Re: Simple example of I2c code " My World" request

Okay, the data sheet indicates that P0.10 & P0.11 are not open drain pins pg 8 of the DataSheet, - may need to select another pair. The GPIO section does mention that most pins can be configured for 'open-drain'; so I assume those can't be 'opened' - maybe need a different pair. ' since you are usin...

Re: Simple example of I2c code " My World" request

Hi, Have you been able to run a scan detection for the I2C address routine? It normally scans all legal addresses, and then spits out some kind of address list/display? ' I am currently looking for one. Gary Olzeke51 here is some code for scanning devices , I had it working on a different board than...

Linux TclTerm baud rate

Hello Basicchip - (the 'windoz' guy') Gary here (a real Linux user). . Using TclTerm.tcl on Linux - it is simple to use, I enjoy it. The Windows version will allow me to change the baud rate, BUT not the Linux version. Some of my boards use a lower speed UART. . Could the pull down for Baud Rate be ...

Re: Man Cave Accessory

more info: This is for the NEC codes that the IRRemote transmits. The Arduino Library has coding/timing for the other brands. The use of Interrupt timing was garnered/modified from the Arduino code . I used the falling edge of the signal from the detector to create an Interrupt. The ISR (Interrupt S...

Re: Man Cave Accessory

this is the basic setup [schematic]
Pin assignments are upto you or in the program to be posted later.
CAUTION: A0 needs to be input from a 3.3v device as noted in the drawing.
'
be sure to isolate all of the pins[used] on the dimmer so the original dimmer circuitry
does not interfere
