I have two solutions.
1) There is a pad pattern indicated by the number "23" to implement a 10P pin header. This pin header is used to program the PSoC 5LP with a programmer like MiniProg3. Any program can be written to the PSoC 5LP.
2) The PSoC 5LP has a bootloader program and the KitPorg is written to the application (bootloadable) area when shipped. You can develop your own application as a bootloadable.
Please refer the section "9. Developing Applications for PSoC 5LP" in the document "KitProg2 User Guide, Doc. # 002-10738" which is installed with the PSoC Programmer. The default location is as follows.
"C:\Program Files (x86)\Cypress\Programmer\Documents\KitProg2 User Guide.pdf"
thank you for your response. Do you know if it´s possible use all the modules that PSoC 5LP has? For example PGA?
YES, all components in the PSoC 5LP can be used including PGA. Please note that not of all pins are connected on the CY8CKIT-044 pioneer kit.
Some pins are connected to the J8 header as follows.
Please check the schematic of CY8CKIT-044 which can be downloaded from the following web page https://cypress.com/CY8CKIT-044
If you want to use more pins, I recommend to use the CY8CKIT-059 prototyping kit.
Thank you, very useful your response.
Do you know if it´s possible to program PSoC 5LP with the 2nd method and after that program PSoC 4?
The EMG signals are very low (<1mV). It would be hard to measure it using PSoC4 12-bit SAR ADC. Typically, 20-bit or better DelSig-type ADC required for such task. I haven't seen successful implementation of EMG using PSoC4. While it is surely possible, all analog front end should be developed outside of the PSoC4 using good Opamps.
As I pointed in previous post, cheapest ($1) would be using external 24-bit DelSig ADC HX711, and PSoC4 as an interface to PC. If using PSoC5 built-in into the KIT-044 board, the 10-pin connector and the MiniProg3 will cost >$50, which is a price of five CY8CKIT-059 PSoC5LP Prototyping boards!
Yes, you can program your custom project as part of the bootloadable project. Follow the steps mentioned in the guide under Section Building a Bootloadable Project for PSoC 5LP.
We have a note that mentions the things you need to consider, which should be useful:
So, if you don't use the pins P3 and P3 in the custom application that you develop, you will be able to program your 044 kit.
