Lack of an evaluation board (yet) for practical experiences, I just read the documents and a question arises.
Within the SmartSnippets UI we define the GPIO pin for high voltage (6.8V). The CLI command according help:
4. SmartSnippets.exe -type otp -com_port portNumber [-baudrate rate]
-cmd write_custom_code -file filename [-offset ofst]
Burns file to OTP memory
The GPIO pin is missing. How will this work? Do I have to proved the high voltage by hand?
If I have a homebrew design, what is needed to program the OTP by CLI command?
- 2 ports for UART
- Put 6.8V to VPP (by needle adapter)
- Start CLI command
Or can I program the OTP by JTAG interface too?
Any comments are welcome.
