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 calibration […]

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 […]

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 […]
