static void sm_config_set_out_shift ( pio_sm_config *c, bool shift_right, bool autopull, uint pull_threshold)

void pio_sm_set_consecutive_pindirs ( PIO pio, uint sm, uint pin_base, uint pin_count, bool is_out) static void pio_set_irqn_source_mask_enabled ( PIO pio, uint irq_index, uint32_t source_mask, bool enabled) has been chosen as the length of the base line A-D because it is a multiple of 4, the largest side of the 3-4-5 triangle other than the hypotenuse. The base line is regarded as true (accurate - a genuinely straight line), and so the longest available edge, ie, the '4' always goes along the base line.

Steel Rebar Setting Out Pins

In the absence of an automatic or laser level, we can use a straight edged timber and a good spirit levelto transfer the level from point R to points L and M, and then add 35mm. Small boat levels, 200-300mm long are not usually accurate enough for this sort of work, and so we recommend a spirit level at least 1200mm in length to be accurate when transferring the level by means of a straight edged timber, 3 to 4 metres in length. However, it is obvious that even a 4m straight edge will not span the distance from R to L or M, and so we set up a temporary intermediate level. Using a straightedge and spirit level to transfer levels Putting this knowledge to practical use, we can see from the construction plan for the driveway that the shape of the drive is constructed from a series of rectangles and arcs. The most important line to be set-out is the left-hand edge of the driveway, line A-B marked in red on the drawing, which is perpendicular to the front of the house, and is aligned with the left-hand edge of the doorway. To establish this perpendicular, we use a 3-4-5 triangle. We provide varying types of flags in different colours to out specific areas/objects and are a very cost effective way to help with general surveying tasks. For other type of marking out then wooden stakes work well and our road pins are perfect for concrete form work. Pins and pegs are used in surveying to mark points on the ground for reference. They are usually made of metal or wood and are driven into the ground to make a visible mark. They are important as they serve to separate the boundaries.

The brief is to create a drive 7 metres wide, which is to align with the left hand edge of the front door, with a curved sweep on the right hand side to accommodate the double width garage and a smaller curve on the left hand side to tie in with a 1.2m wide pathway along the front of the property. From these two fixed points, A and D, we now mark out two arcs. These can be scratches on the ground, sand lines, spray paint, crayon or anything that can make a mark. From Point A we mark out a 6m arc, ie, the '3' side of the 3-4-5 triangle, and from Point D we mark out a 10m arc, ie, the '5', the hypotenuse. Where these two arcs intersect, Point E, marks the apex of a 3-4-5 triangle. On the plan below, the marker pins have been positioned at 750mm centre to centre (c/c) along the arcs. Once in position, a taut string line can be fastened to the pins to create a line guide for the laying of the arcs. For our right angled triangle we need to be as exact as possible with our measurements to ensure we get a true right angle at 90°, and not at 88° or 91°, so a measure is made along the front of the house, from the LH edge of the doorway at 'A' and a distance of 8m is marked with crayon or chalk at point D, just to the right of the garage door.Point Y is similarly established, by levelling across from the line established between K and R at point X. However, at this point, we do not want the path to fall towards the house, as we did for the previous point, as there is no gully at point X. Therefore, we will set Point Y at 10mm below point X. static void pio_set_irqn_source_enabled ( PIO pio, uint irq_index, enum pio_interrupt_source source, bool enabled) The dimensions on the drawing states that the distance from the left hand edge of the front doorway (A), to the right hand corner of the property (C) is 7m + 3m = 10m. However, most landscape plans are drawn at a scale of 1:100 or greater, and will usually have an accuracy of around ±50mm. Point Q is established by extrapolating the line N-L until it intercepts the line K-R at point Z. The taut string line will just touch the pin at Q, which can then be marked for paving level.

Please keep your proof of postage from the Post Office until we have confirmed that we have received your returned items. These Setting Out Pegs have been approved under our Project Kaiyo™ initiative, accomplishing one or more of our environmentally friendly objectives. In this case, this product is made with recycled materials.All paving and landscape projects need to be 'set out' - this is the process of using geometry to establish lines, levels, curves and arcs, as well as positioning other features in relation to a given point, typically a house, or other building. Spray Paints are suitable for permanently marking nearly all types of surface and general purpose non-toxic wax Crayons are available in many different colours and are suited for marking on nearly any surface. We have various types of Chalk for temporary marking and our engineers Chalk is specifically suited for metal, specifically steel. The SCCS Chalk line (refills available) are perfect for drawing straight lines on concrete, plaster, metal. We know that the gully at K is 90mm below R, so Points L and M need to be 125 - 90 = 35mm higher than point R, which means it would be 150mm - 35mm = 115mm below DPC level. Use a state machine to set the same pin direction for multiple consecutive pins for the PIO instance.
