Other Parts Discussed in Thread: CC3220MOD
Tool/software: TI-RTOS
I am new to Simplelink. I am looking at a project to play audio files on an SD card using the CC3220MOD. I can not find any reference to the use of the I2S peripheral in the CC3220 datasheet. I've worked with I2S before on other processors and I know I need clock, data, and frame select. I'm a bit confused with the two data lines McAXR0 and McAXR1 as my experience has only been a DAC with one data line. So, I'm looking for help mapping out pins for my application.
I also want to show graphic files on a 320X240 TFT panel (SPI connection) from the same SD card. Any comments on this would be appreciated. Just static images and no video. Maybe slow and crude animations. Throughput will set the speed limit here and I'm not sure what to expect.
Here is my schedule of IO that I plan for this project:
Display (SPI): GPIO 14, 15, 16, 17
SD/MMC: GPIO 9, 10, 11
I2S(DAC): GPIO 0, 8, 30
I2C: JTAG_TDI, JTAG_TDO
UART0 (debug): GPIO 12, 13
UART1 (RFID): GPIO 3, 4
NeoPixel (PWM): JTAG_TCK
Can someone tell me if my selections will all function together. I'm a bit concerned with the I2C port sharing with JTAG. Anything I need to be aware of there?
Has anybody driven NeoPixels with SimpleLink before? Needs 1 pin with critical timing. Could possibly be implemented on PWM output pin.
Is there a Development Board with an SD card available?
Thanks in advance for any help.
Mike.
