unfortunately I don't get anything on the oled
thanks, I went back and used the original ssd1306_I2C.inc. Now no warning when I compile. With no changes to the demo I still can't get anything to show on the oled. To make sure the oled hardware is...
thanks Richard,
I had no idea. I changed the address back to 0x78 just now and I still don't get anything on the screen. I get this ASM Warning in the results window after compiling. Not sure if...
Hello,
I need help getting this to work. My oled display does not respond at all and appears off. I'm running the sd1306_demo_16.pbp program. Everything compiles fine. I'm using a 16F1619. Here is...
jerson,
why soft and not HPWM? Honestly I'm not fully getting this...

thanks Steve,
So this would require a pause of 1 second if the reading is zero? I can't afford that kind of delay. Is there another way?

Made a mistake. I'm using a 18F4620 for this. 20mhz resonator. I'm communicating to a 16F88 but I need to have the piezo on the 18F4620. And the more I think about it I would like to have 1 beep per...
Hello,

4MHz int osc
I need to send a pulse out to a buzzer that will vary in on time. I need the program to continue running/taking readings while the pulse is generated. I have a...
Thanks both of you. After looking closer at the ADCON registers, which I had done a few dozen times, I noticed I only had seven not eight bits. Steve, thank you for your last post. When I pasted it...
Unfortunately your suggestion did not work. Here are some captured results. Starts with reading on ground, then roughly 2.5V then VDD (5V);
ADVAL_1 = 0
ADVAL_1 = 0
ADVAL_1 = 0
ADVAL_1 = 0...
Hmm, the method I’m using to read the A/D is used on the melabs examples page. I have also used this method with a 16F688 without problems. I do get a varying number when I adjust a pot on the pin...
I can not get the 10-bit A/D working correctly. The program below reads AN0 and turns an LED on if the voltage drops below half of VDD. At least that is what I want it to do. I am expecting to see a...
I need to create a checksum to send with my data over my wireless link. I have three to five string variables to send. I will not know the length of the strings as they will always be changing. Can I...
I am sending GPS data over an audio link using a modem ic. On the TX side I have broken down the GPS data and I’m sending just the speed, heading and altitude. If it matters, I’m dropping the decimal...
