An Improved Bit Banding Approach
The commonly published approach to using the bit banding feature of the Cortex Mx family of processors is to use macros – see Bit Banding in the STM32. This post describes an alternate implementation that uses a dedicated RAM section … Continue reading
Solver References
The first article that I used as a reference for Zeetah I’s solver was published in Byte Magazine back in 1987. Fortunately for me, this article was printed right around the time we were making Zeetah I. Stephen E. Belter, … Continue reading
Diagonal Solver Pseudo Code
This part of the series on creating a diagonal micromouse maze solver presents the actual pseudo code that was used to implement a diagonal solver and it closely matches the C implementation. You will want to check out some of … Continue reading

Diagonal Solver Flooding
This post provides more details on how the flooding is done.
Diagonal Solver Introduction And Flooding
If the maze has a region as shown on the left, and the mouse enters the region on the bottom left and exits on the right side, which path will your solver generate for the mouse?

Pinion interfering with the tire
When I applied power to the motors on Zeetah VI (ZVI) for the first time, the motors seemed to struggle and the PWM value to get the wheels to rotate seemed higher than usual. Since this was my first four … Continue reading

Finishing the new maze floor
The walls and posts arrived and so it was time to finish the maze floor.
Comparing the ADXRS610 and ADXRS642 gyros
Analog Devices recently release new vibration rejection gyros which seemed a perfect fit for use on a micromouse. Since I was using the ADXRS610 on Zeetah V, I temporarily mounted an ADXRS642 to ZV to compare the two.
