baudrate for this chip and function is 4800 bits per second, or 600 bytes per second. I wrote a short & simple routine (see below) to output a variable called "light". Code execution takes time, so I expected the code to...
