Linear Interpolation Extension Employing Three-Gradient

Speed and Memory Size Optimization When developing digital signal processor for Deepstomp, we employs a cheap 32-bit processor without floating point unit. Consequently, we have to optimize all computation in fix point math. The most important effect, especially for electric guitar, is distortion effect. It is simulated using sigmoid or sigmoid-like functions such arctan, tanh, or some others. Those functions […]

Multi-Channel Expansion Oversampling: 15Bit from 12Bit ADC

Introduction: Analog-to-Digital Conversion Oversampling Every analog-to-digital conversion is designed for specific resolution depending on the bit (binary digit) width of the conversion. For example, a 10 bit ADC with 5V reference would have 5V/1024 resolution or about 4.883 mV. The intrinsic error related to the resolution is the digital-quantization error  of ±0.5 bit. In other words, it should produce only […]

16-bit Audio PWM by Dual 8-bit PWM with Auto Calibration

Introduction: PWM (Pulse-Width Modulation) for Digital Audio Conversion Pulse width modulation (PWM) technique has been widely used for converting digital audio stream into audio signal since it is very simple and easy to implement. Many low-cost micro controllers include dedicated PWM controllers as their standards, and many engineers use it for many purposes. In this article, we present the solution […]

Programming The Lock Bits Using Arduino ISP with AVRDUDE

Intoduction: Protecting The Arduino Uploaded Program Codes If you want to sell the final product developed with Arduino, then you need to protect the firmware from cloning. Similarly, you need the protection as well when selling an embedded software by selling the programmed microcontroller chip. Fortunately, there is a lock bits fuse that that is programmable using the ICSP interface. […]

HM936D-AM8 Digital Soldering Station Controller Chip – User and Developer Manual

Product Description HMC936D-AM8 is a controller chip for HM-936D digital soldering station controller board. The controller is implemented using ATMEGA8 microcontroller, programmed with lock protection to disable the chip for being read or modified. It runs on 8MHz  internal factory calibrated RC clock, so there is no need to provide XTAL and its related capacitors. The operational menu, custom sensor […]
