Palmsens EmStat Pico Dev Kit MethodScript Questions

Category: Software
Product Number: Palmsense Dev Kit
Software Version: PSTrace v5.10 Beta

Hi,
we are using several Palmsens EmStat Pico Dev Board using PSTrace v5.10 Beta.

We are using MethodScript to write data to SD card and and use BLE to also transfer data, and have the following queries:

  • Upon removal of the SD card, we cannot view the contents of this SD card using an SD card reader - is the card a proprietary format or regular FAT32?
  • We have been trying to append data to a previosly created file on the SD card. However PSTrace only seems to be able to access the last data section appended to the file, not the entire file. How do we access the entire data file?

  • Hi VCrabtree,

    • Upon removal of the SD card, we cannot view the contents of this SD card using an SD card reader - is the card a proprietary format or regular FAT32?

    It is a proprietary format, this was needed to better handle possible data corruption on loss of power, and to reduce write latency.

    We have been trying to append data to a previosly created file on the SD card. However PSTrace only seems to be able to access the last data section appended to the file, not the entire file. How do we access the entire data file?

    PSTrace does not fully support measurements stored in MethodSCRIPT, only those that are stored using a normal PSTrace measurement. This support is a planned feature, but I have no ETA on this.

    That said, if an existing file is opened in append mode, all data should be appended. Take care that appending does cost a fair amount extra memory. This data can be parsed by one of our SDK's, found here
