Fixes bug introduced with last commit( Recover from bad AP access) Let STM32 timers run at 100 Hz against 10 Hz before. Programming STM32F103 failed random (#900) with 20 ms timeout requested against the 100 ms timeout granularity provided up to now. STM32 Firmware only ticked at 10 hertz, so the sequence "low_access", "set timeout", "send out 8 bit command", "read 3 bit result" when reading "wait" and timer increment tick happening during that sequence will already hits the timeout even so only mininal time has elapsed and not the requested timeout.
