henrik how does this look ?
can the pid routine take byte sized increments
I'm glad that I could help.
Also keep in mind that when you enter bootloader your registers are not in reset state. So I always disable interrupt and timers in bootloader.
I did the whole process EXACTLY as you described.
The things I've missed was to disable the interrupt before go to the bootloader.
Probably, the reason why I did not disabled it, is...
Weird, I was sure morse was up to 3 characters, turns out it's up to 5 characters.
I've tried all sorts of ways to try to store morse in as little space. Turns out the start bit technique is...
I have used two pics to access DS1307 some years ago, I put 470ohm resistors in line on each of the pics and used a similar connection between the 2 pics as a busy line. ( probably not the correct...
Is it possible to have 2 master I2C on one I2c display?
Like this Master1 Line 1 on the display
Master2 Line 2.
I found this on the net
As the I2C bus is a...
Yes, this exceeds the max voltage spec on the pins. Bad idea, esp the negative voltage.
RS232 levels could be as much as +/-25V, although you normally won't see them anywhere near this high out of...
No risk of overvoltage on PIC?
Sorry, won't work. You need to invert everything, including the idle state, start and stop bits, etc.
If you have device, just measure resistance from central pad to Vss. If is it short, then is safe to put ground. If isn't, then leave it unconnected.
