We are switching from STM32 to the Russian K1986BE92QI microcontroller. Practical application: Generate and reproduce sound. Part Four: We create the digital part of a single-voiced and multi-voiced music postcard
Introduction
In this article we will finish the topic of sound generation using our microcontroller. Create a monophonic and multi-voiced basis for a music card.
Making a monophonic music card: playing a simple melody.
In order to consolidate the ability to work with timers, I suggest to write a program that will play us a small tune. Something like a music postcard. To begin with, understand. Sinusoid for all notes is the same. The difference in pitch is created due to the different speed of the output of this sinusoid to the amplifier. In other words, changing the timer parameters - we change the pitch of the note. DMA transmits the same sine wave.
Let's write a function that will change the pitch.
Also recall that when we initialized the timer, we already gave out our sinusoid with a certain frequency. You should remove the “sound” notes from the initialization function.void SM_Ton (uint32_t TN) // . { TIMER1->CNTRL = 0; // . TIMER2->CNTRL = 0; TIMER1->CNT = 0; // . TIMER2->CNT = 0; TIMER1->ARR = TN; // . TIMER2->ARR = TN*25; DAC_ST_ADC[10-1].channel_cfg = (uint32_t)(DMA_DAC_InitST_PR); // DMA. DAC_ST_ADC[10-1+32].channel_cfg = (uint32_t)(DMA_DAC_InitST_ALT); TIMER1->CNTRL = CNTRL_CNT_EN; // . TIMER2->CNTRL = CNTRL_CNT_EN; } We get the following.
void Init_TIMER1_to_DMA_and_DAC2 (void) { RST_CLK->PER_CLOCK |= PER_CLOCK_TIMER1_ONCLK|PER_CLOCK_TIMER2_ONCLK; // 1 2. RST_CLK->TIM_CLOCK = 0; // . TIMER1->DMA_RE |= DMA_RE_CNT_ARR_EVENT_RE; // DMA. TIMER2->IE = TIMERx_IE_CNT_ARR_EVENT_IE; // . TIMER2->STATUS=0; // . NVIC->ISER[0] = 1<<15; // 2. RST_CLK->TIM_CLOCK = TIM_CLOCK_TIM1_CLK_EN|TIM_CLOCK_TIM2_CLK_EN; // . } Next, we need to write a function that will turn off the sound.
void Ton_off (void) { TIMER1->CNTRL = 0; // . TIMER2->CNTRL = 0; } Next you need to create an array of frequencies of notes. Make it three octaves
Measure the duration of the notes will be a system timer. This is the easiest way. We will adjust it so that at a given speed of beats per minute (I, as a musician, is more familiar), we can measure notes to the sixteenth . #define HCLK_MY_TIMDEL 8000000/100 uint32_t music_books[37] = { HCLK_MY_TIMDEL/130.82, //C_3 HCLK_MY_TIMDEL/138.59, HCLK_MY_TIMDEL/147.83, HCLK_MY_TIMDEL/155.56, HCLK_MY_TIMDEL/164.81, HCLK_MY_TIMDEL/174.62, HCLK_MY_TIMDEL/185, HCLK_MY_TIMDEL/196, HCLK_MY_TIMDEL/207, HCLK_MY_TIMDEL/220, HCLK_MY_TIMDEL/233.08, HCLK_MY_TIMDEL/246.96, HCLK_MY_TIMDEL/261.63, //C_4 HCLK_MY_TIMDEL/277.18, HCLK_MY_TIMDEL/293.33, HCLK_MY_TIMDEL/311.13, HCLK_MY_TIMDEL/329.63, HCLK_MY_TIMDEL/349.23, HCLK_MY_TIMDEL/369.99, HCLK_MY_TIMDEL/392, HCLK_MY_TIMDEL/415.30, HCLK_MY_TIMDEL/440, HCLK_MY_TIMDEL/466.16, HCLK_MY_TIMDEL/493.88, HCLK_MY_TIMDEL/523.25, //C_5 HCLK_MY_TIMDEL/554.36, HCLK_MY_TIMDEL/587.32, HCLK_MY_TIMDEL/622.26, HCLK_MY_TIMDEL/659.26, HCLK_MY_TIMDEL/698.46, HCLK_MY_TIMDEL/739.98, HCLK_MY_TIMDEL/784, HCLK_MY_TIMDEL/830.60, HCLK_MY_TIMDEL/880, HCLK_MY_TIMDEL/932.32, HCLK_MY_TIMDEL/987.75, 0 // }; Sixteenth pause
#define TactSpeed 60 // . //------------------------------------------------- // . //------------------------------------------------- void Init_SysTick (void) { SysTick->LOAD = 80000000*60*4/TactSpeed/16; //80000000*60*4/TactSpeed - . // . SysTick->CTRL |= CLKSOURCE|TCKINT|ENABLE; } volatile uint32_t Delay_dec = 0; void Delay (uint32_t Delay_Data) // SysTick . { Delay_dec = Delay_Data; while (Delay_dec) {}; } void SysTick_Handler (void) { if (Delay_dec!=0) Delay_dec--; } The next step we need to decide where to get the data. Having tried several options, I chose the closest one to my liking. He is the easiest. Here is the melody preparation algorithm:
- Download any melody in MIDI format. With one channel (or later so that you can choose one). I downloaded Elfen Lied - Lilium as a test.
- Next, we need to translate our MIDI into an array consisting of a note number / pause number and its duration. To do this, download the program Ringtone Editor v2.2 . From it we get a text file in siemeans format.A little help on the program.
- Turn on the program, open our MIDI file. If it has many channels, select the one you need. Click ok.
- After that, we see the created text-note track. It consists of the names of the notes and their durations. In its format.
- We can listen to our song. If you don’t like something, we can edit the notes (useful when the melody is not exactly divided into 2 parts). Remember that our composition must contain notes with a duration of more than sixteenth (excluding the sixteenth with a dot. To create it, you need to add thirty-two to the duration of the sixteenth, and for this you need to change the timer settings). And also the notes should be within the three octaves described.
- In order to edit a note, you need to click on it with the left mouse button (it will be highlighted with a rectangle) and, holding Ctrl, press the up or down arrow on the keyboard.
After editing (editing and trimming the melody), I got such a file . - After that we save our file in text format. I got this file .
- Turn on the program, open our MIDI file. If it has many channels, select the one you need. Click ok.
- As I said, the program generates data in its format. In order to make life easier and not to translate everything under our example manually (every note), I wrote a program that converts the data into an array we need: note / duration.Here is her codeProgram Pr;

Making a multi-voiced musical card.
We made a monophonic music card. But you want more. Let's complicate the task. Let's make the controller play polyphonic melodies. Let's do the example of our work. It has 2 channels. We will play them.
Question: how to mix two or more waves? As we remember, this article dealt with methods for generating sound waves. The principle of superposition was also shown there. Well. How to impose know, but how to organize it? I went the following way:
- Create an array of 2048 elements (you can take more or less, it is not crucial).I have it looks like this.
uint16_t BufferData [1024*2]; // . - Set up the timers from the previous lesson so that the DMA outputs this array indefinitely at a fixed frequency (this way we will free ourselves from the “game” with timers). My timer relies on the frequency of 80 MHz (In fact, much slower speed will suffice, but just in case I use it, all of a sudden the task will be too tough. Remaining at the end for a lower frequency will not be difficult). The speed of issuing let it be 32,000 Hz.This is how the timer settings function looks like.
// 2048 . 32000 . void Init_TIMER1_to_DMA_and_DAC2_for_BUFFER (void) { RST_CLK->PER_CLOCK |= PER_CLOCK_TIMER1_ONCLK|PER_CLOCK_TIMER2_ONCLK; // 1 2. RST_CLK->TIM_CLOCK = 0; // . // 800000000 /32000 = 2500. TIMER1->ARR = 2500; // ... TIMER1->DMA_RE |= DMA_RE_CNT_ARR_EVENT_RE; // DMA. TIMER2->ARR = 2500*512/128; // . TIMER2->IE = TIMERx_IE_CNT_ARR_EVENT_IE; // . TIMER2->PSG = 128-1; // 128. TIMER2->STATUS=0; // . NVIC->ISER[0] = 1<<15; // 2. TIMER1->CNTRL = CNTRL_CNT_EN; // . TIMER2->CNTRL = CNTRL_CNT_EN; RST_CLK->TIM_CLOCK = TIM_CLOCK_TIM1_CLK_EN|TIM_CLOCK_TIM2_CLK_EN; // . } - In the DMA setup function, we leave everything the same, except the array name.Now we use the one we created above.
struct DAC_ST { uint32_t Destination_end_pointer; // . uint32_t Source_end_pointer; // uint32_t channel_cfg; // . uint32_t NULL; // . } __align(1024) DAC_ST; // 1024 . struct DAC_ST DAC_ST_ADC[32+32]; // . /// = 16 , / = 16 , , 50 , -. uint32_t DMA_DAC_InitST_PR = dst_src|src_inc|src_size|dst_size|n_minus_1|cycle_ctrl; uint32_t DMA_DAC_InitST_ALT = dst_src|src_inc|src_size|dst_size|n_minus_1|cycle_ctrl; //------------------------------------------------- // DMA DAC. //------------------------------------------------- void DMA_to_DAC_and_TIM1 (void) { // . DAC_ST_ADC[10-1].Destination_end_pointer = (uint32_t)BufferData + (sizeof(BufferData))/2 - 1; // (C_4 - 100 ). DAC_ST_ADC[10-1].Source_end_pointer = (uint32_t)&(DAC->DAC2_DATA); // ( ) ( DAC). DAC_ST_ADC[10-1].channel_cfg = (uint32_t)(DMA_DAC_InitST_PR); // . DAC_ST_ADC[10-1].NULL = (uint32_t)0; // . // . DAC_ST_ADC[10-1+32].Destination_end_pointer = (uint32_t)BufferData + sizeof(BufferData) - 1; // (C_4 - 100 ). DAC_ST_ADC[10-1+32].Source_end_pointer = (uint32_t)&(DAC->DAC2_DATA); // ( ) ( DAC). DAC_ST_ADC[10-1+32].channel_cfg = (uint32_t)(DMA_DAC_InitST_ALT); // . DAC_ST_ADC[10-1+32].NULL = (uint32_t)0; // . // DMA. RST_CLK->PER_CLOCK|=PCLK_EN_DMA; // DMA. DMA->CTRL_BASE_PTR = (uint32_t)&DAC_ST_ADC; // . DMA->CFG = CFG_master_enable; // DMA. // . DMA->CHNL_ENABLE_SET = 1<<10; // 10 . } - Next you need in the settings of the channel structure (both primary and alternative have the same setting, as in the previous article) specify a different number of programs. In the last article, we used an array of 100 values. Now we will use all 1024 available (with the expectation that we will have to turn to interruption less often).Modified structure.
//------------------------------------------------- // . //------------------------------------------------- #define dst_src (3<<30) // - 16 (). #define src_inc (1<<26) // 16 . #define src_size (1<<24) // 16 . #define dst_size (1<<28) // 16 . . #define n_minus_1 ((1024-1)<<4) //1024 (-1) DMA. #define cycle_ctrl (3<<0) //-. - The next step is to decide how we will fill our array. The initial idea was to generate wave values ​​in each time period directly in the MC. But as practice has shown, even 80 MHz is not enough for this task (in order to simultaneously issue and fill in the new values ​​with the already transmitted cells). Perhaps you can find a solution and generate inside the MC, but I failed. I decided to do so. I wrote a program that, at a given frequency of changing DAC values, generates a set of values ​​for each note in the range of three octaves. After in MK we can copy these values ​​to the buffer and change them in every way.Program code Written in Pascal ABC.Download the program here .

Thus, during each interruption, we can allow overwriting of already transferred 512 blocks.Here is the code for the modified interrupt.
