I am connecting CP2615-EK board to Meizu Pro 7 smartphone (Android 7.0) via USB OTG adapter as described in User Guide. But there is no sound on headphone jack when I try to play music from the smartphone. Though I can control playback, volume etc. via buttons on the board. How to enable headphone output?
I have the CP2102N connected by shorting Vregin with VBu, the datasheet recommends using the voltage divider for optimum operation. Now with the voltage divider, the voltage at Vregin is 3.1v so would it be ok to short it to VDD as it has the same voltage ?
with current connections all works well.
Windows 7 (64-bit) can't find drivers for CP2615 from CP2615 evaluation board. What to do in this case?
I am using CP2120 to interface with an i2c temperature sensor, i was able to write to the temp sensor successfully,
when i try to read the same register i wrote, the I2CSTAT register always shows that i2c transaction in progress, when i connected the i2c end to a logical analyzer it shows that the temp sensor is sending back the requested data with correct values and CP2120 receiving it properly(it acknowledges and raise stop condition after receiving intended number of bytes). some how it does not trigger the I2CSTAT reg to update to 0xF0, i read one of the thread in this forum and tried enabling I2CTO and I2CTO2 ..still no luck.!!
then, i neglected the I2CSTAT and started polling RXBUFF len register , luckily it was updating it to the received data len.. then i tried to read receive buffer which always reads 0s not the receving data over i2c, Not sure what stops these registers and buffers(I2CSTAT and RXBUFF) to update during the reception of i2c data.
i appreciate your thoughts!!
I have a CP2615 which is configured to keep both MCLK and LRCLK active at all times - but this does not happen under all circumstances.
There appears to be a state where the audio driver shuts down the part and the clocks stop. I can trigger this every time using Windows Media Player; when the audio track stops the clocks continue but if the program is closed then they stop.
The reason for wanting them active is that the product I'm designing also has an analogue audio input and I need the clock source to be able to handle this.
Is there a way to stop this behaviour? The datasheet is not very clear on this feature.
Hello folks, I have a CP2102 device that was supplied to me configured as 'igenico 3070'. I can communicate with it as a Com Port (Windows 7) after installing the igenico drivers.
I want to reset the device to default CP2102 using Xpress Configurator. However, this device doesn't show up under 'devices' in Simplicity Studio. Is there anything I can do here?
Thanks in advance
Hi... I have the above USB to UART bridge which is used to interface a CHI660c potentiostat.
For the most part it works well with no problem. However when some applications are used on the potentiostat , the software will hang, seemingly at random and I will get an error code category (101), event id 1002. My OS is Windows XP service pack 3.
What can I do to stop this software hanging ? I think the problem may lie in the various other applications also using USB.
I'm designing a board the with CP2130 that will connect to SPI salve that need to be 3.3V and 1.8V configurable.
When looking in the CP2130 datasheet it is clearly state that the support for I/O interface voltages down to 1.8 V, so it can be 3.3V or 1.8V.
What I'm not sure off is that the 3 SPI pins are in fact powered by the same VIO, as the other 11 GPIOs of the IC
Can some one please confirm that?
Is there any way to adjust the timeout or number of character periods to wait after buffering data on the RX side of the UART before the chip sends the USB report?
My microcontroller will send variable sized packets ranging between 4 and 40 bytes.
At higher baud rates, more often than not, the entire packet will come as one HID report.
At lower baud rates, (9600, the maximum when playing and recording audio), the packet is divided into 1 byte HID reports, and I must re-assemble them on the host, not to mention the overhead.
It would be useful to know what the timeout period is, if indeed there is one, whether or not it's adjustable, or if the chip periodically checks to see if the RX buffer is non-empty and sends what's in there.
