Other Parts Discussed in Thread: CC2538

Is there any demo videos ??

I went through the data sheet of cc2538 and it is given 512-kB, 256-kB or 128-kB In-System- Programmable Flash. So how it is configured?

It is also given that it Supports Dual ZigBee Application Profiles. How???

    I have answered your question in your previous post.

    Different flash sizes correspond to different part number, where the corresponding flash element banks are enabled. 

    The 512KB flash size is the biggest one and can potentially host two parallel stacks (including NV) based on 802.15.4 radio.

    Even though this is technically feasible, dual stack would have to share an 802.15.4 single radio through time multiplexing.

    So this may result in a sub-optimal performance of the overall system, depending on the application. 

    Thanks,

    Hi Guys, I have been trying to fond out how to post a new log but i couldn't and that might be because i'm new here.

    I need help on how to use the Burst I2C read on the CC2538.

    I'm sorry for posting this here but i have run out of option. I'm trying to read the ADXL345 registers using i2c.


    thanks

    You can download and install CC2538 Foundation Firmware. There is I2C example.

    thanks for your reply but that I2C example doesn't show how to receive multiple byte simultaneously

    Yes, the I2C example provides basic usage of driver and you should revise it to fit your application accordingly.

    i need help with using the following command.

    I2CMasterControl(I2C_MASTER_CMD_BURST_SEND_START)

    I2CMasterControl(I2C_MASTER_CMD_BURST_RECEIVE_START)

    I2CMasterControl(I2C_MASTER_CMD_BURST_SEND_CONT)

    I2CMasterControl(I2C_MASTER_CMD_BURST_RECEIVE_CONT)

    I2CMasterControl(I2C_MASTER_CMD_BURST_SEND_FINISH)

    I2CMasterControl(I2C_MASTER_CMD_BURST_RECEIVE_FINISH)

    I2CMasterControl(I2C_MASTER_CMD_BURST_SEND_ERROR_STOP)

    I2CMasterControl(I2C_MASTER_CMD_BURST_RECEIVE_ERROR_STOP)

    The example only show how to send an receive a single byte ad a time. I want to send and receive multiple byte.

    If anyone has and example on how to do that I will really appriciate it.

    I have the ADXL345 accelerometer connected on my CC2538 SOC. and I need to send burst of 2 byte to set different registers and I need to do a burst read to recieve 6 byte from the registers. I think I just don't know how to go about it.

    If you have and example showing how a burst read and write is done in the I2C line I can start from there

    Thanks
