Hi,
We want to add a cell battery to keep time and date. but in the schemaitcs, Pin 1 and Pin 6 in STM32F429iDisco for VBAT alredy connect to +3V.What we can do?Thanks a lot2015-08-20 10:37 AM
I have an STM32F429I-DISCO with an LSE, added as described earlier. The clock starts and runs for me.
Not sure where you're implementation is falling over. If you need consulting work done on this, please contact me off board.2015-08-20 10:54 AM
Attached is a small test app that turns on the LSI and LSE, and benchmarks them against the 8 MHz HSE source.
The software outputs via the SWV (use ST-LINK SWV Viewer) at 180 MHzTest
