Reprogramming a Spirit1 USB Dongle for different frequencies?

Posted on October 16, 2014 at 09:32

Hello,

yes, it is possible to operate in the 921-929MHz band with the STEVAL-IDS001V5. 

Are you planning to use the GUI or to develop a custom firmware? 

• In case you use the GUI, it's enough that you set the chosen frequency in the ''Frequency base'' field. 
• Instead, if you want to develop a custom firmware, the installed software package contains also support 

  and code examples 

  for SPIRIT1 firmware development. In order to use or modify the provided example projects, it is required to have installed IAR Embedded Workbench for ARM (v6.40 or above) and a JTAG interface like ST-LINKv2 or IAR JLink. 

By the way, please note that it is not possible to get 1W of output power with the present hardware configuration: the maximum output power is not higher than 12dBm.

Regards!

Hi Gaetano

Very much appreciate your response.  From what you say we should be able to use the device.

We typically use open source tool chains rather than IAR, for example to programme STM32W108 USB dongles.  Is there any reason why we should not do the same with the

STEVAL-IDS001V5?

Very best regards, Ron

Hello Ron,

we use IAR, but you can use your favourite toolchain, clearly modifying it as needed.

Best regards,

Gaetano
