The beta cells in the pancreas of people with type 1 diabetes are not able to produce insulin.
For people without diabetes, the pancreas releases a number of hormones for glucose homeostasis. PSoC programmable analog & digital resources integrate everything shown in light blue below.
Blood glucose meters measure the amount of glucose in blood of diabetics allowing for the administration of the proper dose of insulin to maintain balance. PSoC 3 & PSoC 5 enables a scalable one chip glucose meter solution that flexibly integrates all the basic and advance requirements of a glucose meter. This application note describes how to configure the direct memory access (DMA) to buffer the analog-to-digital converter (ADC) data. Cypress's PSoC programmable system-on-chip architecture gives you the freedom; to not only imagine revolutionary new products, but the capability to also get those products to market faster than anyone else.
The movement of patient care away from hospitals and clinics and into homes is a growing trend.
The Blood Glucose Meter board has been designed to facilitate demonstrations which show PSoC3’s flexibility and analog capabilities in such Portable Handheld devices.
The diagram shows how kidney function reduces and the amount of protein in the urine increases in diabetic nephropathy. The overall risk of developing diabetic nephropathy varies between about 10% of type II diabetics (diabetes of late onset) to about 30% of type I diabetics (diabetes of early onset). Given the relatively predictable nature of diabetic nephropathy , a kidney biopsy is usually not needed.
High blood pressure almost always develops or worsens in diabetic nephropathy, and can be the first abnormality to develop. Blood glucose control Good blood glucose control can prevent the development and slow the progression of diabetic nephropathy, as well as preventing the other complications of diabetes, even if kidney failure has developed.
Using ACE inhibitors and AT II antagonists Two classes of drug used to control blood pressure deserve special mention.

Diet Above and beyond the diabetic diet, not adding any salt and reducing alcohol intake will have beneficial effects on blood pressure. Controlling blood fat and cholesterol Controlling blood fat and cholesterol levels helps prevent heart disease and possibly strokes, and may slow the progression of diabetic kidney disease.
Smoking You really shouldn't smoke, not only for the sake of your kidneys, but also for the sake of your heart and brain blood vessels. The risk of diabetic nephropathy is greater when the control of blood glucose is poor, as well as in those diabetic patients who have high blood pressure and are smoker.
Diabetic nephropathy is a sign of worsening blood vessel disease throughout the body, and is associated with an increased risk of heart attack, stroke and circulatory problems. The risk and effect of diabetic nephropathy can be reduced by controlling blood sugar, blood pressure and cholestrol levels.
Glucose meters require a precision analog front end to interface to the optical or bio-sensor based glucose sensor.
Furthermore, the programmable analog front end enabled in PSoC 3 & PSoC 5 provides a more flexible solution for interfacing to the glucose sensor. It presents different approaches for using the IDACs in applications, and discusses the advantages and disadvantages of the topologies presented.
It discusses how to overcome some of the limitations of the DMA when buffering the ADC data. Explore PSoC 3's precision analog capabilities through the on board 20-bit Delta Sigma ADC used to measure voltage ranges between -30 V and 30 V.
It begins with a tiny amount of protein appearing in the urine - this is called microalbuminuria.
With the development of proteinuria, the kidneys' ability to remove poisons from the blood deteriorates such that 5-10 years later the kidneys are almost completely unable to remove these poisons from the blood. There are many factors, some known and others not, that affect the individual risk of developing diabetic nephropathy. You will be evaluated by history, examination, as well as blood and urine tests and a kidney ultrasound examination.

Diabetic eye disease is usually present by this stage indicating damage to smaller blood vessels.
Smokers die earlier than non-smokers, but diabetic smokers die much earlier and often develop serious circulation problems at a young age. The sensor detects the optical properties of the chemical strip as it reacts with a blood sample. This enables a more scalable platform that can be utilized across multiple glucose meter designs and strip technologies. A variety of HID devices, including a keyboard with LEDs and a composite device, are used as examples.
The design allows for self calibration itself using an internal IDAC and provides sampling rates in excess of 10,000 sps with 3nA resolution. After many years of diabetes the delicate filtering system in the kidney becomes destroyed, initially becoming leaky to large blood proteins such as albumin which are then lost in urine. If there are unusual features, then further investigations may be needed to define the kidney condition, and this may well involve a biopsy. Larger blood vessels (arteries) are almost always affected leading to heart attacks, strokes, and circulatory disease occurring more often and at a younger age than usual. The analog front end includes up to four channels of trans impedance amplifiers with a gain stage, a precision ADC, and a very accurate voltage reference. A library is also included that implements three of the methods as PSoC Creator? components. Other design requirements include LCD drive, Real time Clock (RTC), very low power consumption and user interface.
Consistent performance across temperature (0-50C) is also essential to ensure accurate diagnosis of unsafe blood glucose levels.
