Other Parts Discussed in Thread: USB2ANY,
Hi experts, I want to make a 4-20mA two-wire pressure transmitter with a PGA900, with CCS and USB2ANY can I program it? or is the PGA900EVM board necessary?

Hello Juan,
If your hex file is already complete, you can program the PGA900 through any of the available digital interface modes. The EVM and USB2ANY are not necessary as long as you have a master to supply the digital communication, and a way to pull the VP_OTP pin up to the programming voltage.
If you need to debug through CCS, you will need an XDS200 USB JTAG emulator as that is currently the only supported debugger for the PGA900.
Regards,
Thanks for your response. Does the usb2any generate the VP OTP voltage? I want the cheapest option to be able to program a PGA900
Thank you very much, so connecting the USB2ANY to the new PGA900 can I record the .hex generated in CCS?.
If you are not using the PGA900GUI in conjunction with the USB2ANY, you can still use the USB2ANY, but you will have to the refer to the USB2ANY DLL documentation to make sure that you are sending the proper commands to the USB2ANY hardware.
The simplest way to program the PGA900 would be to use the PGA900EVM (+USB2ANY) with the PGA900 GUI.
Regards,
If you pull the digital interface lines from the USB2ANY you can use it with the GUI without the full EVM.

Could you send me the scheme of how to connect USB2ANY to PGA900? I want to implement the circuit of that link, www.ti.com/.../tidrja4.pdf, but with the change of using not an RTD sensor but a pressure sensor, and being able to use PGA900 GUI or Program a .hex created with CCS.
Hello Juan,
The PGA900EVM user's guide includes a full schematic of the EVM and the USB2ANY's connections to the PGA900.

Without PGA900EVM
Yes, I understand you are looking for the connection scheme without the EVM. The USB2ANY connections to the PGA900 are shown on the EVM schematic. The connections you have to make without the EVM are the same as the connections that are shown on the EVM.
