/**
|
|||
* This is a hybrid system. |
|||
* |
|||
* The PWM1 module is used to directly control the Servo 0, 1 & 3 pins. This keeps |
|||
* the pulse width jitter to under a microsecond. |
|||
* |
|||
* For all other pins the PWM1 module is used to generate interrupts. The ISR |
|||
* routine does the actual setting/clearing of pins. The upside is that any pin can |
|||
* have a PWM channel assigned to it. The downside is that there is more pulse width |
|||
* jitter. The jitter depends on what else is happening in the system and what ISRs |
|||
* prempt the PWM ISR. Writing to the SD card can add 20 microseconds to the pulse |
|||
* width. |

/**
|
|||
* The data structures are setup to minimize the computation done by the ISR which |
|||
* minimizes ISR execution time. Execution times are 2.2 - 3.7 microseconds. |
|||
* |
|||
* Two tables are used. active_table is used by the ISR. Changes to the table are |
|||
* are done by copying the active_table into the work_table, updating the work_table |
|||
* and then swapping the two tables. Swapping is done by manipulating pointers. |
|||
* |
|||
* Immediately after the swap the ISR uses the work_table until the start of the |
|||
* next 20mS cycle. During this transition the "work_table" is actually the table |
|||
* that was being used before the swap. The "active_table" contains the data that |
|||
* will start being used at the start of the next 20mS period. This keeps the pins |
|||
* well behaved during the transition. |
|||
* |
|||
* The ISR's priority is set to the maximum otherwise other ISRs can cause considerable |
|||
* jitter in the PWM high time. |

/**
|
|||
* Almost all changes to the hardware registers must be coordinated with the Match Register 0 (MR0) |
|||
* interrupt. The only exception is detaching pins. It doesn't matter when they go |
|||
* tristate. |
|||
* |
|||
* The LPC1768_PWM_init routine kicks off the MR0 interrupt. This interrupt is never disabled or |
|||
* delayed. |
|||
* |
|||
* The PWM_table_swap flag is set when the firmware has swapped in an updated table. It is |
|||
* cleared by the ISR during the MR0 interrupt as it completes the swap and accompanying updates. |
|||
* It serves two purposes: |
|||
* 1) Tells the ISR that the tables have been swapped |
|||
* 2) Keeps the firmware from starting a new update until the previous one has been completed. |
|||
* |
|||
* The PWM_MR0_wait flag is set when the firmware is ready to swap in an updated table and cleared by |
|||
* the ISR during the MR0 interrupt. It is used to avoid delaying the MR0 interrupt when swapping in |
|||
* an updated table. This avoids glitches in pulse width and/or repetition rate. |
|||
* |
|||
* The sequence of events during a write to a PWM channel is: |
|||
* 1) Waits until PWM_table_swap flag is false before starting |
|||
* 2) Copies the active table into the work table |
|||
* 3) Updates the work table |
|||
* NOTES - MR1-MR6 are updated at this time. The updates aren't put into use until the first |
|||
* MR0 after the LER register has been written. The LER register is written during the |
|||
* table swap process. |
|||
* - The MCR mask is created at this time. It is not used until the ISR writes the MCR |
|||
* during the MR0 interrupt in the table swap process. |
|||
* 4) Sets the PWM_MR0_wait flag |
|||
* 5) ISR clears the PWM_MR0_wait flag during the next MR0 interrupt |
|||
* 6) Once the PWM_MR0_wait flag is cleared then the firmware: |
|||
* disables the ISR interrupt |
|||
* swaps the pointers to the tables |
|||
* writes to the LER register |
|||
* sets the PWM_table_swap flag active |
|||
* re-enables the ISR |
|||
* 7) On the next interrupt the ISR changes its pointer to the work table which is now the old, |
|||
* unmodified, active table. |
|||
* 8) On the next MR0 interrupt the ISR: |
|||
* switches over to the active table |
|||
* clears the PWM_table_swap and PWM_MR0_wait flags |
|||
* updates the MCR register with the possibly new interrupt sources/assignments |
|||
* writes to the PCR register to enable the direct control of the Servo 0, 1 & 3 pins by the PWM1 module |
|||
* sets the PINSEL3 register to function/mode 0x2 for the Servo 0, 1 & 3 pins |
|||
* NOTE - PCR must be set before PINSEL |
|||
* sets the pins controlled by the ISR to their active states |
