[Question]Touch Coordinate - Auto upload
Hi,I am currently working on a new DMG19108C116_02WTR module DGUSII and I want to get touch coordinate whenever the user touches the screen along with the the buzzer sound. The 0x05 address @ CFG files says the data upload and sound by enabling .4 & .3 bits respectively.
But I don't get any data upload and no buzzer sound also even after enabling both under CFG file.
Hello, in DGUS2 mode, you can read the 0x16 command through the serial port to get the status and coordinates of the press, and then send a command to make the buzzer chirp when a press is monitored. Ok. Thanks 本帖最后由 babusujay 于 2022-5-6 12:57 编辑
Here I go again, I have two more queries.
1 )Is it possible to display text without VP like what we do in TA ? It is useful for us in debugging during run time and I can't make a fixed text area with VP assigned.
( 2 )Whenever I use 0x82 write command I get a feedback response from the DGUS like " 5a a5 03 82 4f 4b ". Can I avoid this ? Somewhere in the forum I read that it is possible to so by loading "T5L_OS_DGUS2_V10_82 command no response . BIN". Is this BIN file compatible for my DMG19108C116_02WTR ? Will there be any consequences on receiving touch coordinates ?

If DGUSII is developed, it can only send commands to display text through the VP address. Downloading the unanswered kernel can close the 4F4B command to confirm the response. Thanks a lot. I am trying to make use of the Audio output from DMG19108C116_02WTR. I have created a 16.WAE file which contains around 20 WAV files. Configured the CFG file with necessary changes like hex value 0x78 @ address 0x05 andhex value 0x10 @ location 0x07 . Connected 4ohm 5W speaker , but the audio output is very low in a way that even at three feet distance we could not here the sound.
Speaker has been checked with different audio source and found that the speaker is perfect. Measuredthe wire resistance between speaker and audio output and the resistance is almost 0.1 ohm.
So no speaker issue and no cable issue but still the output is not at all audible. Am I missing any other setting ?
We used LM386 with 1W speaker for the same wav files in our older system and the sound is audible even at 15 feet difference.
I tried with two LCDs , but the end result same.Do I need to introduce another amplifier like LM386 between audio output from LCD and speaker?
