Example text

My strong recommendation is that you only use a relatively high-speed class 10 micro SD card in order to minimize any processing delays that will likely occur when transferring data between the card and the Pyboard. Bare-Metal Approach I am concluding this first chapter with a discussion of the bare-metal approach that Dr. George decided to take when creating MicroPython. fm, episode #17. 4. The main goals in this rewrite were to make this Python version as efficient as possible and to use the least amount of RAM necessary to execute any operation.

The reason I elected to show you this schematic is to point out that there are only four integrated chips on the board. Table 2-1 lists these chips and their principal functions. Table 2-1 膕Pyboard Integrated Chips and Their Functions The main chip舒and the largest one舒is the STM microcontroller chip (known as STM micro henceforth), which is the heart of the Pyboard. It is a sophisticated 32-bit microcontroller with an ARM Cortex-M4 processor core. Some of the key specifications for this chip are detailed in Table 2-2 .

Or do you simply say 舠Please take me to Radio City Music Hall舡? The first approach is procedural, whereas the latter is object oriented. In taking the OO approach, you are relying on that person object (the taxi driver) to be responsible for accepting a message 舠Please take me to Radio City Music Hall舡 and know how to accomplish the task. , but you as the message sender will not be aware of this change. You have to be aware of all the traffic conditions in New York City if you choose the procedural approach.
