PMIC wanted for MX6SLL, with charger

Wed, 2019-02-13 15:27--RobertS

Hi,

We are designing an i.MX6SLL device with a display an Li-Ion battery. 5k initial production, with the option of using on further designs.

We would like to see if Dialog can supply us with a suitable PMIC, particularly one that integrates charging from USB into the PMIC.

The DA9053 has caught my attention, and I am wondering if it is compatible with the i.MX6SLL with LPDDR2/3.

Could you contact me about this, please?
我们一直与Avnet交谈,所以您可能会通过它们获得同样的询问。

Best regards,
Rob

Emulation

Wed, 2019-02-13 13:42--jwh

I just received the advanced development kit and use the SLG44620 device to do some tests. It is probably a dumm question but I'll ask it anyway. I'm trying to run an emulation using the LF oscillator and an input pin directly coupled to an output pin. Both outputs seem to work as a see the OSC signal on pin 17 and the output signal on pin 15. I'm using the expansion connector with both signals connected to a scope. What I don't understand is that I don't see the generator signal on pin 16 of the chip.

DA7217 System Controller 1

Wed, 2019-02-13 00:47--jimmy.wang@adap...

Hi,

I am trying to program the DA7217 with two ananlog MICs input and I2S output. The sampling rate is 16KHz. MCLK is 24 MHz. My IO voltage is 3.3V. I am running the codec in master mode. After programming the necessary registers, the codec seems running: it generates the correct 16KHz WCLK and 512 KHz BCLK. However, there is no data on DATAOUT line. I checked the mic input on my scope. The input signal varies with my voice. So somehow the data is not routed to the I2S bus.

我读的大部分食物后寄存器值ramming the codec. The file is attached.

I2C control

Subject: SLG46826 real-time control via the I2C bus...

Your inquiry/feedback:
Want to know if the I2C interface to the SLG46826 is useful as a way to command the I/O pins after the device is programmed.
If so, how does one set up the part to do it?
Can I read a command sent from a host devices via the I2C bus, and interpret the command to toggle a pin?

Thanks

Custom DSPS application not receiving all bytes

Mon, 2019-02-11 22:13--ao

Hi Dialog,

I am currently developing firmware using the DSPS application with a DA14580 chip on a custom board. In this project, I am using a GPIO pin to turn on and off an external microcontroller in order to conserve power when the microcontroller is not in use. When I need to use the microcontroller, I send a short command to the DA14580 using a mobile phone, the DA14850 then wakes up the external microcontroller with a GPIO pin, sets up the UART, sends the short command, then waits to receive data to send to the phone.

DA7217 Register Settings

Mon, 2019-02-11 18:00--jimmy.wang@adap...

Hi,

我的da7217数据规格版本为3.1。我对注册设置有一些问题:

1. Page 61: for the PLL, Table 47 indicates that it needs to set register 0x27 bit 3:2. However, pll_indiv bit in register 0x91. So I suspect table 47 is wrong

2. Page 115: I suspect Table 163 bit 3 is wrong. According to MIXIN_2_CTRL, this MIXIN_1_CTRL bit 3 should be mixer enable not amplifier enable. the amplifier enable bit is bit 7.

DA7212 - Mic_1 echoes the same audio played over HP_L/HP_R

Hi,
In our application, we are using DA7212 as audio codec for Bluetooth headset. 1.2k Ohm analog mic is connected to Mic1_P/Mic1_N in differential mode. Following are the mic configurations,
MIc_bias = 0x08;
mic_1_ctrl = 0x80;
mixin_L_select = 0x02;
mixin_L_ctrl = 0x88;

mixout_L_select = 0x08;
mixout_R_select = 0x08;
