PGM is a specialised programming control pin, useful only in a production environment, and is used for low volt programming See Section below on PGM. PIC chips come with the PGM interface enabled so that a PIC chip can be inserted into a production board and can be programmed by another device at the system level voltage.
So you could have a situation where several PIC devices are connected to a master device and are re-programmable in the unit possibly over the web etc. Note: When you develop a board quickly e. With the 10k only; When programming, Does it put high voltage against the 5V? Note: With the connections made in this order on the connector it will not matter if the connector is placed the wrong way round as GND and VCC are then applied to clock and data.
Vpp connects to the reset input of the pic microcontroller labelled MCLR. During programming or verify this signal is raised to the programming voltage Note: Older pic micros used this line to directly power the programming circuit that updates the Flash memory. So this connection had to supply some current. This connection may supply power to your board - usually using a 5V regulator probably a This is ok for some use as you can develop a prototype board without needing any other power supply just a power brick that plugs into the pic programmer circuit.
The only problem with it is that the programmer circuit is not designed for your circuit does it have a heatsink and it can also introduce noise to your circuit. If the programmer uses a 78L05 then you will only get mA maximum current output. These are the signals that do the work. Well, I don't personally know what I think about this. It's progressive music on brave, uncharted ground at least, it was uncharted in the s comparatively.
Noise, perhaps the most vilified of genres in music, still holds some level of respectability in the development of music in the post-modernist age. If we didn't have Lou Reed's Metal Machine Music, we wouldn't have the noise genre, at least not to the truly huge extent we do now.
Say what you will about its artistic credability - that it inspired nearly an entire genre through its dissonant guitar feedback riddled 64 minute double vinyl packaged as a live album which was expensive at the time, heh , speaks for itself. It is another single song album, like MMM, except rather then seemingly 'random' chunks of feedback riddling its length, instead we have a single, piercing sample, looped over and over for the length of the piece.
Now, if I said that this single sample barely changed over the course of the albums length, that would, for a large majority of you - signal that this is probably not going to be your cup of tea. True, noise music contains some of the most abrasive sound one could expect, just wade through Merzbow's discography and take a pick. But what makes Consume Red such an experience, despite its daunting length, inability to simply skip through the parts - is that it represents a slow, ever so slow build upon this almost unchanging sample - there are subtle manipulations to begin with.
In the first five minutes we begin to get feedback, some squeals and groans against the still pure and almost hypnotising sample of a sacred Korean instrument known as a hojok. They copped some controversy for the blatant sampling, but it has since passed. Moving forward, the first 15 minutes appear uneventful. The feedback, despite being abrupt and sudden, is still consciously building up. There is motion and with it, a forceful burst of life.
Drums begin to emerge. Saxophone, and various other instruments begin to peak from among the sample. They merge and interweave, break away and disappear, then reappear completely different. Just to be aware - this is not the impression you will likely get on first listen. Suddenly, the building noise reaches a climax at the twenty fifth minute, where the true 'noise' aspect of the piece finally shows up.
The drums burst erratically, the saxophone churns out an almost indiscernable tune, the bass noodles beneath and rises with the drum beats - there is a lot going on. And still, underneath this now imposing wall of sound, the sample plays on. There feels like there is no limit to the places that you can seek out in this world of noise. At times I felt like there were even voices and nature sounds spread amongst this piece. The drum beat settles from the thirty minute mark to a far more polished and almost top tappy segment for the next fifteen minutes, where the sample, drums, bass, guitar and all the other instruments however slight they contribute - push forward the piece to its final ten minutes.
Here, the piece finally starts to wear down, the noise cascades and crumbles in the same breath, the hojok sample plays on, but grows at times indiscernable behind the cacophony. Suddenly, with four minutes left, everything seems to stop, except the feedback, which rises and falls, as if the hojok still accompanies it, then fades to silence. Ground Zero's Consume Red illustrates one such extreme of genre mixing, being avant prog with noise music.
Ultimately, what makes this piece so seminal to noise affectionados, I can only assume, is the consistent building soundscape and atomsphere, driven on by a continuous Korean hojok, which ultimately never changes throughout the epic, 57 minute piece, more develops as the sounds around it take hold, until the ultimate result is that the hojok becomes indistingushable amidst the onslaught of saxophone, guitars, feedback and drums. I will admit, I am not yet a noise fan, but this album has grown on me in ways I hadn't expected.
In his last diary entry he wrote that he knows that one day he is going to be stabbed to death. Later that week, he was indeed stabbed to death in a park, by a young Parisian man who was probably his lover, for reasons which remained unknown. The music of Vivier is enchanting. The listener is easily drawn to the strange long melodies and the scents and spices of this newly undiscovered land of dreams and beauty.
I recommend listening first to his beautiful tone-poem " Lonely Child " , for soprano and orchestra and to Zipangu , for string orchestra. Yet, although he is considered the finest Canadian composer of all times Ligeti referred to him as the finest French composer of his generation , the music of Claude Vivier is widely unknown and seldomly performed or recorded.
While most of his contemporaries in Europe continued their remote mathematical researches in music, and his contemporaries in America became fond of minimalism and of Neo-Romanticism, Claude Vivier found his unique voice, that didn't sound like anything else.
In an age where true beauty is a foul word and so rare to find and usually associated with Neo romanticism and fully tonal music , Vivier's music is nothing less than a wonderful, astonishing discovery. Friday, 9 January Ground Zero.
Today you find yourself in an aggressive mood. A car's siren woke you up from a bad dream featuring your mother being gang-banged by a group of fourteen dwarfs. Your girlfriend just told you she's a lesbian, your dog is basically a cat, you find that you are adopted, and that NOISE of that car's siren drives you mad.
Wait a moment, it is not only a car, it's a whole army marching down your very own street. You are asking yourself what the hell are they doing here, but you cannot finish your thought, as your upstairs neighbor has just activated his newly purchased vacuum cleaner. The noise from upstairs would be very dominant, unless the slightly retarded son of Mr. Rabinovich would not be practicing the drums all afternoon, and from the next-door apartment the old and deaf Mrs.
Kavanova would not scream at her dead husband all day. As it is constantly multi-layered and so many things happen simultaneously, your ear is being assaulted by this hardcore blend of sounds- including car noises, sirens, all kinds of drums, turntables played by Otomo Yushihide, also very famous in the scene on his own , occasional screams in Japanese, original samples, lots of feedback, great saxophone playing and lots of other unrecognizable noises. Basically, All-in-one.
Or, in other words, everything needed for your neighbor to finally file a law suit against you and convince the others to get you out of the building, pronto. Their most ambitious and perhaps best well-known project was Consume Red, a 57 minute continuous piece, which begins with a repetitive sample of a Korean reed instrument.
