Re: BuyDisplay (EastRising) Display ER-TFTM070-5V4 connections
The correct connector to use for interface is the 40 PIN connector. I cut pins 11 and 12 off the connector and then a 10 pin header fits on the first 10 pins of the 40 pins perfectly. Make sure you

BuyDisplay (EastRising) Display ER-TFTM070-5V4 connections
I've been wrestling with the datasheet for this 7" display. I checked all the jumpers and it is configured as 4-wire serial. It seems like there is a typo in the datasheet, as they have two J2

Re: Initial Test of Main V12.6 board
Embarrassed grin... I soldered the Audio Adapter board on reversed. Good news, so far, is that it now recognizes WIRE at 0x0A on both boards. Hopefully, I didn't fry anything. John K1JO

Re: Codec & ADC's
Interesting.? The Tympan library is still converting from/to I16.? Its quad object looks similar to mine.

Re: Codec & ADC's
I think the 2-channel works up to 32-bits without that "#define I2S_BUFFER_TO_USE_BYTES(...) ".??? That define? may be old code that got left behind, I'm not sure.?? Looking at the begin() for

Re: Codec & ADC's
I tried the 2-channel Open Audio I2S objects as 32-bit but the output was distorted.? I might be missing something, but it appears to need more than just changing a define.? I found the Tympan

Re: Codec & ADC's
Hi Greg and Terrance -? I'm catching up on this.? And, not looking at the begin() end() issue, but just at the Quad I/O in F32.? I'm reading as I get time today, but here are a couple of thoughts.

Re: Codec & ADC's
As we know the documentation is a bit sparse.? You can get some of the designer's intent from looking at the examples.? I guess I need to go back and look at more of them. Beyond that and simply

Re: Codec & ADC's
I couldn't find the source, but I thought I read that the intent of the begin and end functions was to provide a quick, efficient way to start/stop the data flow.? The processing of the data,

Re: Codec & ADC's
It would seem that the interface should be consistent, where applicable, to all of the objects.? So that means any sort of complex data consuming function should have a begin() and end() function. An

Re: Codec & ADC's
Some OpenAudio library objects, AudioConvertxx for example, can't be disabled.? They continue to process as long they receive data.? It wouldn't be difficult to derive a class that could be

Re: Codec & ADC's
Hi Mark- I use a combination of switches and mixers because some things have to be both disabled and bypassed.? For example, the receiver equalizer can be active, or inactive and bypassed. So I do

Re: Undefined reference to. . . When compiling
Duane: Those are function calls that the linker cannot find. This is usually caused by forgetting to #include some specific library. Look in the SDT.h header file, near the top, to see a list of the
