I uploaded a new version of the PSU design and a new MCU design (minimal changes) to
github and
dropbox. Commit logs:
- Fixed name of MSP430 package: PT48 -> RGZ48
- Updated library after learning about technologies:
- Started using the ? and * keywords in device names, changed several parts
- Added the PT48 package to the MSP430F55*I part, added attributes
- This causes an incompatible name change in the MSP430F55XX device: use the replace command
- Added the LM3671 device
- Refinements on PSU section:
- Added 3.3V -> 2.5V PSU
- Changed all devices to default libraries
- This specifically includes changes to the CPOL parts: they were oriented the wrong way around
- Small changes to MCU:
- Changed name of VUSB to +3V3 (by changing the supply symbol)
- Removed +5V name (by deleting the supply symbol)
- Named the two USB signals DM and DP
- Added two V<-> symbols and routed them to DM and DP
@Li_gangyi: Can you verify the capacitors in the PSU? I changed them to something in the default rcl library (your parts were from a non-standard lib). But this turned the CPOL elements around. Please make sure you agree that the negative pin is marked on your parts.
@O_Shovah: You can update you local copy of the MCU.sch that you worked on by doing the following steps (maybe first open my schematic for a quick peek):
- Get the new project.lbr and update the schematic
- REPLACE the MCU device with the MSP430F5507IRGZ
- DELETE the VUSB symbol
- ADD +3V3@supply1 in its place
- DELETE the +5V symbol and the stub of wire connecting to it
- NAME the nets going to the two ESD diodes DM and DP
- ADD two V<-> symbols at these coordinates: (0.8 6.7) and (0.8 6.6). Both are rotated by 180 degrees
- Change the VALUE of each symbol: the upper one to DM, the lower one to DP
- Route a NET to the symbols, starting at the two ESD diodes
