This demo provides an example of how to do that. +.PP +The objective of the demo is to decode radio-controlled model PWM signals, and control an output PWM based on the current input signal's value. The incoming PWM pulses follow a standard encoding scheme where a pulse width of 920 microseconds denotes one end of the scale (represented as 0 % pulse width on output), and 2120 microseconds mark the other end (100 % output PWM). Normally, multiple channels would be encoded that way in subsequent pulses, followed by a larger gap, so the entire frame will repeat each 14 through 20 ms, but this is ignored for the purpose of the demo, so only a single input PWM channel is assumed. +.PP +The basic challenge is to use the cheapest controller available for the task, an ATtiny13 that has only a single timer channel. As this timer channel is required to run the outgoing PWM signal generation, the incoming PWM decoding had to be adjusted to the constraints set by the outgoing PWM. +.PP +As PWM generation toggles the counting direction of timer 0 between up and down after each 256 timer cycles, the current time cannot be deduced by reading TCNT0 only, but the current counting direction of the timer needs to be considered as well. This requires servicing interrupts whenever the timer hits \fITOP\fP (255) and \fIBOTTOM\fP (0) to learn about each change of the counting direction. For PWM generation, it is usually desired to run it at the highest possible speed so filtering the PWM frequency from the modulated output signal is made easy. Thus, the PWM timer runs at full CPU speed. This causes the overflow and compare match interrupts to be triggered each 256 CPU clocks, so they must run with the minimal number of processor cycles possible in order to not impose a too high CPU load by these interrupt service routines. This is the main reason to implement the entire interrupt handling in fine-tuned assembly code rather than in C. +.PP +In order to verify parts of the algorithm, and the underlying hardware, the demo has been set up in a way so the pin-compatible but more expensive ATtiny45 (or its siblings ATtiny25 and ATtiny85) could be used as well. In that case, no separate assembly code is required, as two timer channels are avaible. +.SH "Hardware setup" +.PP +The incoming PWM pulse train is fed into PB4. It will generate a pin change interrupt there on eache edge of the incoming signal. +.PP +The outgoing PWM is generated through OC0B of timer channel 0 (PB1). For demonstration purposes, a LED should be connected to that pin (like, one of the LEDs of an STK500). +.PP +The controllers run on their internal calibrated RC oscillators, 1.2 MHz on the ATtiny13, and 1.0 MHz on the ATtiny45. +.SH "A code walkthrough" +.PP +.SS "asmdemo.c" +After the usual include files, two variables are defined. The first one, \fCpwm_incoming\fP is used to communicate the most recent pulse width detected by the incoming PWM decoder up to the main loop. +.PP +The second variable actually only constitutes of a single bit, \fCintbits.pwm_received\fP. This bit will be set whenever the incoming PWM decoder has updated \fCpwm_incoming\fP. +.PP +Both variables are marked \fIvolatile\fP to ensure their readers will always pick up an updated value, as both variables will be set by interrupt service routines. +.PP +The function \fCioinit()\fP initializes the microcontroller peripheral devices. In particular, it starts timer 0 to generate the outgoing PWM signal on OC0B. Setting OCR0A to 255 (which is the \fITOP\fP value of timer 0) is used to generate a timer 0 overflow A interrupt on the ATtiny13. This interrupt is used to inform the incoming PWM decoder that the counting direction of channel 0 is just changing from up to down. Likewise, an overflow interrupt will be generated whenever the countdown reached \fIBOTTOM\fP (value 0), where the counter will again alter its counting direction to upwards. This information is needed in order to know whether the current counter value of \fCTCNT0\fP is to be evaluated from bottom or top. +.PP +Further, \fCioinit()\fP activates the pin-change interrupt \fCPCINT0\fP on any edge of PB4. Finally, PB1 (OC0B) will be activated as an output pin, and global interrupts are being enabled. +.PP +In the ATtiny45 setup, the C code contains an ISR for \fCPCINT0\fP. At each pin-change interrupt, it will first be analyzed whether the interrupt was caused by a rising or a falling edge. In case of the rising edge, timer 1 will be started with a prescaler of 16 after clearing the current timer value. Then, at the falling edge, the current timer value will be recorded (and timer 1 stopped), the pin-change interrupt will be suspended, and the upper layer will be notified that the incoming PWM measurement data is available. +.PP +Function \fCmain()\fP first initializes the hardware by calling \fCioinit()\fP, and then waits until some incoming PWM value is available. If it is, the output PWM will be adjusted by computing the relative value of the incoming PWM. Finally, the pin-change interrupt is re-enabled, and the CPU is put to sleep. +.SS "project.h" +In order for the interrupt service routines to be as fast as possible, some of the CPU registers are set aside completely for use by these routines, so the compiler would not use them for C code. This is arranged for in \fCproject.h\fP. +.PP +The file is divided into one section that will be used by the assembly source code, and another one to be used by C code. The assembly part is distinguished by the preprocessing macro \fC__ASSEMBLER__\fP (which will be automatically set by the compiler front-end when preprocessing an assembly-language file), and it contains just macros that give symbolic names to a number of CPU registers. The preprocessor will then replace the symbolic names by their right-hand side definitions before calling the assembler. +.PP +In C code, the compiler needs to see variable declarations for these objects. This is done by using declarations that bind a variable permanently to a CPU register (see \fBHow to permanently bind a variable to a register?\fP). Even in case the C code never has a need to access these variables, declaring the register binding that way causes the compiler to not use these registers in C code at all. +.PP +The \fCflags\fP variable needs to be in the range of r16 through r31 as it is the target of a \fIload immediate\fP (or \fCSER\fP) instruction that is not applicable to the entire register file. +.SS "isrs.S" +This file is a preprocessed assembly source file. The C preprocessor will be run by the compiler front-end first, resolving all \fCinclude\fP, \fCdefine\fP etc. directives. The resulting program text will then be passed on to the assembler. +.PP +As the C preprocessor strips all C-style comments, preprocessed assembly source files can have both, C-style (\fC/* ... \fP +.PP + diff -urN --exclude=CVS --exclude=.cvsignore --exclude=.svn --exclude=.svnignore old/man/man3/assembler.3 new/man/man3/assembler.3 --- old/man/man3/assembler.3 2006-04-20 23:32:52.000000000 +0200 +++ new/man/man3/assembler.3 2006-10-09 22:29:27.000000000 +0200 @@ -1,4 +1,4 @@ -.TH "assembler" 3 "20 Apr 2006" "Version 1.4.4" "avr-libc" \" -*- nroff -*- +.TH "assembler" 3 "9 Oct 2006" "Version 1.4.5" "avr-libc" \" -*- nroff -*- .ad l .nh .SH NAME diff -urN --exclude=CVS --exclude=.cvsignore --exclude=.svn --exclude=.svnignore old/man/man3/avr_assert.3 new/man/man3/avr_assert.3 --- old/man/man3/avr_assert.3 2006-04-20 23:32:53.000000000 +0200 +++ new/man/man3/avr_assert.3 2006-10-09 22:29:29.000000000 +0200 @@ -1,4 +1,4 @@ -.TH ": Diagnostics" 3 "20 Apr 2006" "Version 1.4.4" "avr-libc" \" -*- nroff -*- +.TH ": Diagnostics" 3 "9 Oct 2006" "Version 1.4.5" "avr-libc" \" -*- nroff -*- .ad l .nh .SH NAME diff -urN --exclude=CVS --exclude=.cvsignore --exclude=.svn --exclude=.svnignore old/man/man3/avr_boot.3 new/man/man3/avr_boot.3 --- old/man/man3/avr_boot.3 2006-04-20 23:32:53.000000000 +0200 +++ new/man/man3/avr_boot.3 2006-10-09 22:29:29.000000000 +0200 @@ -1,4 +1,4 @@ -.TH ": Bootloader Support Utilities" 3 "20 Apr 2006" "Version 1.4.4" "avr-libc" \" -*- nroff -*- +.TH ": Bootloader Support Utilities" 3 "9 Oct 2006" "Version 1.4.5" "avr-libc" \" -*- nroff -*- .ad l .nh .SH NAME @@ -14,6 +14,8 @@ .PP The macros in this module provide a C language interface to the bootloader support functionality of certain AVR processors.
