Re: Sending iR codes from an iRobot Create

I found a copy of the iRobot create online..and it seems LD1 can take up to 0.5Amps (please verify that first to avoid damage, as SendIR can draw up to 350mA at full power setting using both jumpers). If this is the case then the solution may be much simpler..(not as designed, but should work...TBC)...

Re: Sending iR codes from an iRobot Create

OK. All seems as expected. The circuit above should(?) work, if placed between the iRobot & SendIR. Please upload a photo clearly showing the wiring with the connector, SendIR & the NPN circuit above. You say it works without the 100R resistor (but try with it out and in... i.e. connected between 5V...

Re: Sending iR codes from an iRobot Create

First of all, I am not familiar with iRobot. I am assuming the circuit you posted is from the iRobot. Maybe post some photos of your setup , including the iRobot & if there is a standalone IR emitter/remote? For now I will assume the circuit you posted is from the iRobot itself. Just to be clear, th...

Re: Sending iR codes from an iRobot Create

Based on what you have posted...you will need to invert the signal coming from the LD1 pin/connector(?)

something like this should do:

T1 is an NPN transistor like 2N2222 or any generic NPN transistor should do.

Re: Infrared with msp430

Sorry...I am not familiar enough with msp430 to comment or debug your code for you. However, if you do a google search for msp430 and NEC, you should find some examples as I did. Also, when posting code online, make sure to use code tags and indent the code to make it readable. What you have posted ...

Re: Infrared with msp430

but i don't use Energia unfortunately. OK, but you could study it to check how it is done for MSP430! I would not advise using a UART for IR.(Although we have some posts on our blog showing how to generate IR using a UART). In generat I would suggest using something like the NEC protocol as a good/...

Re: Infrared with msp430

Have you tried using the IRremote library with Energia?
