Hi. I made a circuit test on which I installed the module TC65 v3. Well, once powered, it starts only pulling down the IGT pin. In Application Note 24, sec. 2.18.3.5 there is an example of autoignition of the module, in which you see a BJT resulted in saturation after applying power supply, i.e. when the bjt is in saturation, the IGT pin is low (~0.2 Volt) and this switches on the module.

Well… It seems you’re right. Thank you. The “TC65 HW Descriptions” says :

When the TC65i module is in Power-down mode or Charge-only mode, it can be started to Normal mode or Airplane mode by driving the IGT (ignition) line to ground. This must be accomplished with an open drain/collector driver to avoid current flowing into this line.

I added this because I said to someone “I think you have to connect the IGT to the power input” and he replied me that it worked. So I’m not sure whether it actually works or not. If you could test it and give me an answer, it would be great.

Hi. The last faq, about switching on automatically the module. confuses me.
In fact, I read in the “TC65 HW interface description” that to switch on the module needs to pull IGT to GND for at least 400ms, i.e. to low voltage not to power (high) voltage.
Is it correct to connect the IGT pin to GND for automatically switching on the module while it is powered and to leave this connection during the running ?
thanks

[...] the way, I updated the TC65 FAQ to add questions and answers collected from the javacint group. I created this google group a year [...]

About the SDK : You’re welcome. It’s very frustrating to have old tools when you know better one have been released.

I would prefer if people contacted you on the javacint group as we could all benefit from your knowledge around Linux development.

Hello Florent.
Thank you for the Downloads page, now I can use the latest SDK

To any TC65 Linux developers googling help:
Also, if anyone needs help in developing TC65 under linux can contact me: 3esmit [at] gmail [dot] com

I have two methods for doing the MES, one is discribed by the community in the link you posted, other is from Ondřej Janovský , who made a tool in Java using the RxTx library, that is great cross OS, simple and clean, but I’ve got problems with RxTx in the latest kernel.
Here, in the free world, we are all open source, so all the programs will be sent in sources.
