STORING ADC DATA

1. You need to use NV to store your data.

2. It should be no problem to flush data by UART.

Thanks Yikai Chen,

1. Is there any example of how to do this in the API or somewhere??

Specifically with storing ADC readings.

2. I am have been reading in the forum SNV and OSAL_NV which of these is better??

3.NV copies the data to flash memory right? So whenever i ask for the data: It has to be read into a buffer before i can send with the hal write or flush? 

Thank you.

Joseph.

For 1 and 2, I would suggest you using osal_nv_xxx API like the following example.

int16 adc;

uint16 nv_adc_id=0x0401; //Ref from ZComDef.h

adc= read adc value somewhere...

osal_nv_item_init(nv_adc_id, 2, NULL);

osal_nv_write(nv_adc_id, 0, 2, &adc); //Write adc value to NV.

osal_nv_read(nv_adc_id, 0, 1, &adc); //Read adc value from NV

3. Yes, you need to use osal_nv_read to read adc data from NV to memory first. Then, you can send to UART.

Hi Yikai Chen,

Thanks for the previous post.

According to this post http://e2e.ti.com/support/low_power_rf/f/538/p/273505/959274.aspx#959274 i can only use the osal_snv for the my cc2540 module. It also seems that the OSAL_Nv.c file is missing from the cc2540 stack. So my question is will the osal_snv work for my purpose too?? If yes can i use the same example above??

Thanks,

Joseph.

Sorry, it is my mistake. For cc2540, you should use osal_snv_write and osal_snv_read.
