3.2 Software, Development Tools, and Example Code
To enable quick development of end applications on the C67x DSP and ARM® Cortex® R4F core in the
AWR1843AOP, TI provides a software development kit (SDK) that includes demo codes, software drivers,
emulation packages for debug, and more. These can be found at
3.3 LDO Bypass Requirement
The AWR1843AOPEVM utilizes a 1.0-V supply on the RF1 and RF2 power rails. To support the third
transmitter, the VOUT_PA output is connected to the RF2 power rail. For best performance and to prevent
damage to the device, select the 'RF LDO Bypass Enable' and 'PA LDO I/P Disable' options in the Static
Configuration when using mmWave Studio. Additionally, the LDO bypass can be configured using the
AWR_RF_LDO_BYPASS_SB API. To enable the RF LDO Bypass and PA LDO I/P Disable through the API,
issue an ar1.RfLdoBypassConfig(0x3) command.
